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.

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
