vnc: added initial websocket protocol support

Browse source 
This patch adds basic Websocket Protocol version 13 - RFC 6455 - support
to QEMU VNC. Binary encoding support on the client side is mandatory.

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

To activate Websocket support the VNC option "websocket"is used, for
example "-vnc :0,websocket".
The listen port for Websocket connections is (5700 + display) so if
QEMU VNC is started with :0 the Websocket port would be 5700.
As an alternative the Websocket port could be manually specified by
using ",websocket=<port>" instead.

Parts of the implementation base on Anthony Liguori's QEMU Websocket
patch from 2010 and on Joel Martin's LibVNC Websocket implementation.

connections (@var{host}:@var{d},@code{reverse}), the @var{d} argument
is a TCP port number, not a display number.
@item websocket
Opens an additional TCP listening port dedicated to VNC Websocket connections.
By defintion the Websocket port is 5700+@var{display}. If @var{host} is
specified connections will only be allowed from this host.
As an alternative the Websocket port could be specified by using
@code{websocket}=@var{port}.
@item password
Require that password based authentication is used for client connections.
