650ffa3bbb add version getters for decoder and encoder
WebPGetDecoderVersion() and WebPGetEncoderVersion()
will not return 0.1.2 encoded as 0x000102

dwebp and cwebp also have a new "-version" flag

f61d14aabf 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'

6421a7a4fb move the decoder sourcetree to a sub-location src/dec
to make room for future libs sources

also extract the types declaration into its own types.h file

a9b3eab6fd correct layout name is IMC4.
U-plane comes first, then V-plane.
see http://www.fourcc.org/yuv.php#IMC4

f67b5939ad 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
