Summary:
@public
Add PerformanceLogger to keep track of JS download, initial script execution and
full TTI.
Test Plan:
The Native side currently calls `addTimespans` when it's finish initializing
with the six values (start and end for the three events), so I just checked it
with a `PerformanceLogger.logTimespans()` at the end of the function.

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:
@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.
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.
Summary:
@public
Remove extra `JSGlobalContextRetain` that was causing the context ref to leak +
remove `self` reference from block and improve invalidation
Test Plan:
Run the UIExplorer, reload the app a few times, verify that the memory usage is
not increasing.
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.
Summary:
@public
Right now the profiler shows how long the executor took on JS but doesn't show
how long each of the batched calls took, this adds a *very* high level view of JS
execution (still doesn't show properly calls dispatched with setImmediate)
Also added a global property on JS to avoid trips to Native when profiling is
disabled.
Test Plan:
Run the Profiler on any app
{F22491690}
Summary:
This converts the existing JSEvaluateScript call for `require('<ModuleName>').<MethodName>.apply(null, <args>);` to native JSC C API methods which shaves off about 10-15% of invocation time on average, I used pretty primitive profiling methods to track the minimum, maximum and average invocation time so would appreciate any extra eyes on the performance.
If the argument count is zero the method is invoked directly with no arguments, if the argument count is 1 it's invoked directly with just that argument. If there is more than 1 argument then apply is used and the arguments are passed as the second parameter.
Ensured all existing tests pass and instruments leaks shows nothing is leaking.
