df08e67e06 dsp/cpu: add AVX detection
currently unused.
https://software.intel.com/en-us/articles/introduction-to-intel-advanced-vector-extensions

similar checks exist in ffmpeg, libyuv. the visual studio inline asm is
based off of libyuv.

d640614d54 update copyright text
rather than symlink the webm/vpx terms, use the same header as libvpx to
reference in-tree files

255c66b48f Android: only build dec_neon with NEON support
Defining LOCAL_ARM_NEON = true can result in neon instructions being
used in portions unprotected by the cpu check.
This changes defines a WEBP_USE_NEON/WEBP_ANDROID_NEON pair similar to
the SSE2 code and MSVC.

834f937f3c dsp/cpu.c: Android: fix crash on non-neon arm builds
add proper cpu-detection for Android targets

Fixes issue #118 (and is a better solution for #117).

a0b2736d79 cosmetics & warnings
- remove some unused functions
- move global arrays from data to read only section
- explicitly cast malloc returns; not specifically necessary, but helps
  show intent
- miscellaneous formatting

e4e3ec19ad fix gcc-4.0 apple 32-bit build
gcc-4.0 defines __PIC__ but not __pic__. This leaves the test for
__pic__ should the inverse case exist.
Fixes issue #103; build failing with:
"error: can't find a register in class 'BREG' while reloading 'asm'"

e06ac0887f create a separate libwebpdsp under src/dsp
Gathers all DSP-related function (and SSE2 implementations).
Clean-up some unwanted symbolic dependencies so that webp_encode,
webp_decode and webp_dsp are truly independent libraries.

+ opportunistic clean-up:
  * remove unneeded VP8DspInitTables(), now integrated in VP8DspInit()
  * make consistent use of VP8GetCPUInfo() in the various DspInit() funcs
  * change OUT macro to DST
