It is supposed to be used with different bit depth and/or sample rates
per each substream, but such currently not implemented feature is not
important and current state causes problems when implementing variable
restart interval to fix decoding with sample rates not multiple of 40.
This reverts commit 628a73f8f3.
At the time of said commit there was talk of removing the audio bitrate
"ab" option to bring FFmpeg in line with what Libav has done in 2012 in
commit 041cd5a0c5. By having different
option flags for the "ab" and the ordinay bitrate "b" option is is
possible to have different default bitrates for audio and video. In
order to maintain this behaviour and not break user scripts the commit
to be reverted added code to ffmpeg.c that set the bitrate value to the
audio default for audio codecs, but only if AVCodec.defaults didn't
exist (as in this case the default would be codec-default and not
affected by the "ab" removal).
This had the downside of being an API violation, because
AVCodec.defaults is not a public field. Given that the "ab" option
and its audio-specific default value have never been removed,
said API violation can be simply fixed by reverting said commit.

This way the CLI accepts for "filter_threads" the same values as for the
libavcodec specific option "threads".
Fixes FATE with THREADS=auto which was broken in bdc1bdf3f5.

The earlier code did not properly check these initializations:
It only recorded whether the part of init where these initializations
are has been reached, but it did not check whether the initializations
were successful, although destroying them would be undefined behaviour
if they had not been initialized successfully.
Furthermore cleanup() always locked a mutex regardless of whether there
was any attempt to initialize these mutexes at all.

Now that the mutexes and conditions are only initialized and destroyed
once, said function only had one purpose: free the entries array.
Given that vp9_alloc_entries() already does this if the array is already
allocated it is unnecessary to call vp9_free_entries() anywhere except
when closing. And then one can just inline the one free into
vp9_decode_free().
