Fix no_size_t_to_int_warning in rtp_rtcp:rtp_rtcp_format target by danilchap@webrtc.org - https://webrtc.googlesource.com/src/webrtc/+/bb11e12079726753f08094ed9dca8dc52c98dfea

Remove RtpPacketToSend::GetHeader as almost unused. by danilchap@webrtc.org - https://webrtc.googlesource.com/src/webrtc/+/1f4668043e639759ad998c0849c5e6e242008e1d

If this is incorrect, please let us know why and apply the Test-Predator-Wrong-CLs label.

To trigger incoming packet has to be > 64k, but packets larger than > 1500 are discarded earlier in the pipeline. Thus reducing priority.

Skip oversized rtp header extension when parsing Rtp Packet.

Rtp Packets in webrtc expected to be less that 1500,
i.e. way less that 2^16 bytes for extensions block.
This CL explicitly discards longer extension.
