fdbe02c581 windows: match _cond_destroy logic w/return variable name
CloseHandle returns non-zero on success so earlier versions would leave
'ok' with a misleading value, though the return itself was correct.

dcfa509a28 Fixed recursive inclusion of bit_writer.h and vp8enci.h.
Was getting compiler error when I included bit_writer.h from non libwebp
directory. bit_writer.h includes vp8enci.h and that uses VP8BitWriter without
having it's definition.

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

ebeb412aa5 use unsigned int for bitfields
uint8_t is a gcc extension which msvc similarly supports, but for
greater compatibility, and to match the change already made in
dec/vp8i.h, update the remaining bitfield to use unsigned int.

Pascal Massimino
900286e091 add a -partition_limit option to limit the number of bits used by intra4x4
Although it degrades quality, this option is useful to avoid the 512k
limit for partition #0.
If not enough to reach the lower bound of 4bits per macroblock header,
one should also limit the number of segments used (down to -segments 1)

See the man file for extra details.

James Zern
473ae95324 fix hang on thread creation failure
with assertions enabled the code would abort in
WebPWorkerChangeState with:
Assertion `worker->status_ >= OK'

without them the code would hang in the _cond_wait.

this change makes WebPWorkerChangeState a no-op in this case.

fc7815d692 multi-thread decoding: ~25-30% faster
To be enabled with the flag WEBP_USE_THREAD.
For now it's only available on unix (pthread), when using Makefile.unix
Will be switched on more generally later.

In-loop filtering and output (=rescaling/yuv->rgb conversion)
is done in parallel to bitstream decoding, lagging 1 row behind.

Example:
examples/dwebp bryce.webp -v
Time to decode picture: 0.680s

examples/dwebp bryce.webp -v -mt
Time to decode picture: 0.515s
