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.

565a2cab22 Makefile.vc: rule maintenance
Remove the bulk of xcopys from the TARGET rule as things are built to
the correct location.
Allow the clean rule to be appended and only delete DLLINC for dll
builds to avoid prompting by erase when it's undefined.

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

Currently the -noasm switch in the examples will be disabled for these

19db59f80f add support for RGB565, ARGB4444 and ARGB colorspace (decoder)
RGB565 and ARGB4444 are only supported through the advanced decoding API.
ARGB being somewhat generic, there's an easy WebPDecodeARGB()
new function for convenience.

d260310511 add Advanced Decoding Interface
You can now use WebPDecBuffer, WebPBitstreamFeatures and WebPDecoderOptions
to have better control over the decoding process (and the speed/quality tradeoff).

WebPDecoderOptions allow to:
 - turn fancy upsampler on/off
 - turn in-loop filter on/off
 - perform on-the-fly cropping
 - perform on the-fly rescale
(and more to come. Not all features are implemented yet).

On-the-fly cropping and scaling allow to save quite some memory
(as the decoding operation will now scale with the output's size, not
the input's one). It saves some CPU too (since for instance,
in-loop filtering is partially turned off where it doesn't matter,
and some YUV->RGB conversion operations are ommitted too).

The scaler uses summed area, so is mainly meant to be used for
downscaling (like: for generating thumbnails or previews).

Incremental decoding works with these new options.
More doc to come soon.

dwebp is now using the new decoding interface, with the new flags:
  -nofancy
  -nofilter
  -crop top left width height
  -scale width height

00d9d6807c swig: file reorganization
Rather than %include'ing decode.h and potentially pickup new
(unsupported functions), explicitly list the desired functions as with
encode.
Reorganize a bit to contain most of the language specific additions to
one area. This fixes the visibility of the wrap_* functions in java. The
method modifiers need to come before the function prototypes.

40a7e347ff dec/dsp: disable sse2 for Visual Studio builds
This is a temporary workaround for issue #80.

Currently dec/dsp_sse2 is not included in Makefile.vc. Simply adding it
will cause a build error, however, as cl does not support aligning
function parameters producing, e.g.,
src\dec\dsp_sse2.c(228) : error C2719: 'q1': formal parameter with
__declspec(align('16')) won't be aligned
