Summary:
This simplifies the first log message for every single reload. Here are the changes:
* I dropped the "application" word because at Facebook we consider these views "surfaces". However, the method is explicitly called "runApplication" because in open source most people will only have a single "application". Removing the word and instead relying on the user specified string avoids the naming problem and doesn't take away from the information.
* I removed the `__DEV__` and performance optimization log. The way RN is set up, developers will always have the correct settings for these in either dev or prod and printing them every time is superfluous. Also, it had a typo. How is it possible nobody ever noticed this?
* I also simplified the invariant below to be half as long. I think it still has the same amount of information with fewer words (this is shown in a RedBox where there isn't that much space)

Summary:
`setTimeout` inside a headless JS task does not always works; the function does not get invoked until the user starts an `Activity`.
This was attempted to be used in the context of widgets. When the widget update or user interaction causes the process and React context to be created, the headless JS task may run before other app-specific JS initialisation logic has completed. If it's not possible to change the behaviour of the pre-requisites to be synchronous, then the headless JS task blocks such asynchronous JS work that it may depend on. A primitive solution is the use of `setTimeout` in order to wait for the pre-conditions to be met before continuing with the rest of the headless JS task. But as the function passed to `setTimeout` is not always called, the task will not run to completion.
This PR solves this scenario by allowing the task to be retried again with a delay. If the task returns a promise that resolves to a `{'timeout': number}` object, `AppRegistry.js` will not notify that the task has finished as per master, instead it will tell `HeadlessJsContext` to `startTask` again (cleaning up any posted `Runnable`s beforehand) via a `Handler` within the `HeadlessJsContext`.
Documentation also updated here: https://github.com/facebook/react-native-website/pull/771
### AppRegistry.js
If the task provider does not return any data, or if the data it returns does not contain `timeout` as a number, then it behaves as `master`; notifies that the task has finished. If the response does contain `{timeout: number}`, then it will attempt to queue a retry. If that fails, then it will behaves as if the task provider returned no response i.e. behaves as `master` again. If the retry was successfully queued, then there is nothing to do as we do not want the `Service` to stop itself.
### HeadlessJsTaskSupportModule.java
Similar to notify start/finished, we simply check if the context is running, and if so, pass the request onto `HeadlessJsTaskContext`. The only difference here is that we return a `Promise`, so that `AppRegistry`, as above, knows whether the enqueuing failed and thus needs to perform the usual task clean-up.
### HeadlessJsTaskContext.java
Before retrying, we need to clean-up any timeout `Runnable`'s posted for the first attempt. Then we need to copy the task config so that if this retry (second attempt) also fails, then on the third attempt (second retry) we do not run into a consumed exception. This is also why in `startTask` we copy the config before putting it in the `Map`, so that the initial attempt does leave the config's in the map as consumed. Then we post a `Runnable` to call `startTask` on the main thread's `Handler`. We use the same `taskId` because the `Service` is keeping track of active task IDs in order to calculate whether it needs to `stopSelf`. This negates the need to inform the `Service` of a new task id and us having to remove the old one.
## Changelog
[Android][added] - Allow headless JS tasks to return a promise that will cause the task to be retried again with the specified delay

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:
Start a `HeadlessJsTaskService` on Android without registered is dangerous on apps because `HeadlessJsTaskService` will acquire a [`PARTIAL_WAKE_LOCK`](https://developer.android.com/topic/performance/vitals/wakelock), without calling `onHeadlessJsTaskFinish` this lock won't release until timeout(if exist). This lock will prevent the android device from sleeping.
Although on JS will throw an error if no headless tasks registered, but it's hard to notice while app in the background. No visual information is displayed.
This PR will log a warning instead of Error, and just mark the task to finished on native if nothing registered in order to release the wake lock.

Summary:
On UWP, when the app is executing a Background task, the OS can request it to cancel the task (for various reasons). If the app does not cancel its background task quickly, the OS might terminate the app.
This change adds support to cancel the headless task which can be used by native code to forward the cancellation request from the OS to the JS code.

Summary:
This PR removes the need for having the `providesModule` tags in all the modules in the repository.
It configures Flow, Jest and Metro to get the module names from the filenames (`Libraries/Animated/src/nodes/AnimatedInterpolation.js` => `AnimatedInterpolation`)
* Checked the Flow configuration by running flow on the project root (no errors):
```
yarn flow
```
* Checked the Jest configuration by running the tests with a clean cache:
```
yarn jest --clearCache && yarn test
```
* Checked the Metro configuration by starting the server with a clean cache and requesting some bundles:
```
yarn run start --reset-cache
curl 'localhost:8081/IntegrationTests/AccessibilityManagerTest.bundle?platform=android'
curl 'localhost:8081/Libraries/Alert/Alert.bundle?platform=ios'

Summary:
If tracking is enabled and the sampling check passes on a scroll or layout event,
we compare the scroll offset to the layout of the rendered items. If the items don't cover
the visible area of the list, we fire an `onFillRateExceeded` call with relevant stats for
logging the event through an analytics pipeline.
The measurement methodology is a little jank because everything is async, but it seems directionally
useful for getting ballpark numbers, catching regressions, and tracking improvements.
Benchmark testing shows a ~2014 MotoX starts hitting the fill rate limit at about 2500 px / sec,
which is pretty fast scrolling.
This also reworks our frame rate stuff so we can use a shared `SceneTracking` thing and track blankness
globally.

Summary:
This adds a flowified JS module for the FrameRateLogger native module and plugs
it into `ScrollResponder` and `AppRegistry`.
If there is no `FrameRateLogger` native module, then the function calls will be no-ops.
One major limitation is that we can't track animated/programatic scrolls because we don't
have reliable end events. Would be generally useful to add those in a followup though.
