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.

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.

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.

Summary:
The `FrescoModule` supports providing a custom image pipeline configuration. This module is created by `MainReactPackage` but `MainReactPackage` doesn't expose any way to customize the Fresco configuration. This change adds a parameter to `MainReactPackage`'s constructor so that the `FrescoModule`'s configuration can be customized by the app. A couple of design choices were made in this change:
- `MainReactPackage`'s new constructor parameter is a `MainPackageConfig`. Introducing `MainPackageConfig` enables `MainReactPackage` to nicely support new optional configuration options in the future. Imagine the alternative of each optional configuration being a separate parameter to the `MainReactPackage` constructor.
- `FrescoModule` exposes its default configuration as a builder object through the `getDefaultConfigBuilder` method. This enables app's to start with `FrescoModule`'s default configuration and then modify it.

Summary:
When using text inputs inside a ScrollView with `keyboardShouldPersistTaps=false` (default behavior) tapping another text input dismisses the keyboard instead of keeping it open and focusing the new text input which I think is the better and expected behavior.
See #10628 for more discussion about that. Note that this affects nothing but the behavior with text inputs unlike #10628.

Summary:
This PR removes dependency to Jackson third-party library in Android React Native.
Looking at some older PRs that got merged, it seems like some work had already been done to move away from Jackson.
Anyway, there was only two classes left with a dependency on Jackson. I refactored the code to use android built-in `JsonReader` and `JsonWriter` classes instead.
Prep work was done in https://github.com/facebook/react-native/pull/10516 introducing a few unit tests around serialization, to make sure that refactoring around serialization would not break things.
All references to Jackson in build systems files (BUCK files & build.gradle) have also been removed now that no code depend anymore on this third-party library.
Motivation behind this work is that third-party dependencies in Android React Native can prove to be a pain when trying to integrate React Native components into an already existing large Android application (I know this is not the most common use case for react-native ... yet ;P), that might a

Summary:
On Android, if there is a small amount of space available around a text input (e.g. landscape orientation on a phone), Android may choose to have the user edit the text inside of a full screen text input mode. This behavior isn't always desirable. For example, if your app offers some UI controls for controlling the formatting of the text, you want the controls to be visible while the user is editing the text. This Android feature conflicts with that desired experience because the UI controls would be hidden while the text is being edited.
The `disableExtractUI` prop enables developers to choose whether or not Android's full screen text input editing mode is enabled. When this prop is true, Android's `IME_FLAG_NO_EXTRACT_UI` flag is passed to the `setImeOptions` method.
**Test plan (required)**
Verified `disableExtractUI` works for both `true` and `false` values in a test app.

Summary:
Virtual shadow nodes (e.g. text) don't use CSSNodes so we don't need to create them. This shows large savings in CSSNodes allocated, depending on the app.
This could be breaking if:
- You have virtual nodes that still set and get CSS properties. The setters now no-op for virtual nodes (I unfortunately couldn't remove them completely -- see the comment on LayoutShadowNode), but the getters will NPE. If you see these NPE's, you should almost definitely be using your own datastructure instead of a CSSNode as virtual nodes will not participate in the layout process (and the CSSNode is then behaving just as a POJO for you).
I do not anticipate this to be breaking for anyone, but am including breaking in the commit message since this is a change in API contract.

For example, if you have the link "something://example/" but your device doesn't have anything to handle the "something" scheme, the app would crash when the user clicks on the link. This change handles the exception to prevent the app from crashing. Instead, the click is a no-op and the WebView doesn't navigate anywhere.

Summary:
The only callsite of `coalesce` looks like this:
```
newEvent.coalesce(oldEvent);
```
The default `coalesce` implementation returns the event with the most recent timestamp. When the events have the same timestamp then, using the variable names from above, `coalesce` returns `oldEvent`.
This change updates `coalesce`'s implementation to make it explicit that it returns `this` (`newEvent` in the variable names from above) in the case of a tie.
The motivation for this change is related to scroll events. In my team's app, we were seeing scroll events being emitted with the same timestamp and the coalescing logic was causing the oldest scroll event to be chosen. This was causing our JavaScript code to receive stale scroll information and the way the JavaScript code utilized this stale scroll information resulted in the ScrollView settling on the wrong scroll position.

TextInput rounds padding down with `floor` when measuring. However, it rounds padding up with `ceil` when rendering.
This change makes things consistent by moving TextInput's rendering code to use `floor` as well. It looks like this is the intended behavior because commit bdff10b moved measuring from `ceil` to `floor`. It looks like TextInput's rendering code was just overlooked in that commit.

Summary:
Moves from CSSNodeDEPRECATED to CSSNode. This has shown to be a huge performance win for layout time within FB.
This is BREAKING because CSSNode contains bug fixes that were not migrated to CSSNodeDEPRECATED which may change the way your layout appears. The most common of these by far involves `flex: 1`.
Previously, developers had to put `flex: 1` in many places it didn't belong in order to work around a bug in css-layout. Now `flex: 1` is treated properly and, unfortunately, this means that your layout may no longer look correct. Specifically, you may see that your layout looks collapsed, or children don't render. The fix is to simply remove `flex: 1` from those containers.
