The used value should not matter as long as its within the array
as it is multiplied by 0

This also fixes linking failures in doc/examples which where apparently
caused by the linking order between avcodec and avresample

Fate tests pass with both avresample as well as swresample based opus decoder, but
are disabled (reference files are very large so i want to think a day or 2 about
if theres an alternative or if they could be avoided, they also dont match the
official samples)

Opus celt decoding 11% faster and the iMDCT over 2.5 times faster on
Apple's A7.

avcodec might depend on avresample and with --as-needed required symbols
might be get removed if avresample is linked before avcodec.
Fixes link failures of avprobe and avplay on aarch64 with
--enable-neon-clobber-test.

If a non-NULL codec was passed to avcodec_alloc_context3(), private data
will be already allocated in dest.

There should not be any valid reason anymore for passing completely
empty packets to lavf.
OTOH side data-only packets can be useful.
