Avoid pextrw, since it's slow on many older CPUs.
Now it doesn't require mmxext either.

The new library is meant to contain the core multimedia utilities for
FFmpeg, to make them shareable between more libav* libraries.

darwin requires _DARWIN_C_SOURCE to be defined for MAP_ANON, which is used by
swscale to determine whether to use malloc() or mmap(). 64-bit darwin does not
have an executable heap, so mmap() must be used instead of malloc(), and
therefore _DARWIN_C_SOURCE must be defined.

The ff_inverse table is used by FASTDIV macro, defined in libavutil, but up
to now the table was defined only in libavcodec.

After this change, the main copy of ff_inverse is part of libavutil (just
like FASTDIV), but if CONFIG_SMALL is unset, then a different copy is made
available to libavcodec, to avoid the performance penalty of using an
external look up table.

Dynamic linking works, because the libraries are linked with -Bsymbolic, so
the local copy of the symbol has priority over the external; static linking
works because the table is on a standalone object file in both libraries,
so the linker is able to discard one of the two.

Tested on Linux/x86-64 and Mac OS X/x86-64.
