Summary:
Motivation:
----------
This is one of the more sought after feature requests for RN:
react-native.canny.io/feature-requests/p/add-speed-attribute-to-scrollto
This PR adds the support to add a "duration" whenever using "scrollTo" or "scrollToEnd" with
a scrollView. Currently this only exists for Android as the iOS implementation will be somewhat more involved.
This PR is also backwards compatible and does not yet deprecate the "animated" boolean. It may not make sense to ever deprecate "animated", as it could be the flag that is used when devs want the system default duration (which is 250ms for Android). I'm not sure what it is for iOS. It would simplify things to remove "animated", though.

Summary:
The snapToOffsets changes improved the flinging algorithm for snapToInterval/snapToOffsets but actually broke it for pagingEnabled because it's meant to only scroll one page at a time.
First, I just brough back the old algorithm, but noticed that it has a bunch of issues (e.g. #20155). So, I tried to improve the algorithm to make sure it uses the proper target offset prediction using the same physics model that Android uses for it's normal scrolling but still be limited to one page scrolls.
This resolves#21116.

Summary:
ScrollView always clipping children on Android even when `overflow: visible` was specified.
This change just omits the clipping during draw if `overflow: visible` is passed in.
The default is not changed (from hidden to visible) in case there is a performance impact.
Android now matches iOS in behavior. This helps with issue #21116 and resolves#14416.

This might sound against our plan of removing the RCT preffix, but it is to make it simpler to map components between current implementation of RN and Fabric (otherwise we don't know when to add the RCT preffix in Android side to find the right View Manager), later we can just remove the preffix from C++, Android, iOS and JS.

`snapToAlignment` is available on iOS but not android yet. This PR is to add support for `snapToAlignment` on android as `snapToInterval` was recently added to android and they are very useful together.
Make a `Flatlist` in android with `pagingEnabled`, `horizontal`, `snapToInterval` and `snapToAlignment` set and see how adjusting between the three values of `snapToAlignment` aligns just like it does in iOS.

Summary:
Nested scrolling in scrollViews, listViews and flatLists are enabled on iOS by default, but needs to be enabled manually on Android. This PR introduces a `nestedScrollEnabled` property to ScrollViews to support nested scrolling on Android 21 and above.
Enabling nested scroll will resolve issues with coordinator layout in android and required to support a collapsing toolbar.
Tested on the test app. We are also using this property in our app currently to support scrolling behaviour required by coordinator layouts.

Summary:
Fork and rebase of gillessed's PR https://github.com/facebook/react-native/pull/13166 which has gotten stale.
From original PR:
Motivation (required)
Multiple react native developer (including myself) have run into a crash with the react-native-photo-view library (and possibly others). The common solution to this problem lies in the underlying java code, and thus requires a change in the react native source.
The stack trace I am getting is the same as listed here alwx/react-native-photo-view#15.
There was a PR to fix this (#12085) but it was closed. In response to the comments there, in my PR, I do log the exceptions. I don't think we can get any closer to the exception because in the next level of the stack trace, we are in the android sdk code.
Looking at some stack overflow pages and the android bug tracker, it seems that this is the common solution to this bug, and does not cause any impact any functionality.
https://code.google.com/p/android/issues/list?can=1&q=pointerindex+out+of+range&colspec=ID+Status+Priority+Owner+Summary+Stars+Reporter+Opened&cells=tiles
Test Plan (required)
I have manually tested this by compiling react native android from source and have confirmed the exception still gets hit and logged, but does not cause the app to terminate.

Summary:
**Problem:**
It was observed that in [this code path](https://github.com/facebook/react-native/blob/master/ReactAndroid/src/main/java/com/facebook/react/views/scroll/ReactHorizontalScrollView.java#L292) (i.e. horizontal, paging-enabled scroll view) if you tried to programmatically call the scrollTo method within ~1s of the onMomentumScrollEnd event (which should only be called after all scrolling has ended), the scrollView would scroll to the new location, and then scroll BACK to the original location.
For example, assume you had released the scrollView at location B, and the nearest page boundary is A. Then, 1000ms later, you call scrollTo position C. The order of operations would be:
1. Begin scrolling to A from position B (as it is the nearest page boundary)
2. Reach position A
3. Fire onMomentumScrollEnd
4. 1000ms later call scrollTo C
5. scrollView scrolls to C
6. scrollView scrolls BACK to position A (for no apparent reason).
**Reason:**
I suspect this is because the [smoothlyScrollTo](https://github.com/facebook/react-native/blob/master/ReactAndroid/src/main/java/com/facebook/react/views/scroll/ReactHorizontalScrollView.java#L292) will continue to animate towards A, but the [scrollEvents will not fire](https://github.com/facebook/react-native/blob/f954f3d9b674b13977f722bc3b8dc6c1b99fe6c7/ReactAndroid/src/main/java/com/facebook/react/views/scroll/OnScrollDispatchHelper.java#L45) as they are too close to each other. So the true order of events is:
1. Begin scrolling to A from position B (as it is the nearest page boundary)
[begin smoothlyScrollTo]
[scroll towards position A]
[mActivelyScrolling is true]
2. Reach position A
[mActivelyScrolling is true]
[scroll towards position A]
[mActivelyScrolling is false, as there is another scrollEvent, but because it is close enough to the same location it is ignored]
3. Fire onMomentumScrollEnd
4. 1000ms later call scrollTo C
[scroll towards position C]
5. scrollView scrolls to C
[scroll towards position A as the original smoothlyScrollTo animation was never completed]
6. scrollView scrolls BACK to position A.
This is an untested hypothesis, but seems to explain the behavior, and the solution is more semantically correct anyway. If there is an easy way to rebuild the android binaries happy to test it myself! Just let me know!
**Solution:**
Move the mActivelyAnimating outside the mOnScrollDispatchHelper.onScrollChanged helper, because the HorizontalScrollView event should be considered to be animating so long as onScrollChanged events are being fired.

Summary:
This code related to velocity would cause some scroll events to be skipped and caused some jitter for sticky headers. Not sure if there is a better fix but removing this does fix missing events and the velocity calculation still seems to be working.
**Test plan**
Tested that sticky headers now work properly on Android, tested that velocity calculation still seem to work.
