Move get_logical_cpus() from lavc/pthread to lavu/cpu.
...
It will be useful in lavfi, and could conceivably be useful to the user
applications as well.

x86: build: replace mmx2 by mmxext
...
Refactoring mmx2/mmxext YASM code with cpuflags will force renames.
So switching to a consistent naming scheme beforehand is sensible.
The name "mmxext" is more official and widespread and also the name
of the CPU flag, as reported e.g. by the Linux kernel.

ARM: allow runtime masking of CPU features
...
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.

Add a CPU flag for the Atom processor.
...
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.
