The header is always required for files which directly deal with
devices, since libavdevice uses the AVFormat* structures defined in
avformat.h.

Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems
since it causes certain system functions to be hidden on some (BSD) systems.
The solution is to only add the flag on systems that really require it, i.e.
glibc-based ones.
This change makes BSD systems compile out-of-the-box without the need for
adding specific flags manually. It also allows dropping a number of flags
set manually on a file-per-file basis, but were only present to work around
breakage introduced by the presence of _POSIX_C_SOURCE.
Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions
in several places already, so it is preferable to define it globally instead
of littering source files with individual #defines only needed for glibc.
* qatar/master:
APIChanges: document git revision for CODEC_CAP_SLICE_THREADS addition.
Introduce slice threads flag.
FATE: allow forcing thread-type when doing threaded fate runs.
Use av_log_ask_for_sample() where appropriate.
error: sort, pack, and align error code and string definitions
The stabilization period after version bumps should be one month, not one week.

audio for recording, do not fail just because the endianness is not

It is possible that 8-bit recording would not have worked at all on
some systems without that change.

Currently, only S16 quad, 5.1 and 7.1 are implemented.
Implementing support for other formats/layouts and capture should be
straightforward.
7.1 support by Carl Eugen Hoyos.
In fbdev_read_packet(): nanosleep returns -1 in case of errors,
the EINTR check has to be done on errno.

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

This also lists the objects from those two libraries as internal (by adding
the ff_ prefix) so that they can then be hidden via linker scripts.
(cherry picked from commit c6610a216e)
timebase value already set in the driver, and set it back in the codec
stream, rather than leaving the invalid value of 0/0.
In particular, fix ffmpeg grabbing timestamps when the timebase value
is not set through the CLI.
Originally committed as revision 26224 to svn://svn.ffmpeg.org/ffmpeg/trunk
This new version:
1. Works on 24-bit and 32-bit input, not just 32-bit.
2. Doesn't try to run on 16-bit or 8-bit, instead of outright crashing.
3. Does proper alpha-blending, so cursor shadows look correct.
4. Doesn't swap R and B.
Mostly fixes issue 1997.
Fixes issue 2056.
