73a93e8257 Add a ParseHeader method to RtcpPacket, for parsing common RTCP header. 
Also refactor TransportFeedback to use this.

5e023eb337 Add TransportFeedback adapter, adapting remote feedback to bwe estiamtor 
When using send-side bandwidth estimation, the inter-packet delay is
reported back to the sender using RTCP TransportFeedback messages.
Theis data needs to be translated into a format which the bandwidth
estimator (now instantiated on the send side) can use, including looking
up the local absolute send time from the send time history.

c32d2db69b Refactor RTPPacketHistory to use a packet struct. 
Collects packet information within a struct instead of spreading it out
over different vectors. Adds a fixed-size buffer to the stored packet
instead of using vectors.

43e7d3bc15 Avoid overflow in checking for emulation bytes in rbsp. 
Also fixed an arithmetic issue where a 0 0 3 at the end of the rbsp would include the 3 (that's not a legal bitstream anyway, so it probably wasn't a real bug, but it was incorrect).

This maintains the underflow fix from an earlier CL (https://codereview.webrtc.org/1219493004/). The overflow fix is virtually impossible to hit (hence no unit tests), but is there for strict correctness.

c1b9d4e686 Add support for fragmentation in RtcpPacket. 
If the buffer becomes full an OnPacketReady callback will be used to
send the packets created so far. On success the buffer can be reused.
The same callback will be called when the last packet has beed created.

Also made some changes to RawPacket. Buffer will now be heap-allocated
rather than (potentially) stack-allocated, but on the plus side it can
now be allocted with variable size and also avoids one memcpy.
