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.

Make FF_DEBUG_DCT_COEFF output coeffs via av_log() instead of just via AVFrame.
This allows the values to be used without changing C code and is closer to how
the other DEBUG flags work.
If this causes a problem for any user of this flag, please tell me and
ill split the flag in 2.

VC1: inline vc1_put_block() in vc1_decode_i_blocks().
Advantage is that it allows us to combine several loops into a single

allows us to remove vc1_put_block(), and makes CODEC_FLAG_GRAY faster.
