This fixes crashes, where the demuxer could return 0 even
if the returned AVPacket isn't initialized at all. This
could happen if running into EOF or running out of probesize
with non-seekable sources.

The mpegts demuxer reads 5 KB at startup just for discovering
the packet size. Since the default avio buffer size is 32 KB,
the seek back to the start will in most cases be within the
avio buffer, and will in most cases succeed even if the actual
protocol isn't seekable.

This makes the demuxer startup faster/with less data when
reading data from a non-seekable input, by not skipping
the first few KB.

If it fails, don't warn if the protocol isn't seekable, making
it behave as before in the failure case.

Also add missing trailing commas, break long codec_tag lines and
add spaces in codec_tag declarations.

This allows it to be used with get_bits without the thread of overreads.

Manual replacements are done in this commit.

In many cases, the id is some constant made up number (e.g. 0 for video
and 1 for audio), which is then not used in the demuxer for anything.
Those ids are removed.

Trivial replacements with sed are done in this commit:
sed 's/av_new_stream(\([^)]*\), 0)/avformat_new_stream(\1, NULL)/'
