[Qemu-devel] [PATCH] vnc: added initial websockets support

[Tim Hardeck]

This patch adds basic Websockets support to the QEMU VNC component. Websockets 
allow every modern web browser to connect to QEMU VNC without any additional 
plugins.

Because of the GnuTLS requirement the Websockets implementation is optional 
(--enable-vnc-ws).

Websockets connections are recognized by waiting 500ms for a Websocket 
handshake. If no data is received a regular vnc connection is assumed.
If this is not acceptable please suggest if Websockets should be activated by a 
new VNC option or by an additional console parameter on a different port.

SHA1 is required for the handshake which is generated with GnuTLS. Since using 
GnuTLS does automatically activate VNC-TLS, which has warnings about deprecated 
parts, I have changed the configure script to disable VNC-TLS if not explicitly 
enabled.

The Websockets support was tested with noVNC http://kanaka.github.com/noVNC/ .

I have used parts of the LibVNC websockets implementation that's why I have 
added the GPL header to the new files. I hope that it is fine that way.
