Summary:
It's very important in complex UIs to be able to apply alpha channel-based masks to arbitrary content. Common use cases include adding gradient masks at the top or bottom of scroll views, creating masked text effects, feathering images, and generally just masking views while still allowing transparency of those views.
The original motivation for creating this component stemmed from work on `react-navigation`. As I tried to mimic behavior in the native iOS header, I needed to be able to achieve the effect pictured here (this is a screenshot from a native iOS application):
![iOS native navbar animation](https://slack-imgs.com/?c=1&url=https%3A%2F%2Fd3vv6lp55qjaqc.cloudfront.net%2Fitems%2F0N3g1Q3H423P3m1c1z3E%2FScreen%2520Shot%25202017-07-06%2520at%252011.57.29%2520AM.png)
In this image, there are two masks:
- A mask on the back button chevron
- A gradient mask on the right button
In addition, the underlying view in the navigation bar is intended to be a UIBlurView. Thus, alpha masking is the only way to achieve this effect.
Behind the scenes, the `maskView` property on `UIView` is used. This is a shortcut to setting the mask on the CALayer directly.
This gives us the ability to mask any view with any other view. While building this component (and testing in the context of an Expo app), I was able to use a `GLView` (a view that renders an OpenGL context) to mask a `Video` component!
I chose to implement this only on iOS right now, as the Android implementation is a) significantly more complicated and b) will most likely not be as performant (especially when trying to mask more complex views).
Review the `<MaskedViewIOS>` section in the RNTester app, observe that views are masked appropriately.

Summary:
This decouples non-UI logic from RCTDevMenu into a new module RCTDevSettings.
**Motivation**: This allows developers to change dev settings without depending on the built-in dev menu, e.g. if they want to introduce their own UI, or have other devtools logic that doesn't depend on an action sheet.
It also introduces the RCTDevSettingsDataSource protocol for storing dev tools preferences. This could allow a developer to implement alternative behaviors, e.g. loading the settings from some other config, changing settings based on the user, deciding not to persist some settings, or something else.
The included data source implementation, RCTDevSettingsUserDefaultsDataSource, uses NSUserDefaults and is backwards compatible with the older implementation, so **no workflows or dependent code will break, and old saved settings will persist.**
The RCTDevMenu interface has not changed and is therefore also backwards-compatible, though
some methods are now deprecated.
In order to ensure that RCTDevSettings

Summary:
Xcode really sucks, per some discussion on e1577df1fd and https://developer.apple.com/library/content/technotes/tn2215/_index.html, if you use the headers phase, and mark headers in your static library as public, they will actually end up in the final package that's built and you can't submit to the app store! This changes our xcode setup to use a copy files phase instead.
I've also changed the header include path to be $(BUILT_PRODUCTS_DIR)/include, which is added to the include path by Xcode by default, so 3rd party libraries should not be impacted by these changes anymore.

Summary:
To make React Native play nicely with our internal build infrastructure we need to properly namespace all of our header includes.
Where previously you could do `#import "RCTBridge.h"`, you must now write this as `#import <React/RCTBridge.h>`. If your xcode project still has a custom header include path, both variants will likely continue to work, but for new projects, we're defaulting the header include path to `$(BUILT_PRODUCTS_DIR)/usr/local/include`, where the React and CSSLayout targets will copy a subset of headers too. To make Xcode copy headers phase work properly, you may need to add React as an explicit dependency to your app's scheme and disable "parallelize build".
