Summary: We suspect that RCTNativeAnimatedModule's conversion to TurboModule could be the cause. There could be a memory leak in the TurboModule system that RCTNativeAnimatedModule exposes, or RCTNativeAnimatedModule itself could have a memory leak. Therefore, I'm making RCTNativeAnimatedModule a regular NativeModule for now.

Summary:
There are some cases where restoring default values on component unmount is not desirable. For example in react-native-screens we want to keep the native view displayed after react has unmounted them. Restoring default values causes an issue there because it will change props controlled my native animated back to their default value instead of keeping whatever value they had been animated to.
Restoring default values is only needed for updates anyway, where removing a prop controlled by native animated need to be reset to its default value since react no longer tracks its value.
This splits restoring default values and disconnecting from views in 2 separate native methods, this way we can restore default values only on component update and not on unmount. This takes care of being backwards compatible for JS running with the older native code.
## Changelog
[General] [Fixed] - NativeAnimated - Don't restore default values when components unmount
Pull Request resolved: https://github.com/facebook/react-native/pull/26978
Test Plan:
- Tested in an app using react-native-screens to make sure native views that are kept after their underlying component has been unmount don't change. Also tested in RNTester animated example.
- Tested that new JS works with old native code

Summary:
The previous version of the code accessed `_animIdIsManagedByFabric` on the main thread (which is should be accessed on the UIManager thread) and called `flushOperationQueues` on the main thread as well (also must be called on UIManager thread because it modifies instance variables (e.g. `_operations`) which supposed to be accessed on UIManager thread).
The diff fixes that introducing an additional queue jump. That's should be fine because the overall architecture of RCTNativeAnimatedModule is appeared to be asynchronous and should be resilient to possible races.

Summary:
As part of the fix for https://github.com/facebook/react-native/issues/25349 I added `s.static_framework = true` to each podspec in repo (see https://github.com/facebook/react-native/pull/25619#discussion_r306993309 for more context).
This was required to ensure the existing conditional compilation with `#if RCT_DEV` and `__has_include` still worked correctly when `use_frameworks!` is enabled.
However, fkgozali pointed out that it would be ideal if we didn't have this requirement as it could make life difficult for third-party libraries.
This removes the requirement by moving `React-DevSupport.podspec` and `React-RCTWebSocket.podspec` into `React-Core.podspec` as subspecs. This means the symbols are present when `React-Core.podspec` is built dynamically so `s.static_framework = true` isn't required.
This means that any `Podfile` that refers to `React-DevSupport` or `React-RCTWebSocket` will need to be updated to avoid errors.
## Changelog
I don't think this needs a changelog entry since its just a refinement of https://github.com/facebook/react-native/pull/25619.

Summary:
This is my proposal for fixing `use_frameworks!` compatibility without breaking all `<React/*>` imports I outlined in https://github.com/facebook/react-native/pull/25393#issuecomment-508457700. If accepted, it will fix https://github.com/facebook/react-native/issues/25349.
It builds on the changes I made in https://github.com/facebook/react-native/pull/25496 by ensuring each podspec has a unique value for `header_dir` so that framework imports do not conflict. Every podspec which should be included in the `<React/*>` namespace now includes it's headers from `React-Core.podspec`.
The following pods can still be imported with `<React/*>` and so should not have breaking changes: `React-ART`,`React-DevSupport`, `React-CoreModules`, `React-RCTActionSheet`, `React-RCTAnimation`, `React-RCTBlob`, `React-RCTImage`, `React-RCTLinking`, `React-RCTNetwork`, `React-RCTPushNotification`, `React-RCTSettings`, `React-RCTText`, `React-RCTSettings`, `React-RCTVibration`, `React-RCTWebSocket` .
There are still a few breaking changes which I hope will be acceptable:
- `React-Core.podspec` has been moved to the root of the project. Any `Podfile` that references it will need to update the path.
- ~~`React-turbomodule-core`'s headers now live under `<turbomodule/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-turbomodulesamples`'s headers now live under `<turbomodulesamples/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- ~~`React-TypeSaferty`'s headers now live under `<TypeSafety/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511040967.
- ~~`React-jscallinvoker`'s headers now live under `<jscallinvoker/*>`~~ Replaced by https://github.com/facebook/react-native/pull/25619#issuecomment-511091823.
- Each podspec now uses `s.static_framework = true`. This means that a minimum of CocoaPods 1.5 ([released in April 2018](http://blog.cocoapods.org/CocoaPods-1.5.0/)) is now required. This is needed so that the ` __has_include` conditions can still work when frameworks are enabled.
Still to do:
- ~~Including `React-turbomodule-core` with `use_frameworks!` enabled causes the C++ import failures we saw in https://github.com/facebook/react-native/issues/25349. I'm sure it will be possible to fix this but I need to dig deeper (perhaps a custom modulemap would be needed).~~ Addressed by 33573511f0.
- I haven't got Fabric working yet. I wonder if it would be acceptable to move Fabric out of the `<React/*>` namespace since it is new? �

Test Plan:
### FB
```
buck build catalyst
```
### Sample Project
Everything should work exactly as before, where `use_frameworks!` is not in `Podfile`s. I have a branch on my [sample project](https://github.com/jtreanor/react-native-cocoapods-frameworks) here which has `use_frameworks!` in its `Podfile` to demonstrate this is fixed.
You can see that it works with these steps:
1. `git clone git@github.com:jtreanor/react-native-cocoapods-frameworks.git`
2. `git checkout fix-frameworks-subspecs`
3. `cd ios && pod install`
4. `cd .. && react-native run-ios`
The sample app will build and run successfully. To see that it still works without frameworks, remove `use_frameworks!` from the `Podfile` and do steps 3 and 4 again.
### RNTesterPods
`RNTesterPodsPods` can now work with or without `use_frameworks!`.
1. Go to the `RNTester` directory and run `pod install`.
2. Run the tests in `RNTesterPods.xcworkspace` to see that everything still works fine.
3. Uncomment the `use_frameworks!` line at the top of `RNTester/Podfile` and run `pod install` again.
4. Run the tests again and see that it still works with frameworks enabled.

Summary: Trying to mitigate animation-related crashes in T43628589. Clues: all the crashes are off the main thread, and most operations in this class happen explicitly in blocks executed on the main thread. I think there's a category of race conditions caused by animations not being allocated yet when this code runs / being deallocated as it's running. We shouldn't need to add locks if everything just runs on the main thread.

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:
Before I was looking at the animation nodeTag rather than the view reactTag to determine if it was Fabric, so sometimes we would do an early fabric flush on non-fabric views, or miss it on fabric ones.
This fixes it by associating animations with fabric based on the reactTag of the view that is associated with the animation nodeTag.

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.

Summary:
We currently rely on the Paper UIManager calling `uiManagerWillPerformMounting` to flush the animated operations queue, which includes starting and stopping animations. This mostly works right now because Fabric always starts after Paper, but sometimes Paper doesn't fire `uiManagerWillPerformMounting` for a while, which can delay an animation starting.
To fix this, I force a flush of the queues on the UIThread whenever start or stop is called. This should be safe because the order of animation operations is still preserved, and start/stop are (almost?) always called in dedicated event handler loops, so any other updates like changing the way nodes are attached should already have been processed from a previous JS execution loop.

Summary:
Not super clean, but not terrible.
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:
This PR implements the first part of [RFC0004: CocoaPods Support Improvements](353d44f649/proposals/0004-cocoapods-support-improvements.md), splitting the `React.podspec` into separate podspecs to more closely match the structure of Xcode projects.
The new structure aims to have one to one mapping between Xcode projects and podspecs. The only places where we differ from this mapping are:
* `React/React-DevSupport.podspec`: `DevSupport` is a part of `React.xcodeproj`, which corresponds to the `React-Core` pod. However, we can't include it in the `React-Core` pod because `DevSupport` depends on `React-RCTWebSocket`, which depends on `React-Core`. Pods may not have circular dependencies.
* The new pods under `ReactCommon/` don't have a corresponding `xcodeproj` because there are no `xcodproj` files in `ReactCommon/`. Those C++ modules are included in `React.xcodeproj`.
*Next steps (not in scope of this PR):*
- Start submitting the Podspecs to CocoaPods on a deploy (or turn the React Native repo into a spec repo): this is important in order to make the experience nicer for library consumers, so that it's not necessary to specify the local path of each Podspec in `Podfile`, you can just add `pod 'React', <version>`.
- Add `Podfile` to the default project template (I have a PR ready for this, but because of bugs related to subspecs, it's blocked on this PR)

Summary:
RN animations currently ignore the `Slow Animations` option on the iOS simulator because we don't use UIKit animations directly. This uses a private api to get the slow coefficient and use it in the native animated driver. We only compile the private api code on simulator so this won't cause issues for app store approval. One possible issue is that the api changes in new iOS versions but I think it's reasonable to do this.
Note that this won't work with JS driven animations, we could expose the slow coefficient as a constant and use that in JS but I decided not to implement it.

Summary:
This PR adds support for Animated tracking to Animated Native Driver implementation on Android and iOS.
Animated tracking allows for animation to be started with a "dynamic" end value. Instead of passing a fixed number as end value we can pass a reference to another Animated.Value. Then when that value changes, the animation will be reconfigured to drive the animation to the new destination point. What is important is that animation will keep its state in the process of updating "toValue". That is if it is a spring animation and the end value changes while the previous animation still hasn't settled the new animation will start from the current position and will inherit current velocity. This makes end value transitions very smooth.
Animated tracking is available in JS implementation of Animated library but not in the native implementation. Therefore until now, it wasn't possible to utilize native driver when using animated tracking. Offloading animation from JS thread turns out to be crucial for gesture driven animations. This PR is a step forward towards feature parity between JS and native implementations of Animated.
Here is a link to example video that shows how tracking can be used to implement chat heads effect: https://twitter.com/kzzzf/status/958362032650244101
In addition this PR fixes an issue with frames animation driver on Android that because of rounding issues was taking one extra frame to start. Because of that change I had to update a number of Android unit tests that were relying on that behavior and running that one additional animation step prior to performing checks.
As a part of this PR I'm adding three unit tests for each of the platforms that verifies most important aspects of this implementation. Please refer to the code and look at the test cases top level comments to learn what they do.
I'm also adding a section to "Native Animated Example" screen in RNTester app that provides a test case for tracking. In the example we have blue square that fallows the red line drawn on screen. Line uses Animated.Value for it's position while square is connected via tracking spring animation to that value. So it is ought to follow the line. When user taps in the area surrounding the button new position for the red line is selected at random and the value updates. Then we can watch blue screen animate to that position.
You can also refer to this video that I use to demonstrate how tracking can be linked with native gesture events using react-native-gesture-handler lib: https://twitter.com/kzzzf/status/958362032650244101
[GENERAL][FEATURE][Native Animated] - Added support for animated tracking to native driver. Now you can use `useNativeDriver` flag with animations that track other Animated.Values
