c6698dfe7c webpdec: Fix decoding of the huffman group indices. 
Per the specification, "The red and green components of a pixel
define the meta Huffman code used in a particular block of the ARGB
image."

Also remove "webp:" from log messages. Using the AVCodecContext is enough.

d085f80fa1 webp: add a special case for a huffman table with only 1 symbol 
The vlc reader cannot handle 0-bit huffman codes. For most
situations WebP uses the "simple" huffman coding for this case,
but that will only handle symbols up to 255. For the LZ77 distance
codes, larger symbol values are needed, so it can happen in rare
cases that a normal huffman table is used that only has a single
symbol.

The previously existing webp decoder is disabled as the new
one supports lossless mode and alpha while the previous does not.
