Rough start for simple, tunneling websocket proxy support.
Compiles at this stage and that's all I know :)

force correct scheme info

We need to ensure a conn_rec

Work around blocking issues...

And now pass the initial request to the backend...

I dislike this duplication of code from mod_proxy_http()
but maybe it's inevitable. I may create ap_proxy_create_headerb()
to create a header brigade that both modules can use.

Pull out duplicated code to proxy_util...

rename extension module... tunnel is more accurate

log nums

"final" rename :)

don't strip these, ensure that they exist.

streamline

bypass reqtimeout for websockets

Keep mod_req clear. Simply scan thru input filters and
remove it within the ws submodule. Nasty, but it keeps
mod_req untouched (for now ;) )
