00c3b67b8a cosmetics: Align codec declarations
Also break some long lines, remove codec function placeholder comments
and add spaces in sample/pixel format lists.

bb03b6f7b1 g722enc: use AVCodec.encode2()
FATE reference updated due timestamp rounding because of resampling from
44100 Hz to 16000 Hz in avconv.

b087ce2bee g722: Fix the QMF scaling
This fixes clipping if the encoder input used the full 16 bit
input range (samples with a magnitude below 16383 worked fine).
The filtered subband samples should be 15 bit maximum, while
the code earlier produced them scaled to 16 bit.

This makes the decoder output have double the magnitude
compared to before.

The spec reference samples doesn't test the QMF at all, which
was why this part slipped past initially.

77c5b66cbe g722enc: set frame_size, and also handle an odd number of input samples
The fate reference is updated because the previous test skipped a sample in
each encode() call due each input frame having an odd number of samples.

f32fd31858 g722: Change bits per sample to 4
Earlier, bits per sample was defined as 8, since
bits_per_coded_sample was used to indicate whether to ignore
the lower bits of the codeword, having values 6, 7 or 8.

g722 encodes 2 samples into one byte codeword, therefore the
bits per sample is 4. By changing this, the generated timestamps
for streams encoded with g722 become correct.

This makes timestamp generation for g722 data correct (both when
encoding and when demuxing from raw g722 files).
