Nick Lockwood 060664fd3d Refactored module access to allow for lazy loading
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

Nick Lockwood c5b990f65f Added lightweight generic annotations
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.

Dave Sibiski 6c7c845145 Implements `onKeyPress`
Summary: - When a key is pressed, it's `key value` is passed as an argument to the callback handler.
 - For `Enter` and `Backspace` keys, I'm using their `key value` as defined [here](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/key#Key_values). As per JonasJonny & brentvatne's [suggestion](https://github.com/facebook/react-native/issues/1882#issuecomment-123485883).

- Example
```javascript
 _handleKeyPress: function(e) {
      console.log(e.nativeEvent.key);
  },

  render: function() {
    return (
      <View style={styles.container}>
        <TextInput
            style={{width: 150, height: 25, borderWidth: 0.5}}
            onKeyPress={this._handleKeyPress}
        />
        <TextInput
            style={{width: 150, height: 100, borderWidth: 0.5}}
            onKeyPress={this._handleKeyPress}
            multiline={true}
        />
      </View>
    );
  }
```

Nick Lockwood 48af214216 Simplified event registration
Summary:
Our events all follow a common pattern, so there's no good reason why the configuration should be so verbose. This diff eliminates that redundancy, and gives us the freedom to simplify the underlying mechanism in future without further churning the call sites.

Spencer Ahrens 961c1eb429 [ReactNative] TextInput bug fixes and features
Summary:
This introduces event counts to make sure JS doesn't set out of date values on
native text inputs, which can cause dropped characters and can mess with
autocomplete, and obviates the need for the input buffering which added lag and
complexity to the component.  Made sure to test simulated super-slow JS text
event processing to make sure characters aren't dropped, as well as typing
obviously correctable words and making sure autocomplete works as expected.

TextInput is now a controlled input by default without causing any issues for
most cases, so I removed the `controlled` prop.

Fixes selection state jumping by restoring it after setting new text values, so
highlighting the middle of some text in the new ReWrite example and hitting
space will replace that selection with an underscore and keep the cursor at a
sensible position as expected, instead of jumping to the end.

Ads `maxLength` prop to support the most commonly needed syncronous behavior:
preventing the user from typing too many characters.  It can also be used to
prevent users from continuing to type after entering special characters by
changing it to the current length after a regex match.  Made sure to verify it
works well with pasted input (including in the middle of existing text),
truncating it and collapsing the selection the same way it does on the web.

Fixes bug in TextEventsExample where it wouldn't show the submit and end events,
even though there were firing correctly.

Tadeu Zagallo d3065fc2e7 [ReactNative] Remove RCT_IMPORT_METHOD macro and generate lookup table dynamically
Summary:
@public

This removes the last piece of data that was still stored on the DATA section,
`RCT_IMPORT_METHOD`. JS calls now dynamically populate a lookup table simultaneously
on JS and Native, instead of creating  a mapping at load time.

Test Plan: Everything still runs, tests are green.

Summary:

I've increased the warning levels in the OSS frameworks, which caught a bunch of minor issues. I also fixed some new errors in Xcode 7 relating to designated initializers and TLS security.

Test Plan:
* Test the sample apps and make sure they still work.
* Run tests.

Tadeu Zagallo c2fb21b322 [ReactNative] Properly pause frame update observers when idle
Summary:
@public

`RCTDispatchEvent` and `RCTTiming` weren't being paused when there wasn't any
work left to be done.

Test Plan:
Run the timers example - check everything still works as expected
Test the ListView paging example - check scroll events are still fired as expected
Launch UIExplorer, let it idle, and put a break point on `-[RCTBridge dispatchBlock:moduleID:]`,
it should never fire.

Tadeu Zagallo 777363fdd7 [ReactNative] Use NSDictionary + NSNumber for event coalescing
Summary:
@public

On D2099270 event coalescing was implemented and the event key on the RCTSparseArray
is an uint64_t, but it was declared as NSUInteger.  On a 32 bits architecture
it'll be clipped to 4 bits, meaning that just `reactTag` will be taken into
account, e.g. different types of events can coalesce with each other if they target the same view

Switching to use an NSMutableDictionary instead of RCTSparseArray and NSNumber
as keys instead of uint64_t

Test Plan: Fixed the previous tests and added a new test to RCTEventDispatcherTests

    number of pixels scrolled = content offset + leading content inset for the scroll axis
