Subject: [PATCH] Use c2s state data as user and server in
 ejabberd_c2s:is_privacy_allow

is_privacy_allow is only used in ejabberd_c2s:handle_info/3 to determine
for a few presence types whether the packet is allowed to be forwarded
to the user's client. This only makes sense if To#jid.user and
To#jid.server match StateData#state.user and StateData#state.server.

Also, add the atom in as parameter to a new argument Dir of
is_privacy_allow and extract from that function
privacy_check_packet(StateData, From, To, Packet, Dir) which runs the
privavcy check without converting allow/deny to true/false.
