- 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.

- 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.

group like parameters together in prototypes, comments, move variable
declarations closer to first use.

- const / move declarations closer to first use
- remove unnecessary ()s
- don't return int unnecessarily with internal Init/Release
- compact some lines

- remove some unused functions
- move global arrays from data to read only section
- explicitly cast malloc returns; not specifically necessary, but helps
show intent
- miscellaneous formatting

Make sure chunk->data and wpi are not leaked by
MuxAddFrameTileInternal() in case of MEMORY_ERROR in ChunkSetNth().

Add extern to kChunks[] in muxi.h.
Fixes:
ld: duplicate symbol _kChunks in .libs/muxinternal.o and .libs/muxedit.o

alpha information is not to be found at RIFF chunks level, not
in the VP8 bitstream (that was a tmp hack)

- 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.

This change adds the WebP Mux library for manipulating the WebP Mux
Container. The library document and command line tool exhibiting the
usage of this libary will follow in subsequent Git change.
