Justin Ruggles c9bca80132 avutil: add AVERROR_UNKNOWN
Useful to return instead of -1 when the cause of the error is unknown,
typically from an external library.

Diego Biurrun b315042c8c Remove libpostproc.
This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

Mans Rullgard cc276c85d1 Make channel layout masks unsigned
It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.

Fixes a few invalid shifts.

Martin Storsjö 627067118c avutil: Add av_timegm as a public function
This is useful, since the normal timegm function isn't a standard
function (requiring _BSD_SOURCE or _SVID_SOURCE on glibc to
be visible, and not available on e.g. windows). The widely available
function mktime uses the local time zone, which requires ugly
workarounds to handle UTC time.

Stefano Sabatini a6703faa15 samplefmt: add av_get_bytes_per_sample()
Deprecate av_get_bits_per_sample_fmt(), which was a misnamed function.

For the moment we don't have sample formats with a non-integer number
of bytes, in that case we may need to create a new
av_get_bits_per_sample() function. In the meanwhile we prefer to adopt
this variant, since avoids divisions by 8 all over the place.
