Summary:
Because it is not simply flushing, it (in the future) is more complex process. And the names should represent logical meaning of the process, not particular implementation details.
It also nice to have unified terminology across our reactive UI frameworks.

Trivial change.

Summary:
RCTSurface instance represents React Native-powered piece of a user interface
which can be a full-screen app, separate modal view controller,
or even small widget. It is called "Surface".
The RCTSurface instance is completely thread-safe by design;
it can be created on any thread, and any its method can be called from
any thread (if the opposite is not mentioned explicitly).
The primary goals of the RCTSurface are:
- ability to measure and layout the surface in a thread-safe and synchronous manner;
- ability to create a UIView instance on demand (later);
- ability to communicate the current stage of the surface granularly.

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:
In some cases we need a way to specify some environmental data to shadow view
to improve layout (or do something similar), so `localData` serves these needs.
For example, any stateful embedded native views may benefit from this.
Have in mind that this data is not supposed to interfere with the state of
the shadow view.

Summary:
On an iPhone running iOS 10.3.3, I'm not seeing the UIContentSizeCategoryDidChangeNotification fire when changing the system's font scale setting. Registering for the event on `nil` instead of on the application object fixes the issue.
**Test Plan**
Verified that text in an RN app changes size when you change the system's font scale setting (Settings -> General -> Accessibility -> Larger Text). By default, RN text is supposed to scale with the system setting.
