2a3ab6f925 move MIN/MAX_HISTO_BITS to format_constants.h 
(under the name MAX_HUFFMAN_BITS, since the specs read:
	int huffman_bits = ReadBits(3) + 2;
)

ff771e7705 don't install webp/decode_vp8.h 
the VP8 decode functions do not need to be public; only
GetInfo/CheckSignature need to be marked extern as they're used by
libwebpmux.

Urvang Joshi
6808e69db8 More spec/code matching in mux: 
- Match offsets, duration, width/height for frames/tiles and enforce
some constraints.
- Note that this also means using 'int's instead of 'uint32_t's for
16-bit and 24-bit fields.

c0e8859d81 Get rid of image_info_ from WebPChunk struct. 
The image_info_ was used only in GetImageCanvasWidthHeight(). So, now
we infer it from data there.
This removal fixes a bug: earlier, 'image_info' wasn't initialized in
the WebPMuxCreate() flow, and so the canvas width/height were being
calculated to be zero.

Also, a related refactoring: Combine CreateImageInfo() and
CreateDataFromImageInfo() into a single function CreateFrameTileData().
