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.
