Do not send RTP to port 0
Previously it was possible to send RTP data to port 0. This produce
multiple errors during the beginning of RTP transmission.
To address this OSMO_RTP_F_DISABLED flag was introduced. It's set by
default for all new RTP sessions. It can be manually unset after the
call to osmo_rtp_socket_create(). When the flag is set it prevents
transmission and reception of RTP frames for the session. The flag is
unset automatically in osmo_rtp_socket_connect() when session is bound
to non-zero remote port.
Fixes: OS#1662
