This shrinks the tool manuals to a manageable size. Relevant manuals are
referenced in the "See Also" chapter.

Overall documentation inclusion should still be possible through the use
of a conditional variable set during configuration time, if someone feels
the need for a huge-wall-of-text-fashioned manual.

The metadata muxer/demuxer belongs to the formats documentation.

This fixes the colour of the transparent background (as seen with ffplay),
and makes the background of some non-keyframes transparent that was
incorrectly shown as opaque for some samples.

After demuxing, data and side are merged. Before decoding, they are
split. Encoder will perform with data and side split. This means that a
muxer can receive split data (after encoding) but also merged data (if
called directly after demuxing). This commit makes sure data and side
are split for the muxer.

with this change QuickTime is able to play u8 aiff file generated by FFmpeg

Across the many retouches those did not make the main commit.

Move some functions from dsputil. The idea is that videodsp contains
functions that are useful for a large and varied set of video decoders.
Currently, it contains emulated_edge_mc() and prefetch().

The sample rate and channel layout are negotiated and set
by the filter graph system.

The sample rate and channel layout are negotiated and set
by the filter graph system, the filters must not set them.

Also: fix af_pan and af_aresample, that forgot to update
audio->channels.

impossible if writing to a pipe or network stream. Don't write header
