    Fix debugging messages generated by 'udptl debug'.
    
    * Makes chan_sip set the tag to the channel name.
    
    * Fixes received debug message sequence number.
    
    * Removed tx/rx debug message type since it was hard coded to 0.
    
    * Made udptl.c logged message header consistent if possible: "UDPTL (%s): ".
    
    * Removed unused rx_expected_seq_no from struct ast_udptl.
