Similar to #426, but this will allow us to only intercept xpra packets, regular packets can be forwarded to a web server which can respond to regular HTTP packets.

[[BR]]

immediate benefits:

• a scan will show the port as belonging to the web server and xpra remains hidden
• we can server an html5 client page (html5 client #473) through the same server port

PoC patch which does the multiplexing for http get requests only in "ServerBase"

r4948 implements this and will allow us to do #473 much more easily.

Here's how to test:

• start a web server on port 8000:

thttpd -p 8000

• verify you can browse to it:

xdg-open http://SERVERIP:8000/

• start an xpra server with the tcp proxy option pointing to this web server we have just started:

xpra start :10 --bind-tcp=10000 --start-child=xterm --tcp-proxy=127.0.0.1:8000

• verify you can attach to this server:

xpra attach tcp:SERVERIP:10000

• verify you can hit the web server on this same port, ie: open your browser at:

http://SERVERIP:10000/
