fbdcb7ea38 NumNamedElements() should take an enum param.
- Move TAG_ID to webp/mux.h
- Rename it to WebPChunkId
- Rename IDs to WEBP_CHUNK_<tag>
- Remove "name" param from ChunkInfo struct and related changes.
- Rename WebPMuxNumNamedElements to WebPMuxNumChunks().
- WebPMuxNumChunks() takes WebPChunkId as param.

069f903a08 Change in lossless bit-stream.
Change the lossless signature to 0x2f
Add 1 bit indicator for 'droppable (or trivial) alpha)'.
Add 3 bit lossless version (for future extension like yuv support).
Change the sub-resolution information to 3 bits implying range [2 .. 9]

c975c44ea5 Alpha flag fix for lossless.
- Make sure alpha flag is set in case of a lossless file with VP8X chunk.
  The semantic of ALPHA_FLAG changes with this: it means the images
  contain alpha (rather than ALPH chunk in particular).
- Update the mux container spec to add 1-line description of alpha
  flag.
- Rename "HasLosslessImages()" to "MuxHasLosslessImages()", and other
  similar function renames.
- Rename FeatureFlags to WebPFeatureFlags
- Elaborated a comment for a special case.
- A misc comment fix.

8d77dc29e1 Add support for lossless in mux:
- Separate out 'CHUNK_INDEX' from 'TAG_ID' (this is to help with the
  situation where two different tags - "VP8 " and "VP8L" can have the
  same TAG_ID -> IMAGE_ID).
- Some internal methods now take 'CHUNK_INDEX' param instea of 'TAG_ID'
  as appropriate.
- Add kChunks[] entry for lossless.
- Rename WebPMuxImage.vp8_ --> WebPMuxImage.img_
- SetImage() and AddFrame/Tile() infer whether the bitstream is a
  lossless one based on LOSSLESS_MAGIC_BYTE. The correct tag is stored
  based on this.

Also, handle the case when GetVP8Info/GetVP8LInfo() fails.

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.

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.
