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.

- 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

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.

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'"

- Fix the off-by-one diff when cropping with simple-filter.
- Fix a bug in incremental decoding in case of alpha.
- In VP8FinishRow(), do not decode alpha when y_start > y_end.
- Correct output of alpha channel for MODE_ARGB.
- Correct output of alpha channel for MODE_RGBA_4444.

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
