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

The WebView executor has no benefits compared to the JSC executor (slower, no extra debugging tools...),
and it's pretty hacky (since it injects the code in a script tag we have to check for tags in the comments and etc...).

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: public
Kill `RCTPerfStats` and introduce the new `RCTPerfMonitor`, including memory
usage, JSC heap size, number of RN views in screen, FPS (both on UI and JS threads)
and more to come.
It removes all the previous traces that were previous spread across the bridge
and the dev menu and moves everything to be more contained, so the whole thing
can be safely striped in production.

Summary: While we shouldn't invoke `bridge.devMenu` in production, doing it will result into a crash.
1. `devMenu` internally calls `RCTBridgeModuleNameForClass([RCTDevMenu class])`
2. `RCTBridgeModuleNameForClass()` calls `moduleName`
3. In the release code `RCTDevMenu` doesn't export the `moduleName` class method.

Summary: This adds workarounds for the code that was preventing React from compiling when linked against an iOS App Extension target.
Some iOS APIs are unavailable to App Extensions, and Xcode's static analysis will catch attempts to use methods that have been flagged as unavailable.
React currently uses two APIs that are off limits to extensions: `[UIApplication sharedApplication]` and `[UIAlertView initWith ...]`.
This commit adds a helper function to `RCTUtils.[hm]` called `RCTRunningInAppExtension()`, which returns `YES` if, at runtime, it can be determined that we're running in an app extension (by checking whether the path to `[NSBundle mainBundle]` has the `"appex"` path extension).
It also adds a `RCTSharedApplication()` function, which will return `nil` if running in an App Extension. If running in an App, `RCTSharedApplication()` calls `sharedApplication` by calling `performSelector:` on the `UIApplication` class. This passes the static analysis check, and, in my opinion, obeys the "spirit of th

Summary:
Add JSC profiler to the dev menu and rename the pre-existent one to systrace.
For now it just outputs to the console, but a better workflow is on the way.
