Source/WebCore:

Second attempt to remove leaks around WorkerThreadableWebSocketChannel.

No new tests, as this patch does not impose any functional change.

* Modules/websockets/ThreadableWebSocketChannelClientWrapper.cpp:
(WebCore::ThreadableWebSocketChannelClientWrapper::ThreadableWebSocketChannelClientWrapper):
(WebCore::ThreadableWebSocketChannelClientWrapper::failedWebSocketChannelCreation):
(WebCore::ThreadableWebSocketChannelClientWrapper::setFailedWebSocketChannelCreation):
* Modules/websockets/ThreadableWebSocketChannelClientWrapper.h:
Add a boolean flag indicating whether Bridge::initialize() has exited without receiving
a pointer to the peer object.
* Modules/websockets/WorkerThreadableWebSocketChannel.cpp:
(WebCore::WorkerThreadableWebSocketChannel::WorkerContextDidInitializeTask::create):
(WebCore::WorkerThreadableWebSocketChannel::WorkerContextDidInitializeTask::WorkerContextDidInitializeTask):
(WebCore::WorkerThreadableWebSocketChannel::WorkerContextDidInitializeTask::performTask):
Kick mainThreadDestroy() to delete the peer if the bridge has failed to receive
a pointer to the peer (waitForMethodCompletion() exited due to message queue's
termination).
(WebCore::WorkerThreadableWebSocketChannel::Bridge::mainThreadInitialize):
(WebCore::WorkerThreadableWebSocketChannel::Bridge::initialize):
* Modules/websockets/WorkerThreadableWebSocketChannel.h:
(WorkerThreadableWebSocketChannel):
Make WorkerContextDidInitializeTask an inner class of WorkerThreadableWebSocketChannel
so it can refer WorkerThreadableWebSocketChannel's static member function (mainThreadDestroy()).

Source/WebKit/chromium:

* src/WebWorkerClientImpl.cpp:
(WebKit::WebWorkerClientImpl::postTaskForModeToWorkerContext):
Correctly propagate the return value of postTaskForModeToWorkerContext().
