Summary:
There was some missing super.__detach calls in some Animated nodes, we rely on the base class being called to drop the node in the native implementation, not doing so will cause some nodes to leak. It also resulted in a crash when removing certain nodes because they would get updated after being detached.
**Test plan**
Reproduced the crash by unmounting a view that uses a DiffClamp node and made sure this fixes it. Also tested that other native animations still worked properly.

Summary:
Delay was broken with native animations on iOS. After checking what android does to handle delay, I noticed it does nothing at all since the delay is already handled when generating the animation frames. This removes all code that tried to handle delay on iOS since it is not needed and breaks it. Also updated an example to have delay in UI explorer.
Fixes#12388
**Test plan**
Tested that delay works in UIExplorer on iOS and Android.

Summary:
Need to make sure `detach` happens on the old `scrollableNode` before it's unmounted and that `attach` happens on the new `scrollableNode` after it's mounted. This should also be more performant because the detach step no longer requires iterating through all the props, most of which are not animated, and we filter out unneeded updates if props or ref haven't changed.
= Test Plan =
Hook up native onscroll events in `FlatListExample` and toggle "debug" - before, the events would stop working because they would try to attach to the old unmounted node, but with this diff it keeps working as expected.

Summary:
* Any animation can be looped on the javascript thread
* Only basic animations supported natively at this stage, loops run
using the native driver cannot contain animations of type sequence,
parallel, stagger, or loop
Motivation: We need a spinner in our app that is displayed and animated while the javascript thread is tied up with other tasks. This means it needs to be offloaded from the javascript thread, so that it will continue to run while those tasks are churning away.
I originally submitted PR #9513, which has served our needs, but brentvatne pointed out a better way to do it. Had hoped his suggestion would be implemented by janicduplessis or another fb employee, but after 5 months I thought I'd give it another push.
I've put together an implementation that basically matches the suggested API. Let me know what you think, and whether others can pick it up from here and get it in to core.

Fixes a bug that happens when trying to use ScrollView with sticky headers and native `Animated.event` with `onScroll`. Made a few changes to the ListViewPaging UIExplorer example to repro https://gist.github.com/janicduplessis/17e2fcd99c6ea49ced2954d881011b09.
What happens is we need to be able to add multiple events to the same prop + viewTag pair. To do that I simple changed the data structure to `Map<prop+viewTag, List<AnimatedEventDriver>>` and try to optimize for the case where there is only one item in the list since it will be the case 99% of the time.

Summary:
This re-implements sticky headers in JS to make it work on Android.
The only change that was needed was to expose a way to attach a an animated value to an event manually since we can't use the Animated wrapper and `Animated.event` to do it for us because this is implemented directly in the `ScrollView` component. Simply exposed `attachNativeEvent` that takes a ref, event name and event object mapping. This is what is used by `Animated.event`.
TODO:
- Need to check why momentum scrolling isn't triggering scroll events properly on Android.
- Remove native iOS implementation
- cleanup / fix flow

Summary:
After taking a look at the existing animation docs, I found that most of the documentation on using `Animated` was spread out throughout the Animations guide and the `Animated` API reference, without any particular structure in place.
This PR aims to clean up the API reference, focusing on documenting all the provided methods exhaustively, and deferring to the Animations guide for long form examples and supporting content.
The `Easing` module is referred to at various points in the API reference, so I decided to clean up this doc as well. easings.net provides some handy visualizations that should make it easier for the reader to understand what sort of easing curve each method provides.
The site was built locally, and I verified all three documents render correctly.

Summary:
findNodeHandle is considered an internal module. The one to use is ReactNative.findNodeHandle. We need to rely on this because we will have two different renderers and we need the renderers to inject themselves with findNodeHandle before it is used.
I use ReactNative.findNodeHandle from inside the module because I think this leads to a cycle somewhere or might not play well with inline require otherwise.
There is also one in UIManager but that is definitely a cycle so I'm going to try to avoid that one.

Summary:
The `extractOffset` method is previously implemented on `Animated.Value`, along with `setOffset` and `flattenOffset`. Both of the latter methods are proxied on `Animated.ValueXY`, but `extractOffset` is not. This commit adds the missing method.
When creating draggable elements in XY space, in order to compensate for previous gestures' offsets, we currently need to do something like the following at the beginning or end of each gesture:
```
xy.setOffset(xy.__getValue());
xy.setValue({x: 0, y: 0});
```
After this commit, the API is equivalent to using a plain `Animated.Value`:
```
xy.extractOffset();
```

Summary:
On iOS, when you press down native fading components, they become
transparent instantly, but then have an animated fade in/out if you
move your finger in/out of their hit box.
On react-native currently, the touchdown fades, instead of providing
instant feedback, which doesn't feel right on iOS.
I'm less familiar with Android conventions, but it seems to use fading
components for buttons less often, instead using the ripple effect from
TouchableNativeFeedback. In either case, instant feedback seems better
for the user.

Summary:
`flattenOffset` has proven extremely useful, especially when dealing with pan responders and other gesture based animations, but I've also found a number of use cases for the inverse. This diff introduces `extractOffset`, which sets the offset value to the base value, and resets the base value to zero. A common use case would be to extractOffset onGrant and flattenOffset onRelease.

Summary:
Native Animated.Value uses the value it was created with when sending the config to native but this causes issue when the value has changed before calling `__makeNative` this happens with the `progress` value for `NavigationExperimental`. It gets initialized with value 1, then uses `setValue` to change it to 0 before starting the animation and this is when `__makeNative` is called. This simply uses the current value instead of the value passed to the constructor. Also pass offset so native implementations that support it can use it (iOS).
**Test plan**
Tested that the first transition that uses the `progress` animated value is not broken in an app that uses `NavigationExperimental` when using `useNativeDriver` for animations.

Summary:
Combining 2 animated values via addition, multiplication, and modulo are already supported, and this adds another one: division.
There are some cases where an animated value needs to invert (1 / x) another animated value for calculation. An example is inverting a scale (2x --> 0.5x), e.g.:
```
const a = Animated.Value(1);
const b = Animated.divide(1, a);
Animated.spring(a, {
toValue: 2,
}).start();
```
`b` will then follow `a`'s spring animation and produce the value of `1 / a`.
The basic usage is like this:
```
<Animated.View style={{transform: [{scale: a}]}}>
<Animated.Image style={{transform: [{scale: b}]}} />
<Animated.View>
```
In this example, the inner image won't get stretched at all because the parent's scaling gets cancelled out.
Also added this to native animated implementation.

Summary:
This adds support for `Animated.event` driven natively. This is WIP and would like feedback on how this is implemented.
At the moment, it works by providing a mapping between a view tag, an event name, an event path and an animated value when a view has a prop with a `AnimatedEvent` object. Then we can hook into `EventDispatcher`, check for events that target our view + event name and update the animated value using the event path.
For now it works with the onScroll event but it should be generic enough to work with anything.

Summary:
see also: eb3360b02a (commitcomment-19042340)
commit eb3360b02a recently break some third libraries that was (weakly) relying on traversing `animatedNode.refs.node` to get the original node of the decorated (animated) component (at least 2 libs: gl-react-native and react-native-material-kit).
Instead of now doing `animatedNode._component` (that might later break again), getNode() is a more 'public' solution for these third party.
as you expose a way to create an animated component (`createAnimatedComponent`) you sometimes still want a way to get the reference.
That way, third party components can continue providing some extra native methods to the animated version.
