b74ed6e766 Mux API change: 
'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.

04e33f17de Edit for consistency, usage and grammar. 
Substantial edit, though less than 100% thorough.  This
makes changes that are clearly safe, but avoids others
where my domain knowledge is incomplete and accuracy
might be compromised.

8a69c7d8af Bug-fix: Clamp backward dist to 1. 
Check for valid bounds on the 'dist' in backward reference case.
Clamp it to 1 in case of zero and negative values.

b3923084b9 Limit the maximum size of huffman Image to 16MB. 
This limit corresponds to default histo_bits=3 for images upto sizes 400x400.
Any image higher than this dimension will bump up the histo_bits to 4 internally.
