MediaStream API: Schedule the RTCDataChannel events to be triggered at idle state
https://bugs.webkit.org/show_bug.cgi?id=101751

Reviewed by Adam Barth.

Source/Platform:

Making some WebRTCDataChannel methods const.

* chromium/public/WebRTCDataChannel.h:
(WebRTCDataChannel):

Source/WebCore:

This patch queues the events until the JS interpreter is in an idle state.

Existing tests cover this patch.

* Modules/mediastream/RTCDataChannel.cpp:
(WebCore::RTCDataChannel::RTCDataChannel):
(WebCore::RTCDataChannel::readyStateChanged):
(WebCore::RTCDataChannel::dataArrived):
(WebCore::RTCDataChannel::error):
(WebCore::RTCDataChannel::scheduleDispatchEvent):
(WebCore):
(WebCore::RTCDataChannel::scheduledEventTimerFired):
* Modules/mediastream/RTCDataChannel.h:
(RTCDataChannel):
* platform/chromium/support/WebRTCDataChannel.cpp:
(WebKit::WebRTCDataChannel::setBufferedAmount):
(WebKit::WebRTCDataChannel::readyStateChanged):
(WebKit::WebRTCDataChannel::dataArrived):
(WebKit::WebRTCDataChannel::error):

Tools:

Makes the data channel mocks to be synchronous instead of asynchronous to be able to
properly test RTCDataChannel event handling.

* DumpRenderTree/chromium/MockWebRTCPeerConnectionHandler.cpp:
(MockWebRTCPeerConnectionHandler::sendStringData):
(MockWebRTCPeerConnectionHandler::sendRawData):

LayoutTests:

Adding shouldNotTrow to the send() calls.
