AVERROR_NUMEXPECTED is used only in the image muxer and demuxer, and
has a too much specific meaning, which is better explained through a
log message. Thus it can be replaced by AVERROR(EINVAL).
This breaks API.

The new error code is better than AVERROR(ENOENT), which has a
completely different semantics ("No such file or directory").

When attempting to re-enable the AltiVec support it was noticed
that we need to undefine _POSIX_C_SOURCE to appease the headers
for ff_get_cpu_flags_ppc() to be able to compile.

With unknown attribute warnings disabled, these checks are no
longer needed. Removing them improves readability while having
no effect on generated code.

The Atom has SSSE3 support, which is useful in many cases, but sometimes the
SSSE3 version is slower than the SSE2 equivalent on the Atom, but is generally
faster on other processors supporting SSSE3. This flag allows for selectively
disabling certain SSSE3 functions on the Atom.
This is different from AVERROR(EINTR) because calls that fail with EINTR
should usually be restarted.

This allows the CPU detection to work with assemblers not supporting
the xgetbv mnemonic. These include clang and some BSD versions.
All AVX code will be written for yasm, where the main assembler
is not involved.

On some versions of gcc, these weren't always getting inlined due to hitting
the inline cap limit in some files. This is generally bad, as most of these
functions are smaller inlined than not.

The new av_parse_time() is created in libavutil/parseutils.h, all the
internal functions used by parse_date are moved to
libavutil/parseutils.c and made static.

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.
