a WebP encoder
...
converts PNG & JPEG to WebP
This is an experimental early version, with lot of room
of later optimizations in both speed and quality.
Compile with the usual `./configure && make`
Command line example is examples/cwebp
Usage:
cwebp [options] -q quality input.png -o output.webp
where 'quality' is between 0 (poor) to 100 (very good).
Typical value is around 80.
More encoding options with 'cwebp -longhelp'

lot of cosmetics

just flushing the pile:
- get rid of Put4 in dsp.c
- move LD4 enum value
- move more fields and code under the ONLY_KEYFRAME_CODE compile flag
- update test_ref.ppm reference (now with FANCY_UPSCALER)
- simplify VP8GetSignedValue()
- use HE and VE naming for prediction mode instead of H and V
- some missing c89 fixes
- code style nits
all test vectors still passing
