e0febda22d h264: stricter reference limit enforcement.
Progressive images can have only 16 references, error out if there are
more, since the data is almost certainly corrupt, and the invalid value
will lead to random crashes or invalid writes later on.

48cbe4b092 h264: increase reference poc list from 16 to 32.
Interlaced images can have 32 references (16 per field), so limiting the
array size to 16 leads to invalid writes.

cdf9108b6a rtsp: Resend new keepalive commands if they used stale auth
These commands are sent asynchronously, not waiting for the reply.
This reply is parsed later by ff_rtsp_tcp_read_packet or
udp_read_packet. If the reply indicates that we used stale
authentication and need to use a new nonce, resend a new keepalive
command immediately.

This is the only request sent asynchronously, so currently there's
no other command that needs to be resent in the same way.

3aa661ec56 h264: improve parsing of broken AVC SPS
Parsing the entire NAL as SPS fixes decoding of some AVC bitstreams
with broken escaping. Since the size of the NAL unit is known and
checked against the buffer end we can parse it entirely without buffer
overreads.
