Add ranch:recv_proxy_header/2
This is the function that should be called regardless of
TCP or TLS being used. The proper usage for this function is:
{ok, ProxyInfo} = ranch:recv_proxy_header(Ref, Timeout),
{ok, Socket} = ranch:handshake(Ref),
...
Ranch takes care of everything else under the hood. Transports
now need to have a Transport:recv_proxy_header/2 function. For
ranch_ssl the function gets the port from the sslsocket() record
and then calls ranch_tcp:recv_proxy_header/2 with it.
This means that two undocumented features are currently used for
this, but the interface is really nice so that's a sacrifice
worth doing. Also worth noting is that OTP 22 should have an
alternative for gen_tcp:unrecv/2 so the only real issue is about
the sslsocket() record at the moment.
