79ff03460a add proper WEBP_HAVE_GIF and WEBP_HAVE_GL flags
...and make gif2webp and vwebp compile without them.

Makefile.vc still to be updated...
Meanwhile the CL environment variable can be supplemented with

set CL=/DWEBP_HAVE_GL /IC:\opt\freeglut\include

5cf7792e40 split quant_levels.c into decoder and encoder version
-> split libraries further into decoder / encoder
-> add libwebpdecoder.a in Makefile.unix
-> make dwebp link against libwebpdecoder.a in Makefile.unix

also: in makefile.unix, pass EXTRA_FLAGS to LDFLAGS too
(otherwise, -m32 wouldn't work, e.g.)

090b708a00 NEON optimised yuv to rgb conversion
- along the lines of the SSE chroma upsampling.
Total speedup is ~30%.

4% speed loss on YuvToRgbXX conversion using tables instead
of 14-bit fixed precision. TODO(later): investigate, and compare
to x86.

fcec059322 makefile.unix: cwebp: fix OSX link
this is more a workaround than a fix. this change forces the tables
from yuv.h into the data section rather than generating them as common
blocks. prior to this the linkage would fail with e.g.,

Undefined symbols:
...
  "_VP8kClip4Bits", referenced from:
      _Yuv444ToRgba4444 in libwebp.a(libwebpdsp_la-upsampling.o)

Format is not final, it's just a first draft. We need ad-hoc functions.
* removed now useless utils/alpha.*
* added utils/quant_levels.h instead
* removed the TCoder code altogether

methods none, horizontal, vertical, gradient & paeth filter.
The prediction method 5 will try all the prediction methods (0 to 4)
and pick the prediction method that gives best compression.
