Justin Ruggles 5364327186 adpcmenc: ensure calls to adpcm_ima_compress_sample() are in the right order
Should fix fate-acodec-adpcm-ima_wav with several compilers.

Justin Ruggles d9a13c2f56 adpcmenc: move 'ch' variable to higher scope
It is used for multiple codecs.

Michael Niedermayer aa264da5bf adpcmenc: Calculate the IMA_QT predictor without overflow
Previously, the value given to put_bits was 10 bits long for positive
predictors, even though 9 bits were to be written. The extra bit could
in some cases overwrite existing bits in the bitstream writer cache.

This fixes a failed assert in put_bits.h, when running a version
built with -DDEBUG.

The fate test result gets slightly improved, thanks to getting rid
of the overwritten bits in the bitstream writer cache.

Justin Ruggles 770a5c6d02 adpcmenc: Use correct frame_size for Yamaha ADPCM.
Output packet size should match avctx->block_align. The target output packet
size is 1024 bytes.
Before:
mono   - 1024 samples -> 512 bytes
stereo - 2048 samples -> 2048 bytes
After:
mono   - 2048 samples -> 1024 bytes
stereo - 1024 samples -> 1024 bytes

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.
