Summary:
Touch cancel events are currently being ignored by the ScrollView component. Currently scrollview responds both to scroll events and touchStart/touchMove/touchEnd events.
The reason why ScrollView listens to touchStart/touchEnd is so that it can update its `state.isTouching` param. This parameter then is used in `scrollResponderHandleScrollShouldSetResponder` to make the decision if scrollview should set the responder or not. So if `isTouching` is true (we've received touchStart) then ScrollView want to became a JS responder. This in turn is important for the case where we receive scroll events that does not necessarily need to trigger responder change, e.g. we don't want Scrollview to become JS responder if scroll events have been triggered by `scrollTo` in which case setting responder would put the whole responder system in a bogus state (note that responder can be released only by touchEnd or touchCancel, so if there is no touchEnd that follows scroll event then ScrollView will remain the responder and this would break next touch interaction).
It is therefore crucial for the ScrollView to reset `isTouching` state when touchCancel arrives, as otherwise the next scroll event would incorrectly trigger responder change.
On top of that ScrollView seems to be the only component in RN's core that registers to handle touchEnd but ignores touchCancel, which stands agains the comment added to `RCTRootView.cancelTouches` [here](https://github.com/facebook/react-native/commit/c14cc123d#diff-9cd70243bd2af75c613e29972bb1b41cR127).
This problem is difficult to test with a pure RN native app, as on Android it does not surface because of the `responderIgnoreScroll` flag that is being added to every scroll event, and it essentially makes the responder system ignore scroll events so they would never trigger responder change. On the other hand on iOS the cancel events are pretty rare. With pure RN app they can only be triggered by a "system" level interaction (e.g. when system alert dialog appears or when home button is clicked and there is a touch interaction happening). This issue becomes more prominent when RN app is embedded in a more sophisticated application that may use [`RCTRootView.cancelTouches`](1e8f3b1102/React/Base/RCTRootView.h (L130)) method to block RNs gesture recognizers in some cases or with third-party libraries that deals with touch events like [react-native-gesture-handler](https://github.com/kmagiera/react-native-gesture-handler) that also calls into the method when native touch interaction is detected.

Summary:
Test suite for React Native version check relies on `ReactNativeVersion.js` file that is modified on a release branch (it contains values of a real version, not zeros).
That makes it impossible for the build to pass: https://circleci.com/gh/facebook/react-native/23494
This PR mocks it with zero values, just like we mock it in other suites. I am not sure if that is desired, but works for now.

Summary:
The core React Native codebase already has full support for CocoaPods. However, `react-native link` doesn’t play nicely with CocoaPods, so installing third-party libs from the RN ecosystem is really hard.
This change will allow to link projects that contains its own `.podspec` file to CocoaPods-based projects. In case `link` detect `Podfile` in `iOS` directory, it will look for related `.podspec` file in linked project directory, and add it to `Podfile`. If `Podfile` and `.podspec` files are not present, it will fall back to previous implementation.
**Test Plan**
1. Build a React Native project where the iOS part uses CocoaPods to manage its dependencies. The most common scenario here is to have React Native be a Pod dependency, among others.
2. Install a RN-related library, that contains `.podspec` file, with `react-native link` (as an example it could be: [react-native-maps](https://github.com/airbnb/react-native-maps)
3. Building the resulting iOS workspace should succeed (and there should be new entry in `Podfile`)

```

The return type needs to be a sub type of `id` - so scalars like `double` won't work (the bridge will crash).

Summary:
This is meant to show a possible route format for a persistent form of Yoga. Where previous layouts can remain intact while still taking advantage of incremental layout by reusing previous subtrees.
```c
YGNodeRef YGNodeClone(const YGNodeRef node);
```
The core of this functionality is a new API to clone an existing node. This makes a new detached node with all the same values as the previous one. Conceptually this makes the original node "frozen" from that point on. It's now immutable. (This is not yet enforced at runtime in this PR but something we should add.)
Since the original is frozen, we reuse the children set from the original node. Their parent pointers still point back to the original tree though.
The cloned node is still mutable. It can have its styles updated, and nodes can be inserted or deleted. If an insertion/deletion happens on a cloned node whose children were reused, it'll first shallow clone its children automatically.
As a convenience I also added an API to clear all children:
```c
void YGNodeRemoveAllChildren(const YGNodeRef node);
```
During insert/delete, or as a result of layout a set of reused children may need to be first cloned. A kind of copy-on-write. When that happens, the host may want to respond. E.g. by updating the `context` such as by cloning any wrapper objects and attaching them to the new node.
```c
typedef void (*YGNodeClonedFunc)(YGNodeRef oldNode,
YGNodeRef newNode,
YGNodeRef parent,
int childIndex);
void YGConfigSetNodeClonedFunc(YGConfigRef config,
YGNodeClonedFunc callback);
```
This PR doesn't change any existing semantics for trees that are not first cloned.
It's possible for a single node to exist in two trees at once and be used by multiple threads. Therefore it's not safe to recursively free a whole tree when you use persistence. To solve this, any user of the library has to manually manage ref counting or tracing GC. E.g. by replicating the tree structure in a wrapper.
In a follow up we could consider moving ref counting into Yoga.

Summary:
- The version check that ensures the JS and native versions match is now in its own module for two reasons: it is easier to test and it allows react-native-windows to override just this module to implement its own version check (ex: more advanced checks for RNW-specific code).
- Added unit tests for the version checking to specify its behavior more clearly, including parity between dev and prod to avoid prod-only behavior and mitigate SEVs.
- Prefixed the Obj-C `#define` with `RCT_` to conform with other RN globals.

Summary:
`Jest` allows to use fake timers and according to https://developer.mozilla.org/en-US/docs/Web/API/Window/requestAnimationFrame the return value should be `A long integer value, the request id, that uniquely identifies the entry in the callback list`. This allows to use `cancelAnimationFrame`.
In current implementation of `jest/setup.js`, the return value is undefined. Therefore it's not possible to cancel the animation frame request.
```
let id = null;
const registerCallback = (callback) => {
clearCallback();
id = requestAnimationFrame(() => {
id = null;
callback();
});
};
const clearCallback = () => {
if (null !== id) {
cancelAnimationFrame(id);
id = null;
}
};
```
```
jest.useFakeTimers();
const callback = jest.fn();
registerCallback(callback);
clearCallback();
jest.runAllTimers();
expect(callback).toHaveBeenCalledTimes(0); // Will be error in current implementation, since nothing is cleared. And test will pass, after MR is merged
```
This is fake example, but the real usage is when the animation frame request should be removed on `ComponentWillUnmount`.
