Summary:
This provides a way to customize the return type of a sync exported method, instead of just using `id`.
```
RCT_EXPORT_SYNCHRONOUS_TYPED_METHOD(NSString *, sync1:(NSString *)x)
{
return @"hello";
}
```
The return type needs to be a sub type of `id` - so scalars like `double` won't work (the bridge will crash).

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:
Queues Problem Intro:
UIManager queue is special queue because it has special relationship with
the Main queue.
This particular relationship comes from two key factors:
1. UIManager initiates execution of many blocks on the Main queue;
2. In some cases, we want to initiate (and wait for) some UIManager's work *synchronously* from
the Main queue.
So, how can we meet these criteria?
"Pseudo UIManager queue" comes to rescue!
"Pseudo UIManager queue" means safe execution of typical UIManager's work
on the Main queue while the UIManager queue is explicitly blocked for preventing
simultaneous/concurrent memory access.
So, how can we technically do this?
1. `RCTAssertUIManagerQueue` is okay with execution on both actual UIManager and
Pseudo UIManager queues.
2. Both `RCTExecuteOnUIManagerQueue` and `RCTUnsafeExecuteOnUIManagerQueueSync`
execute given block *synchronously* if they were called on actual UIManager
or Pseudo UIManager queues.
3. `RCTExecuteOnMainQueue` executes given block *synchronously* if we already on
the Main queue.
4. `RCTUnsafeExecuteOnUIManagerQueueSync` is smart enough to do the trick:
It detects calling on the Main queue and in this case, instead of doing
trivial *synchronous* dispatch, it does:
- Block the Main queue;
- Dispatch the special block on UIManager queue to block the queue and
concurrent memory access;
- Execute the given block on the Main queue;
- Unblock the UIManager queue.
Imagine the analogy: We have two queues: the Main one and UIManager one.
And these queues are two lanes of railway go in parallel. Then,
at some point, we merge UIManager lane with the Main lane, and all cars use
the unified the Main lane.
And then we split lanes again.
This solution assumes that the code running on UIManager queue will never
*explicitly* block the Main queue via calling `RCTUnsafeExecuteOnMainQueueSync`.
Otherwise, it can cause a deadlock.

Summary:
If you are a product developer and you need to fix your app's issues related to iPhone X limitations asap,
you can temporary use `DeviceInfo.isIPhoneX_deprecated`.
You can, but you should not. Please consider use new <SafeAreaView>.
This prop was initially named so ugly because we are trying to discourage the community to use it.
However, we understand that sometimes we need a "band-aid" to prevent our apps bleeding.
Note: This prop (DeviceInfo.isIPhoneX_deprecated) will be removed completely after 06/18.

Summary:
This fixes [#15801](https://github.com/facebook/react-native/issues/15801)
We ran into a strange crash on iOS (debug only). After removing the clutter I was able to reproduce it in a tiny app. You can check it out [here.](https://github.com/simonracz/textinput_stress)
The UI in JS and native are not always in sync (which is okay). Due to this, a native view might call back into JS, which is no longer present in the shadow view hierarchy there. I think this should be also okay.
TextInput in some cases calls into [setIntrinsicContentView](6d67e2dbbc/React/Modules/RCTUIManager.m (L382)), where it triggers an overly enthusiastic `NSAssert` and crashes the app.
Check out [textinput_stress](https://github.com/simonracz/textinput_stress)
Rotate the simulator a few times to see the crash or the lack of crash.

Summary:
This is required for D5874536, wherein I'll be introducing direction-aware props for borders.
When a view's border changes due to a direction update, only the frames of its children update. Therefore, only the children `UIView`s get a chance to be re-rendered. This is incorrect because the view that's had its borders changed also needs to re-render. So, I keep a track of the layout direction in a property on all shadow views. Then, when I update that prop within `applyLayoutNode`, I push shadow views into the `viewsWithNewFrames` set.

Summary:
Basic implementation of the proposal in #15271
Note that this should not affect facebook internally since they are not using OSS releases.
Points to consider:
- How strict should the version match be, right now I just match exact versions.
- Wasn't able to use haste for ReactNativeVersion because I was getting duplicate module provider caused by the template file in scripts/versiontemplates. I tried adding the scripts folder to modulePathIgnorePatterns in package.json but that didn't help.
- Redscreen vs. warning, I think warning is useless because if the app crashes you won't have time to see the warning.
- Should the check and native modules be __DEV__ only?
**Test plan**
Tested that it works when version match and that it redscreens when versions don't before getting other errors on Android and iOS.

Summary:
This issue has been open for a really long time, but I'm pretty sure this is the line that needed to change:
https://github.com/facebook/react-native/issues/1831
What was happening here is that `CGRectIsEmpty` returns true when either height or width is zero. With the current logic, one of those would always be zero when the parent was rendered off screen. This ensures that there the intersection be of CGSizeZero for the view to actually be clipped.
That being said, there seems to be something more complex going on here that I'm not understanding? I would think that you'd simply want to check if the child view's frame is within the bounds of the parent at all. If it was, then don't clip it. If I'm in the wrong, could someone explain this a bit more? If so, I'll fix this issue.
Using this [repository](https://github.com/jcharlet/react_native_listview_bug), this one line change fixes the issue and still clips cells as they are scrolled off screen.
