Summary:
Adding an instrumentation endpoint that allows us to write a snapshot out to an
arbitrary output stream. This is in addition to `createSnapshotFromFile`. I
reserve the right to replace the latter with the former in a later diff.
This is necessary to allow snapshots to be requested over the chrome debugger
protocol. The protocol sends the snapshot over the wire in chunks so we need
to be able to use an output stream that can do the chunking.
Because LLVM types are not available at the JSI layer, we accept a
`std::ostream` reference which we wrap with `llvm::raw_os_ostream` within
Hermes. We should not incur the static initializer cost (or other code bloat)
of using ostreams as a result.

```

Initalizing `char const *` with a string literal in .h file makes the default constructor of the object produces different values across binary units (because a pointer to empty string can be defined differently). Now it's just a null pointer.

Summary:
ComponentName is used by many core component of React Native, such as ComponentDescriptor, ShadowNode, ShadowView and so on. In all those cases this value represents the actual name of the component which came from `concreteComponentName` template parameter of ConcreteShadowNode. In all of those cases, it's raw `char const *` type. So, we don't need to use owning representation of the string (std::string) in all those places.
The only exception from this is a part where we receive the name of the component from JS side. In this case, the source string comes from JS and has to be analyzed as a character sequence to find corresponding ComponentDescriptor.
In my experiments, 20% of the time during diffing is spent on copying (this) `std::string`.

Summary:
This diff reimplements the prop parsing infrastructure in a part where it interacts with RawProps value.
Local synthetic tests show that the new way is 3x faster but the actual production result is quite unpredictable. MobileLab tests show some improvements about 10-20 ms on iPhone 6.
In short, the new way is faster because it inverts the lookup order and heavily relies on actual data types (and their properties) that we use. The old approach required about 130 hash-map lookups (where the key is `std::string`) to parse a single *Props object.
The new approach prepares concrete-props-specific tables with indexes of coming values ahead of time, iterates over raw data and puts it into those tables, and then performs a lookup in a very efficient manner.

Besides that, the future, more sophisticated optimization will rely on this.

... 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.
Fun fact: We need this to fix hot-reload.

While we don't have a real *production* use cases where we need compilation for desktops, having CXX target is really handy for two reasons:
* It simplifies local test running process. Instead of going to `/fbandroid/` and executing something like `buck test fbsource//xplat/js/react-native-github/ReactCommon/fabric/core:coreAndroid` (note the suffix). We can just do `buck test fbsource//xplat/js/react-native-github/ReactCommon/fabric/core:core` everywhere and it works now out of the box. Running tests with "Apple" flavor never worked for me.

This method when checking if bundle is a RAM bundle, uses `JniJSModulesUnbundle::isUnbundle` which only check for js-modules/UNBUNDLE - file generated when building File RAM bundle. There is no other logic to handle Indexed RAM bundle, so it figures that the bundle is not RAM, cause there is no js-modules/UNBUNDLE file and tries to load as regular bundle and fails.
In this PR we added check if it is indexed RAM bundle in `jniLoadScriptFromAssets` and handle it if it is.

Summary:
Replace the *copy on write* vector with an atomic pointer to a linked list.
This allows to publish without locking a mutex, at the cost of the slower traversal of a linked list (a vector has better locality).
At the moment, the typical use case is to have one subscriber, meaning that the afforementioned slower traversal is not a problem.
Adding subscribers is implemented as atomic *compare and swap.*

Summary:
We currently have two different codepaths for actually rendering a surface with Fabric on iOS and Android: on iOS we use Fabric's `UIManagerBinding.startSurface` to call `AppRegistry.runApplication`, but on Android we don't; instead we use the same codepath as paper, calling `ReactRootView.runApplication`.
This diff does a few different things:
1. Unify iOS and Android by removing the `#ifndef` for Android so that we call `startSurface` for both
2. Pass through the JS module name on Android so that this actually works (it currently passes in an empty string)
3. Remove the call to `ReactRootView.runApplication` for Fabric so that we don't end up doing this twice
4. Copy over some logic that we need from `ReactRootView.runApplication` (make sure that root layout specs get updated, and that content appeared gets logged)

Summary:
This diff restores the original role of StateData as a dummy class that has only one purpose - designate that there is no state associated with the node.
I believe having an abstract StateData class for all data types is not necessary and actually slightly harmful. And here the reasons:
* Having virtual dispatch enabled for classes introduces some overhead, and it should be used only if it is absolutely necessary. In this case, we don't need to have virtual dispatch enabled for Data classes because it's already enabled for State classes; therefore all virtual resolution is done there and that's sufficient. No need to pay for what we don't need.
* Continuing the previous point, yes, we expect some API being exposed for Data classes (such as `getDynamic`), but introducing a base abstract class for that is *not* an idiomatic C++ solution; in C++ it's by design that most of the template contracts are actually duck-typed. This is a well-known design issue/concern that will be addressed with an effort called "Concepts" in C++20. Anyway, we should not use abstract classes as *only* indication of conformance to some interface.
* StateData does not introduce any convenience. As it is clear from several subclass implementations, we don't really use base methods from it.
* The previous issue actually happens especially because of the interface of StateData class. Consider constructor that accepts `folly::dynamic` and does nothing, it actually useless because it's impossible to use it unless it's called inside superclass's constructor. That's the case because C++ does not support virtual dispatch for constructors (for good).
* Avoiding subclassing StateData counter-intuitively enforces the desired conformance to imaginary interface: it does not compile otherwise.

Summary:
With the introduction of TurboModules, it would be beneficial to measure the setup time of these modules, as we currently have it in place for NativeModules.
The instantiation of the TMs occurs in the `RCTTurboModuleManager`. In order to successfully measure the time it took to setup the module, we need to ensure that we don't take into account cached modules. As such, we need to:
1. Check if module is in `_turboModuleCache`
a. Start mark for `RCTPLTurboModuleSetup` tag if not found
2. Get the TM via `[self provideTurboModule:]`
3. Check if module is in `_turboModuleCache`
a. Stop mark for `RCTPLTurboModuleSetup` if we did not find module in cache prior to **step 2** and if it's now present in the cache.
b. Notify about setup time if the above is true.
4. Return TM
## Changelog
[iOS] [Added] - Gain insights on the the turbo module setup times by observing `RCTDidSetupModuleNotification`. The userInfo dictionary will contain the module name and setup time in milliseconds. These values can be extracted via `RCTDidSetupModuleNotificationModuleNameKey` and `RCTDidSetupModuleNotificationSetupTimeKey`.

std::shared_ptr<TurboModule> getTurboModule(std::string name, std::shared_ptr<JSCallInvoker> jsInvoker) override;
```
On the C++ side, when asked to provide a TurboModule with name `name`:
1. First, is this a CxxModule? If so:
1. Create the CxxModule and return
2. Otherwise:
1. Somehow get a Java instance of the TurboModule
2. If this Java object represents a CxxModule, like `FbReactLibSodiumModule`:
1. Grab the C++ part of this object, and wrap it in a `TurboCxxModule.cpp` and return.
3. Otherwise:
1. Wrap the Java object in a C++ HostObject and return.
This pseudocode demonstrates how we'd use `TurboModuleManagerDelegate` to implement `__turboModuleProxy`.
```
__turboModuleProxy(name, jsCallInvoker):
let cxxModule = TurboModuleManagerDelegate::getTurboModule(name, jsCallInvoker)
if (!cxxModule) {
return cxxModule;
}
// JNI Call that forwards to TurboModuleManagerDelegate.getLegacyCxxModule
let javaCxxModule : CxxModuleWrapper = TurboModuleManager.getLegacyCxxModule(name)
if (!javaCxxModule) {
return std::shared_ptr<react::TurboCxxModule>(javaCxxModule.getModule())
}
// JNI Call that forwards to TurboModuleManagerDelegate.getModule
let javaModule : TurboModule = TurboModuleManager.getModule(name)
if (!javaCxxModule) {
return TurboModuleManagerDelegate::getTurboModule(name, javaModule, jsCallInvoker)
}
return null

Summary:
JSCallInvoker requires a `std::weak_ptr<Instance>` to create. In our C++, `CatalystInstance` is responsible for creating this `Instance` object. This `CatalystInstance` C++ initialization is separate from the `TurboModuleManager` C++ initialization. Therefore, in this diff, I made `CatalystInstance` responsible for creating the `JSCallInvoker`. It then exposes the `JSCallInvoker` using a hybrid class called `JSCallInvokerHolder`, which contains a `std::shared_ptr<JSCallInvoker>` member variable. Using `CatalystInstance.getJSCallInvokerHolder()` in TurboModuleManager.java, we get a handle to this hybrid container. Then, we pass it this hybrid object to `TurboModuleManager::initHybrid`, which retrieves the `std::shared_ptr<JSCallInvoker>` from the `JavaJSCallInvokerHandler`.
There were a few cyclic dependencies, so I had to break down the buck targets:
- `CatalystInstanceImpl.java` depends on `JSCallInvokerHolderImpl.java`, and `TurboModuleManager.java` depends on classes that are packaged with `CatalystInstanceImpl.java`. So, I had to put `JSCallInvokerHolderImpl.java` in its own buck target.
- `CatalystInstance.cpp` depends on `JavaJSCallInvokerHolder.cpp`, and `TurboModuleManager.cpp` depends on classes that are build with `CatalystInstance.cpp`. So, I had to put `JavaJSCallInvokerHolder.cpp` in its own buck target. To make things simpler, I also moved `JSCallInvoker.{cpp,h}` files into the same buck target as `JavaJSCallInvokerHolder.{cpp,h}`.
I think these steps should be enough to create the TurboModuleManager without needing a bridge:
1. Make `JSCallInvoker` an abstract base class.
2. On Android, create another derived class of `JSCallInvoker` that doesn't depend on Instance.
3. Create `JavaJSCallInvokerHolder` using an instance of this new class somewhere in C++.
4. Pass this instance of `JavaJSCallInvokerHolder` to Java and use it to create/instatiate `TurboModuleManager`.
Regarding steps 1 and 2, we can also make JSCallInvoker accept a lambda.

Luckily, it does not need a complex feature-full map (which is not free to allocate and use), it needs a tiny map with a dozen values. Why do we need to pay for what we don't use?

Previously we computed the list of nodes that need to be notified about layout changes using a list of mutation instructions. That was fine, but that's not really compatible with some other changes that I plan to make, so I decided to change it (make it better).
Besides the better design (debatable; fewer dependencies to unrelated moving pieces), here is why I believe the new way is more performant:
* The new approach has no `dynamic_casts`, whereas the previous has tons of them (two per a mutation). If a `dynamic_cast` takes 10 ns, for 500 nodes it can take up to 5ms only for casts. (Non-scientific assumption.)
* After removing dependency to mutation instruction, we can enable flattening for views which have `onLayout` event.

Summary:
Different frameworks use different kinds of floats, optional floats, and floats with assigned unit names. All those approaches use different ways to represent undefined and empty values. To deal with it we need to have some helper functions.
So, this diff changes some ways that we convert some corner values (like NaN and empty value). That change is motivated by recent personal discoveries in this field that shifted my vision on that. E.g. ComponentKit does not use `CGFloatMax` value as `Infinite` value. UIKit is also (surprisingly to me) okay with using `Infitite` instead of `CGFloatMax`. And, in general, seems using really conceptually appropriate values (instead of UIKit-inspired ones) it's the right thing to do.

At the same time usage of `kFloatMax` was replaced with `Infinity` (which is a different value). Using `max` instead of `Infinity` was an attempt to mimic iOS/UIKit model where `Infinity` and `NaN` values usually are not being used. However, now this does not seem like a good idea. This concept is not used anywhere else (even in CK which is totally incompatible with it) and de-facto in RN we use it only in few places. So, let's use Infinity in places where it's logically appropriate.

Adds `YGStyle::ValueRepr` to make code depending on the actual type easier to write.
So far, we have treated `yoga::detail::CompactValue` as an implementation detail, and that’s what it’s supposed to stay.
React Native Fabric has one value conversion overload that depends on that type, though, and used `decltype(YGStyle{}.margin()[0])` until now.
That’s problematic for two reasons:
- we want to constrain the parameter of `operator[](...)` to enum types, making the `0` unsuitable
- we want to return the non-const overload of the operator to return a custom `Ref` type, which is not the type needed by Fabric.
Making the storage type explicit allows to write more forward-compatible code.

Summary: This installs the sample module to the RNTester.xcodeproj without using any TurboModule infra. This is possible because SampleTurboModule is backward compatible with the existing NativeModules system. This also fixes CI test failure: https://circleci.com/gh/facebook/react-native/84752

Summary:
Motivation:
* We don't use them much, and we already have `at`-methods, which are better.
* We don't want to expose `ComponentDescriptor`s as shared pointers (because it's not clear, not so performant, and because we don't want to store them as shared pointer in the future);
* In idiomatic C++ `[]` operator has mutating semantic, that's not what we want to communicate via the interface of the class.

Summary:
If you call into a Java method (from C++ using JNI) that raises an exception, the JNI call won't actually raise a C++ error. Instead, the `JNIEnv` will record the pending Java exception and the C++ will continue executing as normal. This is bad because the next time you call into JNI, the app will actually crash, unless you explicitly cleared the exception using `JNIEnv::ExceptionClear()` before the JNI call.
With respect to TurboModules, we need to make sure that RedBoxes show up whenever a native methods raise an exception. We also don't want the app to crash when a JNI method call fails because of a raised exception. Therefore, in this diff, I raise a C++ exception if `JNIEnv::ExceptionCheck()` is true.

Summary:
If the return type of a TurboModule method is `Promise`, the infra should create a `com.facebook.react.bridge.Promise` object and pass it as the final argument of the TurboModule Java method call. The Java TurboModule method can then do some work asynchronously and either resolve or reject the promise at some point in time.
**Note:** I stacked a diff for error handling on top of this one.

Summary:
Turns out that storing and using ContextContainer in custom subclasses is a huge pain. At the same time seems that a lot of custom components need some DI instrument, so we need this instrument anyway.
Moving stuff from the template to the base class should also help with codesize a bit.

Summary:
@public
This allows short methods defined in class declarations to occupy a single line.
The change makes class declarations more readable.

Summary: This sets up RCTSampleTurboModule (and other variants) in RNTester when built with cocoapods. There's no call site yet though. And RNTester.xcodeproj doesn't support it.

Summary:
This provides various versions of SampleTurboModule, that are:
* compatible with existing NativeModule
* TurboModule compliant
Variants:
* RCTSampleTurboModule (traditional objc module)
* RCTSampleTurboCxxModule (objc++ module using CxxModule)
* SampleTurboModule (pure C++ impl of a TurboModule, no ObjC)
As noted in some files, they need to be codegen'ed based on the `NativeSampleTurboModule.js` (Flow type). The codegen script is not yet usable in OSS (we'll work on it some time in H2 2019). For now, these files need to be manually synced with Flow type.
