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

webp: add a special case for a huffman table with only 1 symbol

webp: do not call av_frame_free() on the user-provided frame

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.

Fixes double-free on error.

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