39e1b5cf8e use correct rounding functions
this should fix a floating point exception on some systems
lets hope these arent missing anywhere, if so another solution must be found

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)
