Summary:Add a couple functions to show and hide a small window with buttons to start/stop
systrace and reload the current bridge. After stop profiling, the results will
be saved to a temporary file, and a share sheet will show up with the file attached
so that you can send it to your computer whatever way is more convenient.

NSJSONSerialization throws an exception when it encounters bad JSON data, including NaN values, which may not be a programming error.
This diff adds code to catch those exceptions and convert to an error. Also, if no error handling is in place, RCTJSONStringify will now display a redbox, and attempt to recover by sanitizing the JSON data and retrying.

Summary:

Thanks to the new lazy initialization system for modules, `RCTDidCreateNativeModules` no longer does what the name implies.
Previously, `RCTDidCreateNativeModules` was fired after all native modules had been initialized. Now, it simply fires each time the bridge is reloaded. Modules are created on demand when they are needed, so most of the assumptions about when `RCTDidCreateNativeModules` will fire are now incorrect.
This diff deprecates `RCTDidCreateNativeModules`, and adds a new notification, `RCTDidInitializeModuleNotification`, which fires each time a module a new module is instantiated.
If you need to access a module at any time you can just call `-[bridge moduleForClass:]` and the module will be instantiated on demand. If you want to access a module *only* after it has already been instantiated, you can use the `RCTDidInitializeModuleNotification` notification.

Summary:

A lot of the core modules have to use private methods in the bridge, specially
since the `RCTBatchedBridge` interface is never exposed. That was leading to a
lot of different private bridge categories spread across different modules,
which makes harder to identify which modules are affected by private API changes.
Replace all the categories with a single private header.

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

Replace it with an ugly `#if` that checks if it's any of the supported targets
