Summary:
public
This diff replaces the RegEx module method parser with a handwritten recursive descent parser that's faster and easier to maintain.
The new parser is ~8 times faster when tested on the UIManager.managerChildren() method, and uses ~1/10 as much RAM.
The new parser also supports lightweight generics, and is more tolerant of white space.
(This means that you now can – and should – use types like `NSArray<NSString *> *` for your exported properties and method arguments, instead of `NSStringArray`).

Summary: public
The `bridge.modules` dictionary provides access to all native modules, but this API requires that every module is initialized in advance so that any module can be accessed.
This diff introduces a better API that will allow modules to be initialized lazily as they are needed, and deprecates `bridge.modules` (modules that use it will still work, but should be rewritten to use `bridge.moduleClasses` or `-[bridge moduleForName/Class:` instead.
The rules are now as follows:
* Any module that overrides `init` or `setBridge:` will be initialized on the main thread when the bridge is created
* Any module that implements `constantsToExport:` will be initialized later when the config is exported (the module itself will be initialized on a background queue, but `constantsToExport:` will still be called on the main thread.
* All other modules will be initialized lazily when a method is first called on them.
These rules may seem slightly arcane, but they have the advantage of not violating any assumptions that may have been made by existing code - any module written under the original assumption that it would be initialized synchronously on the main thread when the bridge is created should still function exactly the same, but modules that avoid overriding `init` or `setBridge:` will now be loaded lazily.
I've rewritten most of the standard modules to take advantage of this new lazy loading, with the following results:
Out of the 65 modules included in UIExplorer:
* 16 are initialized on the main thread when the bridge is created
* A further 8 are initialized when the config is exported to JS
* The remaining 41 will be initialized lazily on-demand

Summary: public
Add RCTFatal for reporting fatal runtime conditions. This centralizes failure handling to one function and allows you to customize how they should be handled. RCTFatal will be logged to the console and as a redbox and will also be triggered by fatal exceptions coming from RCTExceptionsManager.
Note that there is no RCTLogFatal, since just logging the fatal condition does not allow us to handle it consistently.

Summary: public
Added lightweight genarics annotations to make the code more readable and help the compiler catch bugs.
Fixed some type bugs and improved bridge validation in a few places.

Summary: - Includes the error cookie with soft exceptions as well since they too can be updated (requires tiny Android change too)
- Passes the error cookie through instead of leaving it unused

This probably needs more thought - might want to differentiate between console.error and reportError.
Test Plan: console.error and reportError no longer redbox. invariant and RCTLogError still do.
Summary:
@public
There have been multiple instances of confusion about whether a redbox means the
developer did something they shouldn't but things will keep working, or if
something went horribly wrong and the app will crash in prod. This diff
introduces an orange background color to the redbox for `console.error` and
`RCTLogError` to indicate that something bad happened, but that the app will
continue working.
Test Plan:

Summary:
@public
ErrorUtils.reportError is intended for reporting handled errors to the
server, like timeouts, which means that we shouldn't shove them in the
developer's face.
Test Plan: add `require('ErrorUtils').reportError(new Error('error'))` and see a useful error message with stack but no redbox. Debugger confirms `reportSoftException` is called but it doesn't do anything yet. `reportFatalError` and throwing exceptions still show redboxes.
