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.

NASM versions older than 2.08 fail to build ffmpeg with several
"error: operation size not specified" errors but this is not caught in
configure.

Fix that by checking if "pextrd [eax], xmm0, 1" works in configure.

Recent gcc versions define __ARM_PCS or __ARM_PCS_VFP to indicate the
VFP ABI in use, and ARM RVCT defines __SOFTFP__ when using this ABI.
If none of these are defined, check $cross_prefix and $cc for the
substring "hardfloat", and finally fall back to a linker test.  This
gives the correct result in most configurations.

This macro has unconditionally used .p2align for a long time and
serves no useful purpose.

This is required on systems where the linker does not change
the permissions of an existing output file.

Some linkers fail if this flag is used when creating an executable file.
Since the flag is meaningful only for shared libraries, dropping it from
the main link flags is correct.

This macro is disabled if --enable-small or --disable-optimizations are set.
Currently, this leads to warnings about functions being defined but not used,
for functions in header files.

By defining av_always_inline as inline or as av_unused, we avoid these
warnings.

This doesn't make a normal build with --enable-small any larger,
since the compiler probably chooses not to inline these functions even
if they're marked as inline.
