Summary:
In React Native there are several use cases where React State is not the only input that affects the component tree. E.g., in case of a <Modal> component, the screen size directly affects the layout of components inside modal; in the case of uncontrolled <TextInput> component, the text inside the input affects the layout of the surrounding components. `State` is a special (legit!) workaround for all those similar cases. Native part of React Native maintains a special shared object between all nodes of the same family and use that during cloning and commits.
See coming commits to know how to use that.
In the near future State will fully replace LocalData concept but for simplicity they both exist for now.

Unfortunately this still relies on the old Paper UIManager calling delegate methods to flush the operations queues. This will work for Marketplace You since Paper will be active, but we need to fix this, along with Animated Events which don't work at all yet.
Random aside: it seems like taps are less responsive in fabric vs. paper, at least on iOS. There is a sporadic delay between the touches event coming in nativly to the JS callback invoking the native module function to start the animation - this will need some debugging.

Summary:
Sometimes, when we deal with ImageRequest and ImageResponseObserverCoordinator we subscribe for status (or access the coordinator) without owning an ImageRequest. In those cases, we have to retain the coordinator explicitly.
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.

- Make the codebase more portable;

- Make relying on modern C++ patterns and tools in code simple and easy.
- Make executing experiments with different dependencies easier.

Summary:
Our long-term plan is to completely illuminate `jsi::Value`-to-`folly::dynamic` serialization step in prop parsing process improving performance and memory pressure. At the same time, we don't want to introduce a hard dependency in application code to JSI because it exposes direct access to VM and prevents parsing some data that come *NOT* from JSVM.
RawValue is an extremely light-weight (hopefully fully optimized-out) abstraction that provides limited JSON-like and C++-idiomatic interface.
The current particular implementation is still using `folly::dynamic` inside, but I have fully JSI-powered one which will replace the current one right after we figure out how to deal with folly::dynamic-specific callsites. Or we can implement RawValue in a hybrid manner if a code-size implication of that will be minimal.

Summary:
For some time we have had a nit trick inside `EventEmitter`: When event emitter is disabled, we switch to store `EventTarget` as a weak pointer instead of complete deleting it. Given some unpredictability of JS GC, it gave us some time to restore the pointer in case if we increment the counter right after decrementing this. Apparently, we found that it doesn't always work (obviously, sigh...), so we implement the `enableCounter_` and left this feature as it is assuming that it can nice optimization that illuminates some unnecessary constraints.
But, apparently, it's actually harmful, assuming that `jsi::WeakObject` (that thing that we use to refer to actual JS target) actually has "unsafe unretained" (not "weak") semantic.
So, we have to remove this.
This change will be particularly important for coming diffs in the stack.

This diff fixes a race condition that was detected on "Marketplace You" production test for Android.
The race condition happens when the method ShadowTree::complete is executed concurrently from two threads (in this case this is called from Scheduller::constraintSurfaceLayout and Scheduler::uiManagerDidFinishTransaction), based on the order of execution this bug makes MountViewItems to be dispatched to the UI in the wrong order.
The root cause of the bug is in the method:
```
bool ShadowTree::complete(
const SharedRootShadowNode &oldRootShadowNode,
const UnsharedRootShadowNode &newRootShadowNode) const {
newRootShadowNode->layout();
newRootShadowNode->sealRecursive();
auto mutations =
calculateShadowViewMutations(*oldRootShadowNode, *newRootShadowNode);
if (!commit(oldRootShadowNode, newRootShadowNode, mutations)) {
return false;
}
emitLayoutEvents(mutations);
if (delegate_) {
delegate_->shadowTreeDidCommit(*this, mutations);
}
return true;
}
```
Notes:
- the commit method is guarded by the commitMutex_
- the shadowTreeDidCommit() method dispatches mutations instructions to the platform side.
- If there are two threads running concurrently, there is no guarantee that the shadowTreeDidCommit() is going to be called in the correct order.
The solution is to include the execution to shadowTreeDidCommit() in the same commitMutex_
Possible solutions:
1 - move the commitMutex_ out of the commit method (to the completeMethod)
2 - synchronize the call to complete method() - this is the implemented solution.
I chose this solution to make it consistent with the way Scheduler::constraintSurfaceLayout is implemented (https://fburl.com/8l49no5x)
This mechanism is very likely to change in the refactor of threading mechanism that Valentin Shergin is going to be working on January.
I would like to land this, so we can fix this bug and run another experiment in production as soon as possible.

`YGFloatOptional::getValue()` has the unfortunate property of calling `std::exit` if the wrapped value is undefined.
That forces `x.isUndefined() ? fallback : x.getValue()` as access pattern.

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:
Consider this:
* ParagraphShadowNode retains LocalData,
* LocalData contains AttributedString,
* AttributedString contains Fragments,
* Fragment can contain a pointer to parent shadow node, so it can be the ParagraphShadowNode.
In this case it's a retain cycle.
We actually don't need to store pointers to not TextShadowNodes, so we don't now.
Later, after we fully migrate to ShadowView, we can remove this condition because it will become harmless.

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:
```
updateLayoutMountItem for reactTag: 420006 x: -440, y: -13, width: 931, height: 78

Summary:
* Adds parent tag as param for createNode in place of explicit appendChild commands.
* Adds version info to bytecode
* Adds native conditional support:
Conditionals are represented in product code with the new `NativeConditional` React
component. It takes params necessary to construct a native function call, and takes
a render prop as a child that passes the value of the native call as an arg. In
prod, the component would actually call the native module and render with that value,
but in jest we render for *both* true and false and set them as children
of a new jest-only primitive/host component which we special-case and generate a
special command with `OP_CODE.conditional`, generate the appropriate bytecode commands
for each branch, and embed them as args in the conditional OP_CODE command. When
evaluating the bytecode, only one set of commands is executed, based on the native
module value (which is evaluated with another new opcode which computes the value
and stuffs it in a "register").
Obviously generating this bytecode is kind of a cludge compared to prepack, but
when I asked @[501709947:Dominic] about it, he said they had no bytecode spec right
now, so I'm running ahead with this prototype. The main thing I'm focused on is
the C++/RN bytecode interpretter - this jest stuff is just a way to generate bytecode
for it to consume which could be replaced or augmented with many other approaches,
such as prepack, server rendering, etc.
Also piggybacked a bunch of other cleanup.

Summary:
A bunch of different things was changed, but the most important (and need) change is that `UIManager` is now passed in the function as a regular reference, not as a `shared_ptr`. Besides that fact that passing this as `shared_ptr` is simply incorrect (because there is no ownership sharing/transferring here), we need this change because we cannot construct `shared_ptr` from `this` inside `UIManager` class (especially in the constructor).
Besides that:
* `const &` everything (correctness, explicit intention, performance);
* Names were unified with the rest of the code;
* `auto` everything;
* All JSI stuff is now explicitly prefixed with `jsi::`;
* `using` instead of `typedef` (modern C++ syntax);

Summary:
The spec says that `bridge_transfer` indicates that we "transfer ownership of the pointer" to ARC which implies that as soon this part of the code does not need the object, it will be deallocated. However, that's not what we want here. This object is actually already owned by another ARC-powered code somewhere else and the pointer to it was transferred as a raw pointer through the C++ world.
So, we want to keep the ownership of the object on the other side but still imply the lifetime of the object. So how can we do that? Simple, we have to use `bridge`.
Why? ARC is not magical, it's just automatic ref counting. And I think the only difference between `bridge` and `bridge_transfer` is how many refcounter's bumps will be added to the generated code. In the case of `bridge_transfer` it is zero, in the case of `bridge` it is one. So, initializing a new Objective-C variable that points to the shared resource we have to bump the counter once, so we have to use `bridge`.

Summary:
As we did in the previous diff, here we implemented `EventEmitter`'s ownership model as a `shared_ptr`. This change fixes problem with leaking `WeakObject`s which happens on hot-reload.
So, in short:
* `EventTargetWrapper` object owns `jsi::WeakObject` that can be converted to actual `jsi::Object` that represent event target in JavaScript realm;
* `EventTargetWrapper` and `jsi::WeakObject` objects must be deallocated as soon as native part does not need them anymore;
* `EventEmitter` objects retain `EventTarget` objects;
* `EventEmitter` can loose event target object in case if assosiated `ShadowNode` got unmounted (not deallocated); in this case `EventEmitter` is loosing possibility to dispatch event even if some mounting-layer code is still retaining it.

Summary:
Previously, we used special JSI bindings method to release an event handler (`JSIReleaseFabricEventHandler`). Now we expose this ownership model as a regular `std::shared_ptr`, so when the owner got deallocated, the event handler will be released automatically.
Why not use `unique_ptr`? `unique_ptr` is faster (and simpler) indeed, but it does not provide `type erasure` functionality that we need; to use `unique_ptr` we would have to make JSI an explicit Fabric dependency (we will probably end up with it eventually, but I this particular case is not a good reason for that).
All interactions with `eventHandler_` are done in a non-owning manner, so it's as performant as unique_ptr anyway.
(Please ignore all changes in JSCFabricUIManager.h/cpp files, we will delete them soon.)

Summary:
This diff includes two changes:
1. `TextShadowNode` represents virtual texts. For the time being, virtual text nodes only need touch capabilities so that they can handle `onPress` events for their children. Therefore, we should set the `TextShadowNode`'s `EventEmitterT` to `TouchEventEmitter`.
2. Since `ParagraphShadowNode` extends an instance of the `ConcreteViewShadowNode` template, it automatically uses the `ViewEventEmitter` if no event emitter is specified. I think it's better to make the event emitter explicitly specified. So, I've included that change in this diff.

Summary:
When a user clicks on some text, `RCTSurfaceTouchHandler` will call into a method on `RCTParagraphComponentView`. That method (i.e: `touchEventEmitter`) would be responsible for identifying the closest ancestral `<Text/>` component to which we should dispatch the `onPress` event, given the point where the user clicked. To answer this query, we'll use a data structure called `UIAttributedString`.
This data structure represents a string, and a corresponding mapping from sequences of its characters to some arbitrary data. In this attributed string, we'll map sequences of characters to their closest ancestral `ParagraphShadowNode` or `TextShadowNode`. That way, when we get a click event on `RCTParagraphComponentView`, we can just look at the character that was clicked, and use that information to do a lookup in the attributed string to find the shadow node who's EventEmitter is responsible for processing the click event.

Summary: Previously, `BaseTextShadowNode::getAttributedString` used to recurse on a list of `SharedShadowNode`s (i.e: the children). In the `RawText` base case of this recursion, we'll need to record the parent of the current `RawText` (so that we can dispatch the `onPress` event to it). Therefore, we need to start recursing using the `SharedShadowNode` itself, and not its children.

Now we simply skip `uiManagerDidFinishTransaction` calls if they refer to unregister surfaces. In the future, after we have proper asynchronous scheduling and sync unmounting (and if we chose to have sync unmounting), we can avoid this situation (and assert in this cases).

Previously, we amitted `default` argument in `convertRawProp` functions assuming that all default values are equal to results of their default constructors (which was something between "wrong" and "lucky coincidence"). Now we use a `YGStyle` default value as a source of all semantic default values of all layout props/styles.

Now it's clear that we don't need to store/handle ShadowTree objects as `shared_ptr`s; Scheduler should own it. This diff changes that to using unique_ptr and removes a base class of ShadowTree.

Voalá, this small change actually implements view flattening. Obviously, it does not work right now because there are no `ShadowNode` classes which implement `isLayoutOnly`.
Surprisingly, correct implementing of `isLayoutOnly` is quite tricky, we will work on this in coming diffs.

Summary:

This is quite a big diff but the actual meaningful change is simple: now we use ShadowView class instead of ShadowNode in mutation instructions.
Note:
* In some places (especially during diffing) we have to operate with ShadowNodeViewPair objects (which represents a pair of ShadowNode and ShadowView). The reason for that is that we cannot construct child ShadowViews from parent ShadowViews because they don't have any information about children.
* `ShadowTree::emitLayoutEvents` is now much simpler because ShadowView better represents the specifics of this kind of object.
* The code in RCTMountingManager also became simpler.
This change will allow us to implement more cool tricks soon.

Summary:

We need some another object like ShadowNode (but not ShadowNode) to represent an instance of the component in the mutation instructions. This is
the main motivation for introducing ShadowView.
Why not use ShadowNode? ShadowNode is designed to represent a node in ShadowTree, not be a part of a mutation instruction.
* ShadowNode exposes some APIs that should not be exposed to the mounting layer;
* ShadowNode is an immutable data structure, so we cannot mutate it in some way which can be meaningful for mounting;
* We should not add to ShadowNode any functionality which is needed only for mounting;
* ShadowNode is a bit more heavy object to share that it needs to be; it's exposed (embedded into Mutation) as a `shared_ptr` which is not optimal from the performance perspective;
* Retaining ShadowNode from mounting code can unnecessarily extend its lifetime which can negatively affect memory usage.

Summary: This diff implements the HorizontalScrollView component for Android Fabric C++, as part of this diff I also re-named the components AndroidHorizontalScrollContentView for RCTAndroidHorizontalScrollContentView and AndroidHorizontalScrollView for RCTAndroidHorizontalScrollView. This might sound against our plan of removing the RCT preffix, but it is to make it simpler to map components between current implementation of RN and Fabric (otherwise we don't know when to add the RCT preffix in Android side to find the right View Manager), later we can just remove the preffix from C++, Android, iOS and JS.
