- WEBP_MUX_INVALID_PARAMETER: was used only at one place, and that too
should actually be an assert().
- WEBP_MUX_ERROR: was never used.

minor revision shouldn't matter, we only check major revision number.
Bumped all version numbers so that incompatibility starts *now*

- 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.

The image_info_ was used only in GetImageCanvasWidthHeight(). So, now
we infer it from data there.
This removal fixes a bug: earlier, 'image_info' wasn't initialized in
the WebPMuxCreate() flow, and so the canvas width/height were being
calculated to be zero.
Also, a related refactoring: Combine CreateImageInfo() and
CreateDataFromImageInfo() into a single function CreateFrameTileData().
Change-Id: I7b0afb0d36dc6e13b9d6a1135fb027aa4e03716c
'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.

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]

- 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().
