Add ranch_tcp:recv_proxy_header/2
This uses the undocumented function gen_tcp:unrecv/2.
Tests have been added for both gen_tcp and ssl connections,
including sending data in the same first packet, at least
for gen_tcp (ssl tests may or may not end up buffering some
of the TLS handshake before the recv call, but there's no
guarantees).
