Summary:
When false, ScrollView disables use of pinch gestures to zoom in and out. This allows ScrollView's pinch gesture responder to be disabled to only allow zooming programmatically. The default value is ~false~ true.
**Test Plan**
Tested that pinch gesture responder is disabled when pinchEnabled=false.

Summary:
In iOS11, Apple added a new layout feature called "Safe Areas" (this blog post talks a bit about it: https://www.bignerdranch.com/blog/wwdc-2017-large-titles-and-safe-area-layout-guides/).
UIScrollView is one component that is affected by this change in Apple's API. When the `contentInsetAdjustmentBehavior` is set to `automatic`, for example, it will adjust the insets (and override any manually set insets) automatically based on whether or not there's a UINavigationBar, a UITabBar, a visible status bar, etc on the screen. Frustratingly, Apple decided to default to `Automatic` for this behavior, which will cause any apps that set contentInset/contentContainerStyle padding to have their values offset by, at the very least, the size of the status bar, when they compile their app for iOS 11. Here's more information about this behavior: https://developer.apple.com/documentation/uikit/uiscrollview/2902261-contentinsetadjustmentbehavior?language=objc
Mostly, this is a really straightforward change -- it simply adds a new iOS-only prop to ScrollView that allows setting `contentInsetAdjustmentBehavior`. But I did decide to default the behavior to `never`, so that it mimics the behavior we've seen in iOS < 11. I think it's good to keep something as crucial as scrollview content insets non-magical, and also keep it behaving similarly between platforms.

Summary: Optimize ScrollView by adding flag "DEPRECATED_sendUpdatedChildFrames" to gate whether updatedChildFrames data is computed and propagated on scroll events. The frame data is used in ListView by the onChangeVisibleRows prop. When this prop is not defined, unnecessary computation in ScrollView should not be performed.

Summary:
Flashing scroll indicators is a standard behavior on iOS to show the user there's more content.
Launch RNTester on iOS, go to the ScrollView section, tap the "Flash scroll indicators" button.
You'll see this:
![Flash scroll indicators](https://cloud.githubusercontent.com/assets/57791/26250919/ebea607a-3cab-11e7-96c6-27579cc809ab.gif)
I've exposed the method `flashScrollIndicators` on all scrolling components that were already exposing a `scrollToXXX` method so it's usable from those components using a ref.
Let me know what you think.

Summary:
Remove the native iOS sticky headers implementation that has been replaced by the js Animated one. Also remove a line in JS that made sure we passed null to native so it did not use the native implementation.
**Test plan**
Made sure there were no more mentions of sticky / header in native ScrollView related code.
Tested that sticky headers still work :o

Summary:
Motivation: reduce build noise that might worry new users or hide real problems.
This deals with four of the warnings currently in the iOS build. The `__unused` additions are standard and self-explanatory, following the style used elsewhere in RN. I've used `#pragma unused` to deal with parameters named by macros.
Tested by building and running the `UIExplorer` example app in XCode 8.2

Summary:
This fixes measuring of items in the main axis of a container. Previously items were in a lot of cases measured with UNSPECIFIED instead of AT_MOST. This was to support scrolling containers. The correct way to handle scrolling containers is to instead provide them with their own overflow value to activate this behavior. This is also similar to how the web works.
This is a breaking change. Most of your layouts will continue to function as before however some of them might not. Typically this is due to having a `flex: 1` style where it is currently a no-op due to being measured with an undefined size but after this change it may collapse your component to take zero size due to the implicit `flexBasis: 0` now being correctly treated. Removing the bad `flex: 1` style or changing it to `flexGrow: 1` should solve most if not all layout issues your see after this diff.

Summary:
Removes the deprecated APIs that were replaced by `RefreshControl`. Those API have been deprecated for a while already so I think it's fine to remove them at this point. Also ported the `SwipeRefreshLayoutTestModule` test to use `RefreshControl` instead of `PullToRefreshViewAndroid`.
**Test plan (required)**
Made sure no references are left in the codebase to `PullToRefreshViewAndroid`, `onRefreshStart` and `endRefreshing`.
Tested that `ScrollView` examples in UIExplorer still work properly.
Check that the `SwipeRefreshLayoutTestModule` passes on CI.

This diff deprecates `scrollResponderScrollWithoutAnimationTo` and replaces it with an optional `animated` param in `scrollResponderScrollTo`. This is more consistent with our other APIs.
Using the old `ScrollResponder.scrollResponderScrollWithoutAnimationTo` or `ScrollView.scrollWithoutAnimationTo` functions will still work, but will trigger a warning.

Summary:
Our events all follow a common pattern, so there's no good reason why the configuration should be so verbose. This diff eliminates that redundancy, and gives us the freedom to simplify the underlying mechanism in future without further churning the call sites.
Summary:
The bridge implementation on React Android does not currently support boxed numeric/boolean types (the equivalent of NSNumber arguments on iOS), nor does Java support Objective-C's nil messaging system that transparently casts nil to zero, false, etc for primitive types.
To avoid platform incompatibilities, we now treat all primitive arguments as non-nullable rather than silently converting NSNull -> nil -> 0/false.
We also now enforce that NSNumber * objects must be explicitly marked as `nonnull` (this restriction may be lifted in future if/when Android supports boxed numbers).
Other object types are still assumed to be nullable unless specifically annotated with `nonnull`.
Summary: At the moment the `ListView.js` `_childFrames` variable is only updated on scroll. As a consequence, `onChangeVisibleRows` won't get triggered for the initial render, nor any future render not trigered by scroll events. To fix this we need to make sure native and JS have the child frames in sync.
Summary:

I've increased the warning levels in the OSS frameworks, which caught a bunch of minor issues. I also fixed some new errors in Xcode 7 relating to designated initializers and TLS security.
Test Plan:
* Test the sample apps and make sure they still work.
* Run tests.
