Ronald S. Bultje	4ffe5e2aa5	huffyuv: add padding to classic (v1) huffman tables. We slightly overread the input buffer, so we require padding at the end of the buffer, as is documented in the get_bits API. Without padding, we'll read uninitialized data or beyond the end of the .rodata, which may crash. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
