Summary:
Modules which call JS methods directly, or use `sendDeviceEventWithName:`, can trigger effects in JS without ever being referenced from the JS code. This breaks some assumptions in my earlier diff about when modules can be lazily loaded.
Pending a better solution, I've put explicit `init` methods in these modules to ensure they are eagerly initialized (the downside to this is that they'll still be initialized even if they are never used).

Summary:
Previously, if a module implemented `setBridge:` we assumed that it needs to be initialised on the main thread. This assumption was not really warranted however, and it was a barrier to deferring module initialization.
This diff tweaks the rules so that only modules that override `init` or `constantsToExport**` are assumed to require main thread initialization, and others can be created lazily when they are first used.
WARNING: this will be a breaking change to any 3rd party modules that are assuming `setBridge:` is called on the main thread. Those modules should be rewritten to move any code that requires the main thread into `init` or `constantsToExport` instead.
`**` We will also be examining whether `constantsToExport` can be done lazily, but for now any module that uses it will still be created eagerly when the bridge starts up.

Then more people add logs and not only do the logs are not useful, they prevent people from actually using them when debugging.

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:
public
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

blocking the caller thread for longer than it should. Replace it with a private

Use macros to also defer work done when generate the name of the events.
