'Set' and 'Get' methods for images take/return a bitstream as input,
instead of separate 'image' and 'alpha' arguments.
Also,
- Make WebPDataCopy() a public API
- Use WebPData for storing data in WebPChunk.
- Fix a potential memleak.

- 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.

- 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.
Change-Id: Idd6bd87d0366d783fed83f4dd21bd7968cbe6948
- const / move declarations closer to first use
- remove unnecessary ()s
- don't return int unnecessarily with internal Init/Release
- compact some lines
Change-Id: If7ab505e417221debc356f21f075506939110a84
- 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().
