Frédéric Sagnes 4a3857ef1d Use JSStringCreateWithUTF8CString and skip NSString decoding when loading the bundle
Summary: public

Benchmarking our startup path has shown we spend a lot of time decoding strings (iPhone 4S / iPhone 5):

* reading a 2MB JS bundle: 35ms / 15ms
* decoding is to an `NSString`: 186ms / 78ms
* transforming that to a `JSString`: 29ms / 10ms

Instead of going through an `NSString` transformation, we generate a null-terminated bundle (0.1ms / 0.05ms to copy the data) and use `JSStringCreateWithUTF8CString` (121ms / 53ms) to generate the string. That makes decoding 70% faster.

Harrison Harnisch 46c6cde947 UI CPU and memory utilization graphs in Chrome debugging mode
Summary:
Chrome debugging UI is currently only showing connection state and logs in the console, leaving room for plenty of interesting information.

I've pushed the UI (using the same convention set by FPS -- UI/JS) CPU and memory utilization data over the debug Websocket and tapped into the existing stream of JS calls that get ran in V8.

The number of JS calls in a time interval is counted for all sub calls in a batch
https://github.com/hharnisc/react-native/blob/master/packager/debugger.html#L150

The last 5 batches of JS calls are displayed in a list format.

Summary:
RCTConvert's URL: method gracefully handles unescaped urls, local file urls, urls containing unicode, etc. URLWithString doesn't.

Tadeu Zagallo 127f7095dc [ReactNative] Add RCTBridgeDelegate

Add a new bridge delegate protocol to allow a more flexible bridge configuration.

For now it just support the pre-existent configurations + providing the JavaScript
source to the bridge, that should allow pre-loading sources.

Nick Lockwood 650fc9de4c Increased warning levels to -Wall -Wextra, and fixed Xcode 7 beta issues
Summary:
@public

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 efd386eba2 [ReactNative] Fix timers for debugger executors
Summary:
@public

`-[RCTJavaScriptExecutor executeBlockOnJavaScriptQueue:]` would always `dispatch_async`
for the WebView and WebSocket executors, what caused for any frame aligned dispatch.

Test Plan:
Test the `Timers, TimerMixin` example on UIExplorer, `requestAnimationFrame` was
taking ~33.3ms when debugging, now takes ~16.6ms as expected.

Tadeu Zagallo 847dff8d75 [ReactNative] Make JavaScript executors bridge modules
Summary:
@public

This is the first of a few diffs that change the way the executors are handled
by the bridge.

For they are just promoted to modules, so they are automatically loaded by the bridge.

Test Plan:
Tested on UIExplorer, Catalyst and MAdMan.
Tested all the 3 executors, everything looks fine.
