rtcp_cleanup_clients - Permanently remove clients from the list Permanently delete struct rtcp_client_t from member list when it is there time to be removed.

RFC 3550 recommends a grace period of five times the RTCP packet send/receive interval before permanent removal of session. This is to ignore out of order packets for the same SSRC that arrive after the BYE report for that SSRC has been received. Arguments:

Parameters:

p_this

	rtcp_event	type of event received
	b_sender	are we the sender or the receiver
	*b_first	the first time this function is called use only half of the initial waiting time. If b_first is true, then it will return *b_first = false;
