5effc83479 update FSF addresses to FSF web page 
FSF addresses used in PA sources are no longer valid and rpmlint
generates numerous warnings during packaging because of this.
This patch changes all FSF addresses to FSF web page according to
the GPL how-to: https://www.gnu.org/licenses/gpl-howto.en.html

1319c4533a core: Add ARM NEON optimized sample conversion code 
final:
* includes some minor style fixes and build-time changes to allow
  building a single binary for neon and non-neon systems
v4:
* fix for sample length < 4
v3:
* convert from intrinsics to inline assembly
v2:
* load and store data with vld1/vld1q and vst1/vst1q, resp., to work
  around alignment issues of compiler-generated vldmia instruction
* remove redundant check for NEON flags

Ubuntu/Linaro gcc 4.6.3

conversion may be off by one for some samples due to rounding issues

60660a1aec core: Separate ARM CPU detection from initialisation 
This separate the ARM CPU feature detection code from the initialisation
so that we can reuse it in tests, like we did for x86 a while back.

ab4223e9cf cpu: Add CPU information to pa_core 
This retains CPU information (processor type and supported features) in
pa_core, so that this information can be used by modules at init time to
figure out what optimisations may be used.
