Philipp Hancke 949d3c9acf Reland "h264: fix first_packet_in_frame logic for multislice in a single rtp packet"
This reverts commit bdc669347c70160cd648f5cab7a417227d41d82a.

Reason for revert: AUDs will be taken into account now.
video_replay with the provided out.pcap and these options:
--codec H264 --input_file out.pcap --media_payload_type 102 --ssrc 40000
plays smoothly.
