3527a73933 avutil: add av_parse_cpu_flags() function 
This moves the cpu flag parsing code from avconv to avutil so
it can be accessed elsewhere.

d526c5338d 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.

363bd1c62c remove iwmmxt optimizations 
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.

eba586b0d9 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.

9275438a19 Clean up av_get_cpu_flag() 
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.
