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)

add a skip_bits_long() which can skip by any amount in any direction (several codecs contain half working hacks to do that)
