ortp: resynchronize rtp session on timestamp changes

When libortp detects a timestamp jump, we resynchronize the session
in order to restore proper rtp frame reception. However, we do not
resynchronize on an SSRC change. An SSRC change usually indicates
the change of an RTP stream source, which is a much more profound
event than a timestamp change, so we should even reset the session
on SSRC changes.

Also, not resynchronizing the session on an SSRC change causes
problems when the jitter buffer feature is used. In those cases
it takes libortp a long time until it finally detects the timestamp
jump and the session resyhcornization happens late.

- reset the ession on SSRC changes by calling rtp_session_reset()
