This moves some allocations to init, reducing possible failure modes in update.
Always copies from the previous context instead of just during init

The pixel format descriptors are set to more or less arbitrary
values as bayer formats do not fit in the descriptors structure.
These values are currently not used for bayer formats and thus
do not matter.

Merged-by: Michael Niedermayer <michaelni@gmx.at>

Remove the header decoding for PCM audio from mpeg.c and the
20/24bit parts from pcm.c and merge them into a new decoder in
pcm-dvd.c.

The decoder has added support for samples that span multiple
packets and modified 20/24bit group decoding. Both is needed to
decode samples that have been generated with DVD-Lab Pro 2. The
decoding of 16bit PCM and two channel 24bit is identical to
before. No other samples are known to verify the correctness of
the encoding this software does.
The complete list of tested formats is
48kHz/16bit/2-8 channels
48kHz/24bit/2-5 channels
96kHz/16bit/2-4 channels
96kHz/24bit/2 channels
