avformat/id3v2: Fix double-free on error
...
ff_id3v2_parse_priv_dict() uses av_dict_set() with the flags
AV_DICT_DONT_STRDUP_KEY and AV_DICT_DONT_STRDUP_VAL. In this case both
key and value are freed on error (and owned by the destination
dictionary on success), so that freeing them again on error is a
double-free and therefore forbidden. But it nevertheless happened.
Fixes CID 1452489 and 1452421.

avformat/vividas: Check and require 1 video stream
...
The decoder hardcodes that audio is stream_id = 1 so it does not
currently work with more or less than 1 video stream at st=0

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.

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.
