ab8f1a6989 arm: Fall back to runtime cpu feature detection via /proc/cpuinfo
On recent android versions, /proc/self/auxw is unreadable
(unless the process is running running under the shell uid or
in debuggable mode, which makes it hard to notice). See
http://b.android.com/43055 and
https://android-review.googlesource.com/51271 for more information
about the issue.

This makes sure e.g. neon optimizations are enabled at runtime in
android apps even when built in release mode, if configured to
use the runtime detection.

b57c1da81e arm: detect cpu features at runtime on Linux
This allows compiling optimised functions for features not enabled
in the core build and selecting these at runtime if the system has
the necessary support.

b326755989 arm: rename ARMVFP config symbol to VFP
This is consistent with usual ARM nomenclature as well as with the
VFPV3 and NEON symbols which both lack the ARM prefix.

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.

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.
