It is not used anymore and is a kludge.

According to its description, it is supposed to be the LCM of all the
frame durations. The usability of such a thing is vanishingly small,
especially since we cannot determine it with any amount of reliability.
Therefore get rid of it after the next bump.

Replace it with the average framerate where it makes sense.

FATE results for the wtv and xmv demux tests change. In the wtv case
this is caused by the file being corrupted (or possibly badly cut) and
containing invalid timestamps. This results in lavf estimating the
framerate wrong and making up wrong frame durations.
In the xmv case the file contains pts jumps, so again the estimated
framerate is far from anything sane and lavf again makes up different
frame durations.

In some other tests lavf starts making up frame durations from different
frame.

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

It's only used by raw demuxers for storing the codec id.

None of the raw audio files have timestamps, thus setting
start_time to 0 should be reasonable.

It's not supposed to be set outside of lavc. Set r_frame_rate and
avg_frame_rate instead.

It's supposed to be called only from (de)muxers.

Put the new raw GSM demuxer in its own file.
Fixes raw GSM demuxing.

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

The demuxer does not read the seektable, a parser is not possible without a
full decode, and no shorten decoder can handle random seeking because it needs
side info from the seektable.

This is a raw demuxer for the AAC LATM decoder and thus limited to
single stream LOAS.

pixel_format/video_size only apply to 'rawvideo' (==uncompressed) demuxer
and make no sense for the other raw (== containerless) demuxers. Keep
only the framerate option for those.

Also use unique classes for all raw video demuxers

AVFormatParameters are converted into corresponding private options in
av_open_input_file/stream() compat wrappers, so accessing them from
demuxers is redundant.

It's more readable and less prone to breakage.

It's simpler and less error-prone.

Fixes some memleaks along the way.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.
