514d008921 add dsp/lossless.[hc] from experimental
Pulled from the current HEAD (218c32e).
The history of this and related files is a bit entangled so rather
trying to split the changes and introduce some noise in master's history
we'll start with a fresh snapshot.
The file progression is still available in the experimental branch.

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

ba503fdac6 NEON TransformOne
As with the loop filter, implementing this with intrinsics is difficult
because we require subscript access for reading and writing 32 bits at a
time.

Approximately 5% decode speed improvement. This could be increased by
exposing TransformOne and rewriting TransformTwo to only handle dual
IDCTs.

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
