Additionally use the correct error number.

Raw audio does not provide valid audio tags while rawvideo does.
The fate refs have to be updated because it undoes the previous tag
change.

Use native tags instead of avi ones, simplifies a lot raw video codecs
handling.

While a 25 fps stream can in general store frame durations in 1/25
units, this is not true for the timestamps. For example a 25fps
and a 25000/1001 fps stream when they are stored together might have
a matching 0 timestamp point but when for example a chapter from
this is cut the new start is no longer aligned. The issue gets
MUCH worse when the streams are lower fps, like 1 or 2 fps.

This commit thus makes the muxer choose a multiple of the
framerate as timebase that is at least about 20 micro seconds precise

With this, when we use a finer timebase than neccessary to store
durations the demuxer still knows what the original timebase was.

This way audio frames can be exactly stored even when they are not
aligned with timestamp 0

This is consistent with stdio and is what we want to do in all cases.

Fixes a bug in the voc muxer which didn't flush in write_trailer()
previously. This is the cause of the change in the test results.

The seek test improves in accuracy
Fixes Ticket877

This removes the use of macro nesting in these code constructs, which
makes it easier to parse in pre-processors.

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

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

Specifically, ff_mpa_freq_tab, ff_mpa_bitrate_tab, ff_mpa_decode_header,
ff_mpegaudio_decode_header.

Rename write_{header,packet,trailer} to nut_write_{header,packet,trailer}
in order to make easier debugging them.

It's more readable and less prone to breakage.
