8fbb91884e prefer webp/types.h over stdint.h 
stdint.h is part of C99 and is notably lacking under MSVC

c6882c49e3 merge all tree processing into a single VP8LProcessTree() 
-> 0.1% size improvement because we're calling OptimizeForRLE()
systematically now.

9f566d1d36 clean-up around Huffman-encode 
* refine doc
* use LUT for bit-reversal
* added assert
* Introduce HuffmanTreeToken instead of separate code/extra_bits arrays

2c140e113c Some cleanup in VP8LCreateHuffmanTree() (and related functions 
CompareHuffmanTrees() and SetBitDepths()):
- Move 'tree_size' initialization and malloc for 'tree + tree_pool'
  outside the loop.
- Some renames/tweaks for readability.

352a4f49ab Get rid of PackLiteralBitLengths() 
[and in turn a malloc]. Also, a few related const fixes.
