[WebSocket] CloseEvent's code and reason properties support

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Takashi Toyoshima]

I took over this work from yutak.

Current WebSocket implementation miss CloseEvent's code and reason properties handling for updated WebSocket API.
First, I make changes to show incoming closing frame's code and reason as a CloseEvent's properties.

Current patch includes 66294, so I didn't set commit-queue flag.

Write what is changed as possible.

What does this '0'  mean?

> Source/WebCore/websockets/WebSocketChannel.cpp:101
> +    , m_closeEventCode(1005) // Indicate that no status code was actually present.

No test for 1005.
We prefer symbols to comments. We should define a const variable or an enum value for 1005, and remove the comment.

Question: Should we clear m_closeEventReason if frame.payloadLength < 3?
