Summary:
This PR adds support for Animated tracking to Animated Native Driver implementation on Android and iOS.
Animated tracking allows for animation to be started with a "dynamic" end value. Instead of passing a fixed number as end value we can pass a reference to another Animated.Value. Then when that value changes, the animation will be reconfigured to drive the animation to the new destination point. What is important is that animation will keep its state in the process of updating "toValue". That is if it is a spring animation and the end value changes while the previous animation still hasn't settled the new animation will start from the current position and will inherit current velocity. This makes end value transitions very smooth.
Animated tracking is available in JS implementation of Animated library but not in the native implementation. Therefore until now, it wasn't possible to utilize native driver when using animated tracking. Offloading animation from JS thread turns out to be crucial for gesture driven animations. This PR is a step forward towards feature parity between JS and native implementations of Animated.
Here is a link to example video that shows how tracking can be used to implement chat heads effect: https://twitter.com/kzzzf/status/958362032650244101
In addition this PR fixes an issue with frames animation driver on Android that because of rounding issues was taking one extra frame to start. Because of that change I had to update a number of Android unit tests that were relying on that behavior and running that one additional animation step prior to performing checks.
As a part of this PR I'm adding three unit tests for each of the platforms that verifies most important aspects of this implementation. Please refer to the code and look at the test cases top level comments to learn what they do.
I'm also adding a section to "Native Animated Example" screen in RNTester app that provides a test case for tracking. In the example we have blue square that fallows the red line drawn on screen. Line uses Animated.Value for it's position while square is connected via tracking spring animation to that value. So it is ought to follow the line. When user taps in the area surrounding the button new position for the red line is selected at random and the value updates. Then we can watch blue screen animate to that position.
You can also refer to this video that I use to demonstrate how tracking can be linked with native gesture events using react-native-gesture-handler lib: https://twitter.com/kzzzf/status/958362032650244101

There are some errors I noticed after upgrading my flow version. I had them in my project, and they were also reported in #11655. These errors were ignored on master, but I went through and fixed them so the static analysis will work still.
After these changes, I receive no errors using flow `0.60.1` on latest master, or using `0.59` in my local project (which does not have the requisite ignores included).
- init a new project
`react-native init --version <path-to-repo> helloworld`
- add the flow binary
`yarn add -D flow-bin`
- run flow
`yarn flow`
- make sure there are no errors in the project.
```
No errors!
✨ Done in 23.60s.

I want to animate `shadowOpacity` style property with Native Animated (`useNativeDriver: true`). This is useful for example in an ios-like navigation transition where the shadow fades in with the view that is sliding in from the side. Code comment for `STYLES_WHITELIST` says:
_In general native animated implementation should support any numeric property that doesn't need to be updated through the shadow view hierarchy (all non-layout properties)._
so I just added `shadowOpacity` (and `shadowRadius` too because why not?).
Before this change, setting `shadowOpacity` (or `shadowRadius`) to an `AnimatedValue` (with `useNativeDriver: true`) would throw the error: `Style property 'shadowOpacity' is not supported by the native animated module`.
After adding `shadowOpacity` (and `shadowRadius`), there is no error. The animation looks correct so it seems to be working. I also tried setting a ridiculously large `shadowRadius` and could see that working too.
Please advice on any further testing I should do.

Summary:
As I was working on mimicking iOS animations for my ongoing work with `react-navigation`, one task I had was to match the "push from right" animation that is common in UINavigationController.
I was able to grab the exact animation values for this animation with some LLDB magic, and found that the screen is animated using a `CASpringAnimation` with the parameters:
- stiffness: 1000
- damping: 500
- mass: 3
After spending a considerable amount of time attempting to replicate the spring created with these values by CASpringAnimation by specifying values for tension and friction in the current `Animated.spring` implementation, I was unable to come up with mathematically equivalent values that could replicate the spring _exactly_.
After doing some research, I ended up disassembling the QuartzCore framework, reading the assembly, and determined that Apple's implementation of `CASpringAnimation` does not use an integrated, numerical animation model as we do in Animated.spring, but instead solved for the closed form of the equations that govern damped harmonic oscillation (the differential equations themselves are [here](https://en.wikipedia.org/wiki/Harmonic_oscillator#Damped_harmonic_oscillator), and a paper describing the math to arrive at the closed-form solution to the second-order ODE that describes the DHO is [here](http://planetmath.org/sites/default/files/texpdf/39745.pdf)).
Though we can get the currently implemented RK4 integration close by tweaking some values, it is, the current model is at it's core, an approximation. It seemed that if I wanted to implement the `CASpringAnimation` behavior _exactly_, I needed to implement the analytical model (as is implemented in `CASpringAnimation`) in `Animated`.
We add three new optional parameters to `Animated.spring` (to both the JS and native implementations):
- `stiffness`, a value describing the spring's stiffness coefficient
- `damping`, a value defining how the spring's motion should be damped due to the forces of friction (technically called the _viscous damping coefficient_).
- `mass`, a value describing the mass of the object attached to the end of the simulated spring
Just like if a developer were to specify `bounciness`/`speed` and `tension`/`friction` in the same config, specifying any of these new parameters while also specifying the aforementioned config values will cause an error to be thrown.
~Defaults for `Animated.spring` across all three implementations (JS/iOS/Android) stay the same, so this is intended to be *a non-breaking change*.~
~If `stiffness`, `damping`, or `mass` are provided in the config, we switch to animating the spring with the new damped harmonic oscillator model (`DHO` as described in the code).~
We replace the old RK4 integration implementation with our new analytic implementation. Tension/friction nicely correspond directly to stiffness/damping with the mass of the spring locked at 1. This is intended to be *a non-breaking change*, but there may be very slight differences in people's springs (maybe not even noticeable to the naked eye), given the fact that this implementation is more accurate.
The DHO animation algorithm will calculate the _position_ of the spring at time _t_ explicitly and in an analytical fashion, and use this calculation to update the animation's value. It will also analytically calculate the velocity at time _t_, so as to allow animated value tracking to continue to work as expected.
Also, docs have been updated to cover the new configuration options (and also I added docs for Animated configuration options that were missing, such as `restDisplacementThreshold`, etc).
Run tests. Run "Animated Gratuitous App" and "NativeAnimation" example in RNTester.

Summary:
AnimatedImplementation.js is getting pretty hard to navigate and reason about so I split it up into different modules. Also took the opportunity to run prettier on that code and do some minor const/let refactorings. This doesn't change any logic, mostly just moves code around and add proper imports / exports.
This opens the door for further cleanup and flow type improvements but want to keep this already big PR as small as possible.
Discussion points:
- Should I use haste for this? Animated is pretty much a standalone module, it still uses a few haste imports but for new modules I used commonjs imports to avoid polluting the haste global namespace too much. The new modules are all internal to Animated and should not be imported externally.
- We're using `requestAnimationFrame` from fbjs instead of the one available globally in RN and browsers is there a reason for that?
- Should we even support web in this implementation? There is a standalone repo that exist for Animated web. Is this implementation of Animated web used internally at facebook?
- Probably still related to web, we used some weird Set polyfill is that still needed?
Notes:
There is a small regression for docs where the type of some classes that are exported like AnimatedValue show up as CallExpression instead if Class.

Summary:
At present, there's no uniform way of determining whether you've received an Animated value node which can be attached to an animated prop.
You can attempt to use `instanceof Animated.Value`, but this fails for interpolated values. You can use `instanceof Animated.Interpolation`, but this fails for the values that are returned from the math functions (e.g., `Animated.Add`).
This commit exposes the base type from which all of these value nodes derive. As such, it is now possible to do the following:
```js
import React, { Component, PropTypes } from 'react';
import { Animated } from 'react-native';
class Widget extends Component {
static propTypes = {
progress: PropTypes.instanceOf(Animated.Node).isRequired,
}
// ...
}
```
Unnecessary for cosmetic change.

Summary:
Fixes the error `Trying to update interpolation node that has not been
attached to the parent` in android which occurs when using multiple
Animated.Values along with interpolation and an animation is run before
another one that uses interpolation. On ios, no error is thrown in such
case but the animation also doesn't work as expected.
You can check the snack code here which works properly without
useNativeDriver: true. But fails on android and skips the first stage
of animation on ios.

**Test Plan**
The animations worked properly after the __makeNative override made
the parent node native as well.

Summary:
When using native animated we don't go through the shadow thread and use the NativeViewHierachyOptimizer so we have to make sure the views won't get optimized away. Also since we are not passing certain props because they are driven by native it is possible that the view will be marked as layout only when in fact it is not.
**Test plan**
Animated a simple view that will be collapsed with native animated and reproduce the error (it's actually just an error log in logcat now and no longer a redscreen) and checked that this fixes it.

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.
