Make FlexFEC packets paceable through RTPSender.

Browse Source 
Prior to this change, FlexFEC packets that were paced would be lost in
the RTPSender, since they were not stored in a packet history. This CL
introduces such a packet history, as well as the needed wireup for
higher layers to be aware that the particular RTPSender is able to
send FlexFEC packets with a particular SSRC.

Updated RTPSender unit test to reflect the fact that paced packets
are now actually sent.
