Summary:
Before this change, fields of EmptyLayoutMetrics have some "invalid" values to allow us to compare equal them individually and get `false`. Turned out that having invalid values there might break some serialization layers, which is no good.
This change fixes that and adds explicit check for EmptyLayoutMetrics before running a comparison of individual fields.

Summary:
We don't know why exactly it happens but (seemingly) sometime Paragraph component receives an empty State object. This causes a crash because of unchecked access to an instance variable.
This diff introduces an assert in DEBUG mode and the check for prod.
Why is this happens? Hard to say, probably `layout()` method (which updates `State`) is not being called on ShadowNode. Why? One explanation can be that Yoga skips some subtree during layout because it starts from "visibility: hidden" component. We need to investigate it more and figure out what exactly going on and what should we need to improve besides the check. That's why we have an assertion.

Summary:
Starting on iOS 13, a View Controller presented modally will have a "bottom sheet" style unless it's explicitly presented full screen.
Before this, modals on iOS were only being dismissed programatically by setting `visible={false}`. However, now that the dismissal can happen on the OS side, we need a callback to be able to update the state.
This PR reuses the `onRequestClose` prop already available for tvOS and Android, and makes it work on iOS for this use case.
Should fix https://github.com/facebook/react-native/issues/26892

[iOS] [Added] - Add support for onRequestClose prop to Modal on iOS 13+
Pull Request resolved: https://github.com/facebook/react-native/pull/27618

I tested this using the RNTester app with the Modal example:
1. Select any presentation style other than the full screen ones
2. Tap Present and the modal is presented
3. Swipe down on the presented modal until dismissed
4. Tap Present again and a second modal should be presented

Summary:
We are seeing some non-trivial amount of crashes happened because `[RCTSurfacePresenter synchronouslyUpdateViewOnUIThread:props:]` requests a Component Descriptor which does not register in the registry.
And the problem here is that ComponentDescriptors are not being designed to be used outside of C++ UIManager, and we only use that in RCTSurfacePresenter only because it's an old workaround that makes Native Animation Driver works with Fabric.
Messing with ComponentDescriptors are in general dangerous. Accessing them outside of UIManager means that they might be deallocated at any time, extending their lifetime will cause other crashes on the other side. So, that's why this is "BROKEN".
This diff does not make the code worse, it just designates the problem that was there for a long time, so it kinda makes it better.

2. That will allow removing some `UnimplementedView`-specific code from the core (and very hot pathes of the system) and make them `noexcept`. That will eventually allow removing some public APIs from RawValue (constructing from folly::dynamic) that currently impose some implementation details and probably prevent us from making it slightly faster. There are only two consumers of this API, this is one of them.

Summary:
This diff removes `ComponentDescriptorProviderRegistry::remove()` and two derivative interfaces.
First, we don't use that and there is no concrete idea why we would need to use that. Those were originally built only for symmetry with limited knowledge about what exactly we need.
Second, those methods are actually dangerous and probably must not be supported by design. Removing a ComponentDescriptorProvider destroys already registered `ComponentDescriptor`s, and at the same time we might have ShadowNodes referring to that (which will cause a crash), and there is no reasonable way to check for the existence of those nodes.

Summary:
This diff introduces RCTComponentViewDescriptor - the container for a view and associated with this view properties which mounting infra uses for bookkeeping (and recycling) views.
The previous implementation used raw Objective-C pointers to `UIView`s to store and manipulate them. The new way has a bunch of advantages:
* It allows using high-performant C++ data collections for storing views and their properties (in future diffs).
* The new approach allows us to avoid hacks around NSMapTable (such as ` [_registry setObject:componentView forKey:(__bridge id)(void *)tag];`) that were needed because NSMapTable wasn't designed for our use-case.
* Dealing with `RCTComponentViewDescriptor` which stores a pointer to a view sometimes is actually more efficient than dealing with those pointers themselfs because we can deal with `const &` to a descriptor which does not require a ref-counter bump.
* A new approach is much more flexible, it allows us to store additional data alongside view instances which we will use in coming diffs.

Summary:
In addition to already exiting method `componentViewByTag`, this diff adds a new one `findComponentViewWithTag` which does pretty much the same thing but returns `nil` in a case when it cannot find a view with a given tag. The first method now returns a non-nullable object, whereas the second (new) one return nullable.
We need this to explicitly designate call-sites that are resilient to such kind of errors, where such errors are expected because of still-existing consistency problems (because of some legacy implementation approaches).
At the same time, for the call-sites where a missing view situation is unrecoverable, we should throw early and stop paying for nullability overhead.
In the future diffs, we will change the internal implementation of the registry where the price for dealing with nullability will be actually meaningful.
This is the first diff on the road to an implementation of `RCTMountingTransactionObserving` protocol.

Summary:
The purpose of `EventBeat` is handling an asynchronous callback to itself which is being delivered on some different thread. That brings a challenge of ensuring that the `EventBeat` object stays valid during the timeframe of callback execution. The concept of Owner helps with that.
The owner is a shared pointer that retains (probably indirectly) the `EventBeat` object. To ensure the correctness of the call, `EventBeat` retains the owner (practically creating a retain cycle) during executing the callback. In case if the pointer to the owner already null, `EventBeat` skips executing the callback.
It's impossible to retain itself directly or refer to the shared pointer to itself from a constructor. `OwnerBox` is designed to work around this issue; it allows to store the pointer later, right after the creation of some other object that owns an `EventBeat`.

Summary:
Duplicate category method implementations cause undefined behavior in Objective-C; one is chosen essentially at random. The linker also issues a noisy warning about this (which is how I noticed this case).
It didn't matter in this particular case since both implementations do the same thing, but we should clean this up so people don't get desensitized to these linker warnings. There is no need to have two implementations.

Summary:
In some cases, the view class is the only that retains stored `props_` variable. At the same time the `[super updateProps:props oldProps:oldProps];` actually resets the pointer with a pointer to new props value which sometimes causes the deallocation of the old value. All that is okay unless the implementation of `updateProps:oldProps:` in superclasses stores a raw reference to an old value in the very beginning of the method (for convenience and perf reasons).
So, to prevent preliminary deallocation of the old value pointed by `_props` we moved all `[super updateProps:props oldProps:oldProps];` calls to the end of overloaded methods.

... and slighly new behaviour for one of them.
The method does nothing if given `key` already exists in the container.
This diff finishes the transition of ContextContainer from an internal bag of things with unclear yet ownership into a legit dedicated dependency injection container for the product code.
The original names of methods imply that the container can have only one object of a given type which is no longer true. The new API is much more generic and idiomatic to C++, it mimics `std:map` API which is intuitive to anyone who familiar with C++ containers.
Besides the naming, `insert` method changed the semantic a bit; now it does nothing in case of inserting an object with a key that already exists. That might seem counterintuitive for "normal" people, but C++ has some wired reasons for that and, hopefully, it's expected behavior in the C++ community.

Summary:
There was a reason why it exists: on iOS if you want to implement a view with rounded corners with a non-transparent background you need to set `clipToBounds = YES` to enabling clipping because besides drawing borders we need to clip the background otherwise it will "stick out".
There were a bunch of problems with this implementation and approach:
* It's overshooting. It applies `clipToBounds` no matter which border-radius is and no matter is there a background or not. So, it's kinda heuristic implementation and it's totally unexpected behavior sometimes.
* The previous problems can lead to performance problems as well (clipping requires additional work to do for CoreGraphics/GPU).
* The border-radius that we assigned to contentView is incorrect because it does not take border-width into account.
* This functionality only applies to non-null `contentView` which is a rear and custom case in which that can always be done manually for components that require that for some reason.

@public
In order to encapsulate property access on `YGStyle`, as a first measure we wrap all fields with accessors.
This will e.g. enable dynamic property storage and instrumentation in the future.
All accessors have a `const` version that allows direct access via `const&`. For mutation, bit fields are wrapped with a custom reference object.
This style allows for the least amount of changes in client code. Property access simply needs appended parens, eg `style.direction` becomes `style.direction`.

Seems, originally we overestimated the complexity of MountItem classes and that they ended up being notably trivial. Now, maintaining that even longer would mean paying for abstractions and allocations that we don't really need and writing a lot of tedious code.
Besides that, the one particular change that will be introduced in the coming diffs is not particularly fit very well in the existing class-based model.

Summary:
In the case where the first rootView we load enables Fabric, the UIManagerBinding ended up calling AppRegistry (JS) too early, before the bridge was fully ready. This means AppRegistry wasn't set up yet, causing redbox.
To fix this, RuntimeExecutor impl should ask the bridge to queue the callback instead of asking the MessageQueueThread directly. MessageQueueThread only works well IFF the bridge is alive, but it has no knowledge about whether the bridge is alive or not. To support this, we add `invokeAsync` impl to the RCTCxxBridge.

Summary:
Main change is to the property diffing - we now use the last known props set on the view rather than the default props to compute the diff. This requires exposing a `getProps` method on all view components which should be fine I think.
I also realized that in more complex animations with multiple nodes, the node that the animation starts on might not be connected to a view, so we don't know if it's fabric just based on that, so we have to do a recursive search through the children to find if there are any that are associated with a fabric view to decide we should start the animation immediately. Unfortunately there can still be a timing gap here since the animated API is async and the uimanager API is sync - I'll need to change the animated API to be sync to completely fix this.

Summary:
I measured the performance of UIMananger methods and found that `create` method spends a significant amount of time on preallocating views (around 10 ms on my device). Interestingly, this time was actually spent on dispatching operations on the main thread, not on performing those operations. That makes me think about think about the preallocation problem one more time.
(Here and later I discuss preemptive optimistic preallocation views on iOS, but the issues are more-less applicable for all platforms.)
BTW, what's view preallocation? – In React Native we believe that we can get significant TTI wins instantiating platform views ahead of time while JavaScript thread is busy doing reconciliation and the main one is idle.
So, seems the current approach has those downsides:
* We spend too much time on dispatching only (jumping threads, creation Objective-C blocks, managing them in GCD, incrementing atomic refcountes inside `ShadowView` and so on). That's wasteful.
* We don't have much information during preallocations that can help prepare something to save time in the future. We don't know the future size of the component, so we cannot e.g. pre-draw a border or even allocate memory for a future drawing.
* We pre-allocate to much. At the moment of component creation, we don't know will this component be filtered out by view-flattening infra or not, so we always allocate a view for it. That's ~30% more views that we actually need.
* We don't stop allocating (or dispatching instructions for that) after the recycle pool is already filled in. That's also wasteful.
Why is this so bad and how can we fix it properly?..
I thought about this problem for months. And I think the answer is trivial: We don't know the exact shape of the interface until we finish creating it, and there is no way to overcome this problem on the client side. In the ideal world, the server size (or hardcoded manifest somewhere) tells the renderer (at the moment where we started navigating to it) how many views of which type will some surface use.
And until our world is not so perfect, I think we can get a significant performance improvement doing simple preallocation of 100 regular views, 30 text views, and 30 image views during rendering the first React Native surface. So I hardcoded that.

Summary:
Right now we rely on the Paper UIManager to update animated node graphs - this hooks us into `RCTSurfacePresenter` in the same way so we are no longer reliant on Paper. Should also help with complex ordering corner cases with pre vs. post operations and restoring defaults when nodes are removed. More info:
https://github.com/facebook/react-native/pull/11819/files
Note that we don't have a way to differentiate animation nodes related to fabric views vs. paper views, so if paper and fabric are both rendering updates simultaneously it's possible they could get processed by the wrong callback. That should be very rare, rarely cause problems even if it does happen, and won't be a problem at all in a post-Paper world.

NaN/Inf is a kinda valid result of some math operations. Even if we can (and should) detect (and report early) incorrect (NaN and Inf) values which come from JavaScript side, we sometimes cannot backtrace the sources of a calculation that produced an incorrect/useless result.

For those cases, ImageRequest now exposes `ImageResponseObserverCoordinator` as a `std::shared_ptr`.
Eg, concretely in the code, `completionBlock` and `progressBlock` copied a raw pointer to the observer inside which can lead to a crash when ImageRequest is being deallocated before we received an image data.

Summary:
`RCTSurfaceHostingProxyRootView` surfaces are still automatically started right after the initialization to match `RCTRootView` interface, but `RCTSurfaceHostingView` must be started explicitly now. Also fixed some internal stuff so start and register are clear and distinct.
Background / initial motivation:
One tricky bit - we render the template as part of init`ing the rootView, so we don't know what the surfaceId will be before hand to register the UITemplate. Two possible solutions:
1) Require start be called explicitly after initializing the rootView, and setup the context in between.
2) Do something like "setUITemplateConfigForNextSurface" before creating the rootView, and have some hook when the surfaceId is assigned that associates the surfaceId with that "next" UITemplate stuff before.
(1) seems a lot cleaner, but it requires ever user of rootView to explicitly call start on it - how do you feel about that? Seems like we could also use that start call to decide if the initial render should be synchronous or not? start vs. startSync?

Summary:
Previously, we stored a pointer to ShadowNode inside NSAttributedString's attributes to make possible retrieving an EventEmitter associated with some text fragment.
That worked fine besides only one caveat: the internal implementation of NSAttributedString is quite strange and that causes a memory leak. Because of some reason, NSAttributedString does not release stored attributes after own destruction (maybe OS uses some kind of caching).
So, now, instead of storing a strong pointer to ShadowNode inside NSAttributedString, we store a weak pointer to EventEmitter. Storing a weak pointer is okay because a desired lifetime of EventEmitter is guaranteed by LocalData stored inside a View. Storing a weak EventEmitter instead of weak ShadowNode will also help us with migration to ShadowView (we cannot store ShadowView weakly because it's a stack allocated object).

Summary:
The whole mounting iOS infra now uses `ComponentHandle` instead of `std::string` as a reference to particular `ComponentView` implementation. All changes are pretty straightforward, we use a different thing/type to refer to the particular class; no changes in the logic besides a new `RCTComponentViewFactory` that serves the same role of classes registry as Objective-C runtime served previously.
That has several benefits:
* It should be slightly faster, mostly because we don't need to convert `char *` strings to `std::string` and then to `NSString *`.
* We don't need string-based component-name maps anymore (at least on this layer). We can call classes as we want and it will work because of classes are now explicit about which ShadowNodes they are compatible with.
* Most importantly, it's explicit now! That means that no runtime magic is involved anymore and we can rely on static linting tool now and not be afraid of improper code stripping/overoptimization.

Summary:
It works great on iOS, and mostly works on Android, and is now OTA'able as part of the screen config! Haven't done template view yet. One remaining issue:
Layout is borked on Android. I'm guessing the issue has to do with the timing of setting the constraints in `updateRootLayoutSpecs` and calling `mBinding.startSurface` which actually builds the shadow tree. If I try to call `updateRootLayoutSpecs` earlier, it just crashes immediately. Here's the layout it spits out, which clearly has -440 for the x of 420006, which is the RCTText component, causing it to get cut off on the left of the screen:
```

Summary:
This diff introduces a new integration concept (called RuntimeExecutor) which consolidates `Runtime` and the dispatching mechanism.
As simple as that:
`using RuntimeExecutor = std::function<void(std::function<void(facebook::jsi::Runtime &runtime)> &&callback)>;`

Summary:
This diff fixes previously broken custom border rendering.
We need a dedicated CALayer for border bitmap in order to fully support all UIView capabilities in case if some subclass uses that. Otherwise, any call of `drawRect:` method can override any content which is stored inside `contents` property of CALayer.
Q&A:
How does it work in current RN? - It does not. All `drawRect:` methods in RCTView subclasses are dysfunctional.
How does text view work in current RN? - RCTTextView does not inherit RCTView, so it does not have this problem.
How does text view support custom borders in current RN then? - It does not.

Summary:
New `ShadowTree::synchronize` method allows to perform operations on ShadowTree without a risk of an unsuccessful commit. To make it happen, the `commitMutex_` is now recursive and `synchronize` acquires it before calling the callback.
Using that we finally can implement reliable `constraintLayout`.

Summary:
Don't ask.
Really, all those descriptions from official docs like below are useless:
* `__bridge_transfer` Moves a Core Foundation pointer to Objective-C with transfer of the ownership to ARC.
* `__bridge` Transfers a pointer between Objective-C and Core Foundation with no transfer of ownership
All that is totally confusing and useless. At the end of the day, we only have to think about which additional `CFRetain` and `CFRelease` ARC will add or will not add for our pointers.
So, following official docs recommendation, we would like to add `__bridge_transfer` because of course, we do want to ARC managing the variable after we introduced it to ARC here. But we also want to have shared ownership of this. That's the key. If we use `__bridge_transfer` ARC will assume that this variable already retained once (because it exists) and will call CFRelease at the end of the scope. Right before that when we pass this variable down to call stack ARC will retain and then manage the variable according to the rest of the code. But still, from this point, we will have zero-balanced reference counter; the owning by `shared_ptr` bump is already compensated with `CFRelease` at the end of the scope. As soon as the rest of the code release the object, it will be incorrectly deallocated.
So, instead of using `__bridge_transfer` we have to use `__bridge`. That will indicate that *in this block* ARC does not manage the reference counter of the variable (which is kinda true because having `shared_ptr` inside the block already retains that) and will not add `CFRelease` at the end of the block.

Summary:
There is no need to make JS calls to start or stop React Native apps; Scheduler does it automatically. Yay!
With this change (because we have to change Scheduler API) we are starting slow process migrating away from using term `reactRootTag` when we refer to running a ReactNative app (aka Surface). We will use `surfaceId` instead. We plan to slowly and gracefully retire `reactTag` term entity replacing it with several appropriate entities specific for particular usage, e.g. `viewId` (some id which makes sense for mounting), `surfaceId`, `nodeId` (unique id representing nodes which were cloned from the original one), or `eventTarget`.

Summary:
The original design of RCTSurface implied that the Surface starts on initialization and stops on deallocation. Recently I realized that this not sufficient API in some cases when the application uses ARC with autorelease pools (that can postpone object deallocations, which is highly undesirable).
And that's simply handy to have those methods sometimes.
