Summary:
When using the packager behind something like an http tunnel it is possible something else than JS is returned, in that case throw an error instead of trying to parse it.
This is useful for Expo since the packager runs behind ngrok. This allows to intercept that error and show a more meaningful error message based on the ngrok response.
**Test plan**
Tested by changing the packager to return text/html content type and validate that the error shows up properly.
Also tested that it works when multipart response is disabled.

Summary:
Surprisingly enough, even if semantically the code remains identical, layouting via autoresizing masks applies changes to subviews a bit earlier than iOS calls `layoutSubviews`.
This allows us to avoid situations where we already explicitly set calculated by Yoga frames and want to scroll to some subview, but actual layout have not done yet and internal views has wrong frames.

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:
**Motivation**
This is a re-worked version of #14260, by shergin's suggestion.
For iOS, if you want to inherit from a native ViewManagers, your custom ViewManager will not automatically export the parents' props. So the only way to do this today, is to basically copy/paste the parent ViewManager-file, and add your own custom logic.
With this PR, this is made more extensible by exporting the `baseModuleName` (i.e. the iOS `superclass` of the ViewManager), and then using that value to re-establish the inheritance relationship in `requireNativeComponent`.
**Test plan**
I've run this with a test project, and it works fine there. But needs more testing.
Opened this PR as [per shergin's suggestion](https://github.com/facebook/react-native/pull/10946#issuecomment-311860545) though, so we can discuss approach.
**Discussion**
* Android already supports inheritance, so this change should be compatible with that. But, not every prop available on `UIManager.RCTView.NativeProps` is actually exported by every ViewManager. So should `UIManager.RCTView.NativeProps` still be merged with `viewConfig.NativeProps`, even if the individual ViewManager does not export/use them to begin with?
* Does this break other platforms? [UWP](https://github.com/Microsoft/react-native-windows)?

Explain the **motivation** for making this change. What existing problem does the pull request solve?
The problem occurs when a ScrollView's content height is smaller than the ScrollView height. If the method `scrollToEnd` is called on the ScrollView, it will pull the content down until the bottom of the content is aligned with the bottom of the Scrollview container.
This fix will ensure the proper functionality: That the furthest the ScrollView can scroll down is to where the top of the content container is at the origin (i.e., the ScrollView scroll number cannot be less than 0).
Prefer **small pull requests**. These are much easier to review and more likely to get merged. Make sure the PR does only one thing, otherwise please split it.
**Test plan (required)**
Demonstrate the code is solid. Example: The exact commands you ran and their output, screenshots / videos if the pull request changes UI.
Make sure tests pass on both Travis and Circle CI.
I tested on a scenario where the ScrollView is almost the full size of the screen, and the content of the ScrollView has a height of much less. In this situation, the `scrollToEnd` method was executed and the content stayed in the same position. This is the intended behavior. If the content of the ScrollView is smaller than the height of the ScrollView, then the `scrollToEnd` method should not scroll anywhere.
**Code formatting**
Look around. Match the style of the rest of the codebase. See also the simple [style guide](https://github.com/facebook/react-native/blob/master/CONTRIBUTING.md#style-guide).

That's interesting!
If we apply `display: none;` style to some node, Yoga will stop calculation layout for this subtree (which is reasonable).
So, from RN perspective we have to stop applying layout for hidden subtree because it is meaningless and causes another errors.
Note: We do actually not support `display: none;` yet. It stops computing layout, but it does not hide the views!

Summary:
This change introduces some APIs that are useful for making announcements through the screen reader on iOS:
- `announceForAccessibility`: The screen reader announces the string that is passed in.
- `announcementFinished`: An event that fires when the screen reader has finished making an announcement.
You can already solve similar problems with RN Android using the `accessibilityLiveRegion` prop. Live regions are a different feature but they can be used to solve the same problem. This commit does not attempt to add live region support in RN iOS because Apple did not build live region support into iOS.
Verified that `announceForAccessibility` causes VoiceOver to announce the string when VoiceOver is enabled. Verified that `announcementFinished` fires with the appropriate data in the event object. Additionally, my team has been using this change in our app.

RCTUIManager.sendAccessibilityEvent(

Summary:
In some cases, `RCTRecursiveAccessibilityLabel` could return an accessibility label that had leading space, trailing space, or multiple spaces between words. This is because it always added a space before adding a label even if the label turned out to be empty.
This is fixed by being stricter about adding spaces.
Found test cases that used to introduce leading space, trailing space, or multiple spaces between words and verified that there aren't any extra spaces after the fix.
```
{/* Used to have leading space */}
<View accessible={true}>
<View />
<View accessibilityLabel='Two' />
<View accessibilityLabel='Three' />

{/* Used to have 2 spaces between "One" and "Three" */}
