- 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.

Add WebPDataCopy and use it in ReadImage which now returns WebPData*s.
Update ReadData prototype variables used with it to avoid unnecessary
const casting back and forth from void*.

- send errors to stderr
- send help to stdout
- add image size to webpmux -info output and send to stdout
- correct webpmux exit values

- Support for adding/getting frames/tiles with alpha in webpmux
- For "-info" option in webpmux binary, add alpha related info
Change-Id: Iccd2fd35ab8453dabd74779f12f2844ab76d0538
- 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.
