It is used for multiple codecs.

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.

Also break some long lines, remove codec function placeholder comments
and add spaces in sample/pixel format lists.

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

Add FF_INPUT_BUFFER_PADDING_SIZE.
If allocation fails, also free memory which was allocated previously in
adpcm_encode_init().

It is already set in avcodec_alloc_frame().
