f62d2c9497 remove unused 'has_alpha' from VP8GetInfo() signature
alpha information is not to be found at RIFF chunks level, not
in the VP8 bitstream (that was a tmp hack)

c398f59536 MUX API Updates
- Add alpha support in mux.
- Remove WebPMuxAddNamedData() and WebPMuxGetNamedData() APIs. Add WebPMuxSetImage(), WebPmuxGetImage() and WebPMuxDeleteImage() APIs instead.
- Refactor code using WebPImage struct.
- Corresponding changes in webpmux binary.
- WebPMuxSetImage()/AddFrame()/AddTile() can now work with data which starts from "RIFF...". This simplifies reading a single-image webp file and adding it as an image/frame/tile in mux.

9f761cfae9 Changed function signature for WebPMuxCreate
Changed function signature of method WebPMuxCreate and few other minor nits.
Header file has been re-organised to have declaration of set/get/Delete
methods for different use-cases (Metadata, ColorProfile etc) in one place
instead of declaring all Set methods together followed by Get & Delete.
