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 ;) )

Reduce stack usage, 32 bytes are enough here, no need to take 8k in the stack. (19 would be enough, but be safe...)

Use the size of the buffer as opposed to MAX_STRING_LEN.
