Summary:
We've seen some crashes from exceeding property limits (>200k) from storing callbacks, which is insane since callbacks should be called and cleaned up right away in most cases. Browsing around I never see more than about 50 pending callbacks when firing off a whole much of animations and measures and stuff.
In order to track down the leak, I added some code in `__DEV__` to provide more info - hopefully some developers will hit it and report the issue. Unfortunately it's not easy to get any useful information in prod because we strip all the useful debug info, but if this continues to be a problem we could try capturing that info in prod as well (and maybe other info, too).

Summary:
When a synchronous call from JS to native code throws an error, it doesn't include a useful stack trace from the native side. To improve error attribution, this diff pops the frames in `MessageQueue.js` and `NativeModules.js` from the stack traces of such errors. This uses the `error.framesToPop` convention understood by RN's global error handler.
For now we limit this to errors converted from C++ exceptions in host functions, since those are not likely to ever contain further JavaScript frames at the point where we catch them; if they did, it would violate our assumption that the top two frames of the stack are in the JS bridge code.

Summary:
Types the last 3 members of the `ModuleConfig` tuple (functions, promise method IDs, and sync method IDs) as nullable and immutable arrays. This is in line with how they are used in the code; one debug-only call site had to be fixed to account for nullability.
Also updates the test data in `MessageQueueTestConfig` to explicitly conform to this type.

Summary:
This is an ESLint plugin that infers whether an import looks like a Haste module name. To keep the linter fast and simple, it does not look in the Haste map. Instead, it looks for uppercase characters in single-name import paths, since npm has disallowed uppercase letters in package names for a long time. There are some false negatives (e.g. "merge" is a Haste module and this linter rule would not pick it up) but those are about 1.1% of the module names in the RN repo, and unit tests and integration tests will fail anyway once Haste is turned off.
You can disable the lint rule on varying granular levels with ESLint's normal disabling/enabling mechanisms.
Also rewrote more Haste imports so that the linter passes (i.e. fixed lint errors as part of this PR).

Summary:
This is the next step in moving RN towards standard path-based requires. All the requires in `Libraries` have been rewritten to use relative requires with a few exceptions, namely, `vendor` and `Renderer/oss` since those need to be changed upstream. This commit uses relative requires instead of `react-native/...` so that if Facebook were to stop syncing out certain folders and therefore remove code from the react-native package, internal code at Facebook would not need to change.
See the umbrella issue at https://github.com/facebook/react-native/issues/24316 for more detail.

Summary:
We need to move animated native module calls to synchronous so we can properly thread them in with mounting instructions in Fabric. Some of them take callbacks so we need to add support for that when switching to synchronous.
A side benefit is that we can unify codepaths a little more with async callbacks.

Summary:
Instead of assigning all the constants exported by a NativeModule to the native module JavaScript object itself, we want to instead export a `getConstants()` method that can be used to access native module constants. This change simplifies the API of native modules. Eventually, we'll remove the ability to access constants as native module object properties alltogether, but that's comes later.
**Note**: I didn't need to make any cpp changes because `JSIExecutor::NativeModuleProxy::get` calls `JSINativeModules::getModule` (here: https://goo.gl/QwPDWF), which eventually calls `JSINativeModules::createModule`, which uses `global.__fbGenNativeModule` (here: https://goo.gl/pSxMgE), which is just an alias to `genModule` in `NativeModules` (here: https://goo.gl/u2wjCs).

Summary:
`new Date().getTime()` is equal to `Date.now()`.
`Date.now()` avoids an allocation, which can save some GC time.
This micro-optimization isn't worth it in most places, but since MessageQueue is one of the hottest pieces of JS in RN, it's worth it.

Summary:
This makes JSTimers actively register a callback for callImmediates.
Besides being generally tricky, circular dependency prevent compiling React Native code with bundlers that rely on concatenating module sources rather that evaluating code at the time of requiring, like Google Closure Compiler.
Sadly, Google Closure Compiler setup that prompted this change is complicated and brittle. And there are no good public tools to find circular dependencies among Haste-style modules (with unqualified require paths).
So some advice on a good test plan would be useful. Does Facebook have any tools to find circular dependencies with Haste-style requires?
FWIW, a check that worked for me was to replace all import paths in React Native from Haste style to normal relative paths (which I needed anyway) and then run [`madge`](https://www.npmjs.com/package/madge) on the code base:
```
$ ~/node_modules/.bin/madge --circular react-native/Libraries
Processed 390 files (7.4s) (81 warnings)
✖ Found 2 circular dependencies!
1) BatchedBridge/NativeModules.js > BatchedBridge/BatchedBridge.js > BatchedBridge/MessageQueue.js > Core/Timers/JSTimers.js
2) StyleSheet/flattenStyle.js > StyleSheet/StyleSheet.js
```
(The second cycle is already eliminated in a8e3c7f578).
[GENERAL] [MINOR] [MessageQueue] - MessageQueue implementation doesn't have a circular dependency on JSTimers.

```
yarn flow
