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.

Increment the sequence number on the end packets for RFC2833. After
reading the RFC some more and doing some testing I agree with this change.
