Previously, to fix the issue of commands happening before the Views

had not been mounted to a View, to update its hierarchy. In reality, we need
to do this irrespective, since a node could be mounted to a View, but its
children may not yet be attached, for example. Note that if there is nothing
to be done, this won't do extra work (i.e. applyUpdates recursively goes

but if there are no updates, we stop traversing that praticular subtree).

- Handle MeasureMode correctly, previously AT_MOST was not supported.
- Better handling of RTL text by using TextLayoutBuilder where I made changes to support RTL text in components. Specifically RTL text measured with UNSPECIFIED or AT_MOST.

This adds support for specifying multiple sources for an image component, so that native can choose the best one based on the flexbox-computed size of the image.
The API is as follows: the image component receives in the `source` prop an array of objects of the type `{uri, width, height}`. On the native side, the native component will wait for the layout pass to receive the width and height of the image, and then parse the array to find the best fitting one. For now, this does not support local resources, but it will be added soon.
To see how this works and play with it, there's an example called `MultipleSourcesExample` under `ImageExample` In UIExplorer.

With nodes, it's possible for a touchable region to not be
explicitly mounted to a View. To work around this (and allow the region to
be the handler of the touch event), FlatViewGroup intercepts touch events
when the touch lies within any of the virtual NodeRegions.
This can sometimes be wrong - the canonical example is when touch starts
outside of a particular FlatViewGroup (so someone else, for example a
sibling) intercepts the touch event, and then the person moves over a
different FlatViewGroup, causing it to intercept the touch event when it
shouldn't. To fix this, we only allow intercepting touch events due to
NodeRegions on the down event.

b) flush the views-to-drop queue. This works, but does some extra work in UI thread (namely, removing Views that would be removed anyway)

This diff changes the logic so that overflow can be set on any node (image, text, view etc).
The change has an important implication that make the diff a little trickier that it could be: AbstractDrawCommand clipping logic needs to be relaxed. Previously, clip bounds were *always* intersected with node bounds, which means that clip rect was always within node rect. This is no longer true, and thus shouldClip() logic needs to be modified.
Because of the above, RCTText no longer needs to artificially clip bounds against layout width/height.
Note: RCTImage is still not working with overflow: visible correctly (it still always clips). This is fixed in a follow up diff.

Summary:
There is an assert in FlatViewGroup.reactTagForTouch() that says that TouchTargetHelper should not allow returning getId() when pointer events are BOX_NONE. This is not entirely accurate.
This acturally method is invoked in 2 different contexts. Main context is to find a touch target, and in that context the method indeed should never return getId() if pointer events are BOX_NONE. There is however a TouchTargetHelper which actually expects that reactTagForTouch() *may* return getId(), in which case it will perform logic to not all this method be invoked again from main context.
In other words, this assert needs to be removed because it is entirely possible to return getId() when pointer events are BOX_NONE. Ideally, these would be 2 different methods, but ReactCompoundView interface only defines a single reactTagForTouch() method.

Summary:
Nodes create a FlatViewGroup for a root node element, and NativeViewHierarchyManager assigns it an id that matches root node it. Now this top-level FlatViewGroup is added to a ReactRootView. In non-nodes, this ReactRootView has an id that matches root View id, and when this ReactRootView gets detached from Window, it sends an event to NativeViewHierarchyManager that says that all the children of this View must be removed recursively. This works great in non-Nodes, but fails in Nodes because ReactRootView has no id (-1) and NativeViewHierarchyManager fails to find a corresponding ReactShadowNode, throwing an Exception. To fix the issue and make it work again we need to assign this View id of the top level shadow node. This creates a minor issue, where 2 Views (ReactRootView and its only child) share the same id, but that is not a problem because we don't enforce uniqueness of the ids, and don't rely on getViewById().
This was originally implemented, but then I removed it because I thought it wasn't truly needed. Turns out, it is needed.

When mounted to a View, TextNodeRegion will have a bounds of (0,0,width,height) which is clearly different from (left,top,right,bottom). Initially I assumed they would always be the same so we could use information stored in NodeRegion (should probably be called TouchRegion) to update node's View boundaries, but it breaks RCTTextView when it mount to a View (because it would either contain incorrect bounds, or View will be laid out incorrectly). Right now touch is not working on RCTView that mounts to a View. To fix the issue, separate the 2 concepts.

Summary:
Everything (but Views) are drawn using AbstractDrawCommand (or its derivative, like DrawBorder or DrawBackgroundColor) and supports clipping properly. Views however are drawn using an assumption that Android will clip them manually. This is however not always true. One example is if an element A mounts to a View, and its parent B doesn't but has overflow: hidden and thus should clip the child.
There are 2 ways to fix this:
- pop every element that has overflow: hidden to its own View. In this case, its children will always be correctly clipped. This is however very inefficient, especially if overflow: hidden is default (which it is!) which means that almost every React element must be backed by an Android View.
- add clipping information to DrawView, similar to how AbstractDrawCommand has it.
This diff implements the latter approach.

This is obviously not correct, because no matter how rare these events are, they actually happen in practice. This diff re-implements manageChildren() to support all the cases. It does so by first removing all the elements that need to be removed. During removal, those elements that need to be moved will be temporarily put into `mNodesToMove` array. Then the next step is to add all elements (including new elements to add, and existing elements to move). There is an fast path when only one of another is present. If both types are present, they need to be sorted, first, to maintain correct orded. A similar optimization is applied to `removeChildren()`: there is a fast path when moveFrom == null and a another fast path when removeFrom == null. When both are != null, a merge sort is used (it is assumed that both moveFrom and removeFrom are sorted).

Summary:
In ReactNative, we are fully controlling layout of all the Views, not allowing Android to layout anything for us. This is done by making onLayout() of the top-level View in the hierarchy to be empty. This works fine because we explicitly call measure/layout for all the Views when they need to be re-measured or re-laid out. There is however one case where this doesn't happen automatically: some Android Views such as DrawerLayout or ActionBar have children that don't have shadow nodes associated with them (such as a title in ActionBar). This results in situations where children of AndroidView will call requestLayout but they will never get relaid out, because shadow hierarchy doesn't know about them. Example: ActionBar has a seTitle method that will internally call TextView.setTitle() and that TextView will call requestLayout because its size may have changed. However, that TextView will never be remeasured or relaid out.
This diff is fixing it by keeping track of everyone who called requestLayout. Then, at the end of the update loop we go over the list a manually remeasure and relayout those Views.
Not a huge fan of how this is implemented (there MUST be a better way) but this works with least efforts. I'll see if I can improve it later.

b) there is already logic in place to drop Views (NativeViewHierarchyManager.dropView(int reactTag) - used to private but needs to be protected so I can call it)
c) (the missing part) when we are about to drop a FlatShadowNode, check if it mount to a View (i.e. there is a View associated with that node), put it into a ArrayList. When we finished updates to a nodes hierarchy (which happens in non-UI thread), collect ids from those nodes and enqueue a UIOperation that will drop all the Views. We can either forward nodes as FlatShadowNode[], or only ids as int[]. Both should be fine, but as a rule of thumb we don't touch shadow node hierarchy from UI thread (as we don't touch Views from non-UI thread) so passing int[] is what this code is doing.

Summary:
An exception is thrown when the native animation code attempts to play an animation on a view that hasn't been created yet. This can happen because views are created in batches. If this particular view didn't make it into a batch yet, the view won't exist and an exception will be thrown when attempting to start an animation on it.
This change eats the exception rather than crashing. The impact is that the app may drop one or more frames of the animation.

I'm not familiar enough with the Android native animation code to know whether or not this is a good fix. My team is using this change in our app because dropping animation frames is better than crashing the app. [This is the code](c612c61544/ReactAndroid/src/main/java/com/facebook/react/uimanager/UIViewOperationQueue.java (L874-L892)) that is creating the views in batches.

Summary:
Android has a text API called breakStrategy for controlling how paragraphs are broken up into lines. For example, some modes support automatically hyphenating words so a word can be split across lines while others do not.
One source of complexity is that Android provides different defaults for `breakStrategy` for `TextView` vs `EditText`. `TextView`'s default is `BREAK_STRATEGY_HIGH_QUALITY` while `EditText`'s default is `BREAK_STRATEGY_SIMPLE`.
In addition to exposing `textBreakStrategy`, this change also fixes a couple of rendering glitches with `Text` and `TextInput`. `TextView` and `EditText` have different default values for `breakStrategy` and `hyphenationFrequency` than `StaticLayout`. Consequently, we were using different parameters for measuring and rendering. Whenever measuring and rendering parameters are inconsistent, it can result in visual glitches such as the text taking up too much space or being clipped.

Summary: This changes ReactImageView to pull the transform matrix for rounding from the scale type itself instead of a utility method that forwards to the same thing.

Summary:
The goal of this pull request is to make it easier for contributors to run Android tests locally, specifically the unit tests and integration tests. I added a bunch of checks to the local testing scripts that will warn you if your environment is misconfigured, and tell you how to fix it. I also updated the testing docs, so that the regular "Testing" page should be a decent resource to point people to when you are telling them "hey this pull request needs a test." Just Android, though, I haven't gotten to the iOS parts yet.
I also disabled a couple tests that seemed quite flaky while running on a local machine, and don't seem to be providing much value. In particular, the `TestId` test just hangs on my emulator a lot and has been flaky on CI in the past, so I removed about half of its test cases to make the sample app smaller. The testMetions test appears to be dependent on screen size so I commented it out.

Summary:
Currently any React Native apps that target API 23 or greater will crash on the first initial debug/dev build due to the overlay permission.
Sadly there isn't a concrete "request permission" baked into the Marshmallow permission system.
However, we can launch the overlay screen without starting the react app and once its turned on start the app.
- https://github.com/facebook/react-native/issues/10454 - targetSdkVersion 23 lead crash / App crash for targeting 23+
- https://github.com/facebook/react-native/pull/10479 - Add the overlay permission information / Larger discussion around targeting API 23+
- Intent to Overlay permission goes directly to the app in question, rather then the general full listing of applications. This allows a developer who is not familiar with the system to easily toggle the overlay without getting confused.

* Ran UIExplorer App on fresh install with Target 23

Summary:
By default Android will put extra space above text to allow for upper-case accents or other ascenders. With some fonts, this can make text look slightly misaligned when centered vertically.
We have found that the effect is very noticeable with certain custom fonts on Android. On iOS the font aligns vertically as expected.
Android exposes a property `includeFontPadding` that will remove this extra padding if set to false. This PR exposes that to JS, and adds it to the documentation and UIExplorer.

Summary:
This PR fixes#11096.
I don't know enough the ReactAndroid's source code so I don't know if this is correct but I hope it is.
In a recent commit (d4b8ae7a8a), the `dispatchUpdates` method now returns a boolean to dispatch or not the `onLayout` event. This works well but if the content is unchanged, the line `nativeViewHierarchyOptimizer.handleUpdateLayout(this);` is never called. I don't know if it was intended but it was this which introduces my issue. I called this again even if the content didn't change. This was the behaviour before 0.38 so I guess I didn't break anything.
**Test plan (required)**
I tested my pretty big app with this fix and every screen is ok.

Summary:
Suppose that the user is scrolled to the bottom of a ScrollView. Next, the ScrollView's content is edited such that the height of the content changes and the current scroll position is larger than the new height of the content. Consequently, the user sees a blank ScrollView. As soon as the user interacts with the ScrollView, the ScrollView will jump to its max scroll position.
This change improves this scenario by ensuring that the user is never staring at a blank ScrollView when the ScrollView has content in it. It does this by moving the ScrollView to its max scroll position when the scroll position after an edit is larger than the max scroll position of the ScrollView.
Here are some pictures to illustrate how this PR improves the scenario described above:

Summary:
ReactAndroid/build.gradle downloads a number of ad-hoc dependencies from the internet such as boost, JSC headers, and folly. Having the build depend on the internet is problematic. For example, if the site hosting the JSC headers was to go down, then CI builds would start failing.
This change introduces the environment variable REACT_NATIVE_DEPENDENCIES which refers to a path. Developers can pre-download all of the ad-hoc dependencies into that path and then the build process will grab the dependencies from that local path rather than trying to download them from the internet. This solution is in the spirit of the existing REACT_NATIVE_BOOST_PATH hook.

Summary:
Made modification to react-native code that reduces the communication channel overhead to ~50% of prior, in some cases, by caching the class-name of the java-script module/interface.
For me it reduced the run-time of the RCTDeviceEventEmitter.emit function from 1438ms to 715ms, over a period of 8 seconds in my Android app. My project requires many emit calls, as I'm transferring real-time EEG data from a Muse headband to my react-native UI to be graphed, so this optimization was very helpful in my case.
