06e7fb82a4 remove duplicated parser, people who pass random gibblets of the bitstream into the decoder will have to pass it through a AVParser like for all other codecs too 
remove silly internal buffering architecture (removes 1 memcpy() of the bitstream)

5a7bd28335 move align_get_bits() to .h to avoid conflicts between different bitstream readers in different codecs 
add a skip_bits_long() which can skip by any amount in any direction (several codecs contain half working hacks to do that)
