Get rid of the "ret" variable, and always use err. Report the packet as
consumed if err is unset. This should be equivalent to the old code,
which obviously required err=0 for p->result>=0 (and otherwise,
p->result must have had the value err was last set to). The code block
added by commit 32a5b631 is also not needed anymore, because the new
code strictly returns err if it's >=0.

Intra-only codecs should either be able to read these items from the
bitstream, or they should be set upon codec initialization. In both
cases, syncing these items at runtime is unnecessary.

In practice, this fixes race conditions for decoders that read these
values from the bitstream.

This prevents a race condition in files with multiple slices per frame.

The patch introduces race conditions.

This allows vp9dsp.h to only include the VP9 types header, and not the
decoder skeleton interface which is for hardware decoders (dxva2/vaapi).

The advantage here is that the internal software decoder interface is
not exposed to the DSP functions or the hardware accelerations.

If ret is NULL, a dummy common holder is created to hold *all* the
parallel function returns, which gets written concurrently. This commit
simplify the whole logic by simply not writing to that holder when not
set.

adding demuxer and other logs should be easy
This forces single threaded decoding for simplicity
It also requires pthreads, this could be avoided either with
some lockless tricks or simply by assuming av_log would never be called from
another thread.
