64d4c90723 avcodec/g729dec: Use 64bit and clip in scalar product
The G729 reference decoder clips after each individual operation and keeps track if overflow
occurred (in the fixed point implementation), this here is
simpler and faster but not 1:1 the same what the reference does.

Non fuzzed samples which trigger any such overflow are welcome, so
the need and impact of different clipping solutions can be evaluated.

Fixes: signed integer overflow: 1271483721 + 1073676289 cannot be represented in type 'int'

38a57d81b3 avcodec/cngdec: Remove AV_CODEC_CAP_DELAY
As is the decoder will never stop, it will cause an infinite loop. The RFC seems only
to speak of non empty packets so endlessly generating noise from the last empty flush
packets seems wrong.

0d816a9471 avformat/nutenc: Do not pass NULL to memcmp() in get_needed_flags()
This compared to the other suggestions is cleaner and easier to understand
keeping the condition in the if() simple.

This affects alot of fate tests.

See: [FFmpeg-devel] [PATCH 05/11] avformat/nutenc: Don't pass NULL to memcmp
See: [FFmpeg-devel] [PATCH]lavf/nutenc: Do not call memcmp() with NULL argument
