mod_proxy65: Consistently apply authorization checks
The module checked for authorization when a client asked for the address:port
of the proxy service. It did not check for authorization when processing a
request to activate a bytestream. This meant that any unauthenticated party
able to guess the IP/port and XMPP domain of a proxy65 service (generally low
difficulty) would be able to use the proxy to relay traffic between two
connections.
This factors out the permission check, and applies it to every request type.
