This moves the cpu flag parsing code from avconv to avutil so
it can be accessed elsewhere.

This allows masking CPU features with the -cpuflags avconv option
which is useful for testing different optimisations without rebuilding.

The were broken since August of 2010 without anyone noticing until
three weeks ago. Nobody cares about it anymore and hopefully Marvell
will support NEON like in the PXA978 from now on.

Some MMX-only CPUs do not have support for CMOV.
All SSE/MMX2 CPUs should be fine, thus no check was
added to those functions.

Add missing multiple inclusion guards; clean up #endif comments;
add missing library prefixes; keep guard names consistent.

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.

Instead of defining functions in per-arch header files included
by the main cpu.c, define them normally and call them from the
generic one.
