53e35fd340 ac3enc: add num_rematrixing_bands to AC3EncodeContext and use it instead of the hardcoded value. 
Currently it is always 4, but this change will allow it to be adjusted when
bandwidth-related features are added such as channel coupling, enhanced
channel coupling, and spectral extension.

ff1efc524c threads: allow thread count of zero 
This moves setting the thread count to a minimum of 1 to
frame_thread_init(), allowing a value of zero to propagate
through to the codec if frame threading is not used.  This
makes auto-threads work in libx264.

ad9791e12b pthreads: Fix bug introduced with thread_safe_callbacks 
For intra codecs, ff_thread_finish_setup() is called before decoding starts
automatically. However, get_buffer can only be used before it's called, so
adding this requirement broke frame threading for them. Fixed by moving the
call until after get_buffer is finished.

7e06e0ede3 dca: use EXT_AUDIO_ID field to determine core extensions 
This avoids the core substream extensions scan when the EXT_AUDIO_ID
field indicates no extensions or only unsupported extensions. The scan
is done only if the value of EXT_AUDIO_ID is unknown or indicates a
present XCh extension which we can decode.

bbfd2e7ab4 VC1: inline vc1_put_block() in vc1_decode_i_blocks(). 
Advantage is that it allows us to combine several loops into a single
one, and these can eventually be merged into the IDCT itself. Also, it
allows us to remove vc1_put_block(), and makes CODEC_FLAG_GRAY faster.

70aa916e46 VC1: don't use vc1_put_block() in vc1_decode_i_blocks_adv(). 
Advanced profile never uses "range reduction", so vc1_put_block() quite
literally just calls put_pixels_clamped() from vc1_decode_i_blocks_adv().
By inlining the function, we can prevent calling IDCT8x8 if
CODEC_FLAG_GRAY is set, and we don't have to scale the coeffs in the
[0,256] range, but can instead use put_signed_pixels_clamped().
