...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

* make the 'all' target really build everything (default is still the
core examples).
* add demux/mux.h to HDRS_INSTALLED, install the corresponding libs
too
* install vwebp, webpmux, gif2webp and related manpages

-> 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.)

- 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.

The binaries should have dependency on related libraries only.
For example, 'vwebp' sould not depend on libpng, libjpeg etc.

- Separate out mux.h and demux.h
- muxtypes.h: new header for data types common to mux/demux
- Move some misc read/write utilities to utils/utils.h
- Remove some duplicate methods.
- Separate out mux/demux libraries

this target is experimental so must be explicitly set
missing since:
e41a759 build: remove libwebpmux from default targets/config
Change-Id: I128d9e6a06ba3e7102ae3175dc3db52c6f4b1439
the extended file format is still under development and related
libs/binaries are not fit for release
configure:
--enable/disable-libwebpmux; default is disabled.
makefile.unix:
src/mux/libwebpmux.a and examples/webpmux must be explicitly specified
Makefile.vc:
$(DIRLIB)\libwebpmux.lib and $(DIRBIN)\webpmux.exe must be explicitly
specified

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)
broken since:
48f8275 add colorspace for premultiplied alpha

* Method #1 is now calling the lossless encoder on the alpha plane.
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

Add predictive filtering option for Alpha plane.
Valid range for filter option is [0, 5] corresponding to prediction
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.
