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.

24abd806ea ljpegenc: deMpegEncContextize 
The encoder uses almost none of the mpegvideo infrastructure, only some
fields from MpegEncContext.

The FATE results change because now an all-zero quant matrix is written
into the file. Since it is not used for anything for ljpeg, this should
not be a problem.

66499f34b5 mpegvideo: do not set current_picture_ptr in decoders 
This code was originally added in
5f1948111a to h263 to set decoded frame
pts to some random numbers (removed in
a1c5cc429d) and then cargo culted to other
decoders.

The code is left in h263dec for now, since some part of the decoder
(apparently OBMC) relies on the specific previous frame to be reused.

3d7c84747d x86: Initialize mmxext after amd3dnow optimizations

amd3dnow optimizations are being deprecated. Thus the former should

01f6df01b6 go2meeting: disallow tile dimensions that are not multiple of 16 
Original decoder seems to always use 176x128 tiles anyway and this helps
avoiding lots of issues with odd tile sizes in fuzzed files.
