Summary:                    [patch] Retransmitted RFC 2833 RTP events do not
increment the RTP sequence number
Description: 
All 3 retransmitted ending packets share the same sequence number, which
does not comply with RFC 4733 Sect. 2.5.1.6. RTP Sequence Number:

   The RTP sequence number MUST be incremented by one in each successive
   RTP packet sent.  Incrementing applies to retransmitted as well as
   initial instances of event reports, to permit the receiver to detect
   lost packets for RTP Control Protocol (RTCP) receiver reports.

This patch fixes the issue, as well as remove an unneeded (duplicated) line
to set the first part of the RTP header which has the marker bit set (?).
