3fca851a20 cpu: check for _MSC_VER before using msvc inline asm
_M_IX86 will be defined in mingw builds after including windows.h. as
the gcc inline asm is first, this missing check would only have caused
an error if the code was reorganized.

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

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
