5f557f3c1b README.mux: add info about Demux API and vwebp
Also use a naming 'extended format' rather than 'container file' to be
consistent with the container specification.

a00a3daf5b Use 'frgm' instead of 'tile' in webpmux parameters
- Also, use the term 'fragments' instead of 'tiling' in code
- This makes code consistent with the spec.

Also,

- Use WebPData for storing data in WebPChunk.
- Fix a potential memleak.

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.
