Reviewed by Kent Tamura.

Source/WebCore:

Accept ArrayBufferView as an argument of WebSocket.send() to comply with recent change
in specification: <http://html5.org/tools/web-apps-tracker?from=7084&to=7085>.

Once WebSocket.send(ArrayBuffer) was removed from the specification, but added back
in <http://html5.org/tools/web-apps-tracker?from=7202&to=7203>. Thus the functionality
of send(ArrayBuffer) is kept as-is.

Tests: http/tests/websocket/tests/hybi/send-arraybufferview.html
       http/tests/websocket/tests/hybi/workers/send-arraybufferview.html

* Modules/websockets/ThreadableWebSocketChannel.h:
Change the signature of send() to receive offset and length so the clients can send
subrange of an ArrayBuffer.
* Modules/websockets/WebSocket.cpp:
(WebCore::WebSocket::send):
WebSocket.send(ArrayBufferView) is added, which puts the sub region of the given
ArrayBuffer into the outgoing frame queue.
* Modules/websockets/WebSocket.h:
* Modules/websockets/WebSocket.idl:
* Modules/websockets/WebSocketChannel.cpp:
(WebCore::WebSocketChannel::send):

* Modules/websockets/WorkerThreadableWebSocketChannel.cpp:

* Modules/websockets/WorkerThreadableWebSocketChannel.h:
(WorkerThreadableWebSocketChannel):
(Bridge):
* bindings/js/JSWebSocketCustom.cpp:

Source/WebKit/chromium:

* src/WebSocketImpl.cpp:
(WebKit::WebSocketImpl::sendArrayBuffer):
Apply change in function signature of WebSocketChannel::send().

LayoutTests:

Two tests are added to check whether WebSocket.send(ArrayBufferView) works in the
main thread and in a worker.
