This commit moves the minimum bits per slice calculations outside of the
rate control function as it is identical for every slice.

Since coefficients differ only in the last bit when writing to the
bitstream it was possible to remove the sign from the tables, thus
halving them. Also now all quantization is done in the unsigned domain
as the sign is completely separate, which gets rid of the need to do
quantization on 32 bit signed integers.

Overall, this slightly speeds up the encoder depending on the machine.
The commit still generates bit-identical files as before the commit.

The plugin loaded may not match the general implementation capability
wise.

Consistent with what we already do with subtitles since ac08c5c0ad.

Fixes auto-detection for some resolutions.

Fixes build of lavd/jack on linux if dispatch happens to be available on
this platform. dispatch, as well as its dependencies kqueue and pwq are
generally not installed / distribued on linux systems. If it happens to
be the case, you want to explicitely link against the libraries (using
-ldispatch) as opposed to darwin where it is part of the standard
library and -ldispatch doesn't work.

It currently just calls av_init_packet(), which does not touch those
fields.

This will be useful in the following commits.

Do not pass just a bare AVFormatContext pointer around, wrap it in
struct. This will be useful in the following commits.

avprobe is not doing any decoding, so this is more correct than printing
information from a random codec implementation.

AVStream.codec is always non-NULL

Also, remove a stray line (apparently fallout from conflict resolution).

This avoids accessing NULL pointers in case of error.

The deinit function in the 'error' section will correctly free
everything.

Fixes ticket #5267.

Some containers, like webm/mkv, will contain this mastering metadata.
This is analogous to the way 3D fpa data is handled (in frame and
packet side data).
