Justin Ruggles 119974b164 adpcm_ima_wav: process channel-interleaved blocks sequentially rather than simultaneously.
Speeds up the ADPCM IMA WAV decoder by 15-20% overall.

Justin Ruggles 7c287b18a0 adpcm: update reference links
Add Multimedia Wiki link.
Mark dead links with [dead]. Some can still be accessed through archive.org.
Update URLs for pages which have moved.
Replace duplicated links in adpcmenc.c with a note to see the ADPCM decoder
reference documents.

Justin Ruggles ac94b8bcc6 adpcm: simplify packet size bounds checking in the ADPCM IMA QT decoder.
This is easier to understand. It also avoids returning existing samples mixed
with new samples when the packet is too small.

Mans Rullgard bf00a73ace dca: clear inactive subbands only once in qmf_32_subbands()

done once as the cutoff position is constant throughout the
