a085cfa654 avformat/utils: Move ff_get_extradata to demux_utils.c 
It is only used by demuxers (although it is hypothetically
possible that some day e.g. a protocol might need it, but
that is unlikely given that they don't deal with AVCodecParameters).

c1e439d7e9 avformat: Forward errors where possible 
It is not uncommon to find code where the caller thinks to know better
what the return value should be than the callee. E.g. something like
"if (av_new_packet(pkt, size) < 0) return AVERROR(ENOMEM);". This commit
changes several instances of this to instead forward the actual error.

ee5f0f1d35 rsd: limit number of channels 
Negative values don't make sense and too large values can cause
overflows. For AV_CODEC_ID_ADPCM_THP this leads to a too small extradata
buffer being allocated, causing out-of-bounds writes.
