Summary: RCTShadowText currently overrides a couple methods from RCTShadowView to reset the count of the cssNode children to 0. This diff instead moves that logic into RCTShadowView behind a configurable flag making it easier to reason about.

Summary: fillCSSNode was only ever used in RCTShadowView to set the child count which is already performed in insert/remove subview calls and in RCTShadowText is was used to set the measure function which can be done in the initializer instead.

Summary:
iOS follow up to #8569. This currently depends on the Android PR since it contains the JS implementation, only review the last commit. Just putting this out here for visibility, don't merge this before the Android PR.
**Test plan**
Tested by running a background task that burns all remaining idle time (see UIExplorer example).
Tested that native only calls into JS when there are pending idle callbacks.
Tested that timers are executed before idle callback.

Summary:
- Avoid using `+initialize`, use dispatch_once instead; it should be equivalent but more performant.
- Don't even let the `isPackagerRunning:` and `guessPackagerHost` methods exist unless `RCT_DEV` is on; they didn't do anything interesting when it is off.

Summary:
Attempt to fix#7919.
Currently, if the app is launched into the background and you read `AppState.currentState` too soon, you will see the value `'active'` instead of `'background'`. This is because the default value of `AppState.currentState` is hardcoded to be `'active'` and it is initialized with the actual value asynchronously.
This attempts to fix the bug by having the `RCTAppState` module provide the initial state as a module constant.
As noted in #7919, it looks like this fix was already tried and reverted with 0fb3d8de83. zjj010104, hedgerwang, nicklockwood -- can you explain why? I would very much like to get this bug fixed. Nobody has followed up on the issue I filed so I decided to just go ahead and make a PR with my best guess at a fix.

Summary:
This diff exposes a new experimental method `[RCTJavaScriptLoader +attemptSynchronousLoadOfBundleAtURL:sourceLength:error:]`. It may be used if you know that a specific call site must load its JavaScript synchronously, or else fail entirely.
This new API will succeed for file URLs that point to a RAM bundle. It will fail for non-RAM-bundle files and for HTTP URLs.
This also cleans up the error domain and codes for this class. This should be the only externally visible change from this diff if you don't use the new API: the codes and domains you receive from the API may change slightly. They were pretty sloppy and undocumented before, so I think this change is for the better.

Summary:
The `initWithJSContextProvider:` API created a `RCTJSCExecutor` with a thread/context that already exists, but it did not solve the problem of loading an actual application script; the `executeApplicationScript:` API is also asynchronous.
Create a new merged API that allows you to pass in a pre-created thread/context pair and immediately receive an `RCTJSCExector` that has already executed a specified application script.
This also removes the `underlyingJSContext` API entirely, in favor of passing it back in a byref variable in the new API. This minimizes the surface area for API abuse.

Summary:
Instead of two separate dispatches to the JavaScript thread, only do one. Avoid the strongSelf dance entirely.
This refactor does mean that the cost of registering the nativeRequire hook on the context is not measured by the `RCTPLRAMBundleLoad` tag. However it should be almost zero-cost to construct and set a single block, so I'm OK with that change.

Summary:
By default we run the the JS display link, even if there are no modules listening. Given that most listeners will be lazily constructed, let's make it paused by default.
Since RCTTiming almost never unpauses due to some long-lived timers, implement a sleep timer that pauses the displaylink but uses an NSTimer to wake up in time.

Summary:
Currently React Native codebase treats JS stack traces as array of dictionaries.
This diff switches the Red Box to use new `RCTJSStackFrame` for internal data representation, while keeping the exposed API unchanged. The next step would be to replace the rest of manual parsing and usage of dictionaries.
The new class has ability to parse the stack from raw strings or dictionaries.
