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.

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
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.

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.

was missing from the RD-computation of intra-4x4 score.
Doesn't change anything significantly, it's just More Correct.

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.

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.

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

(release|debug)-dynamic
These configurations will produce a dll in bin/ and an import lib under
lib/.
Currently the -noasm switch in the examples will be disabled for these
builds due to a dependency on VP8EncGetCPUInfo.

Add WEBP_EXTERN(type) macro which should make Windows DLL builds simpler
by allowing the signature to be changed.

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