Vitor Sessak 2b356efec2 Change the way the input is passed to do_hybrid_filter(). Before, in[0] was 
the oldest input sample passed and in[n-1] was the latest. Now it is the

Vitor Sessak 59da0390dc Remove st1 and st2 temporary buffers in backward_filter() and use instead 
RA288Context.pr{1,2}. Note that the pr{1,2} buffers are one unity smaller
than the st{1,2} buffers. My guess is that the original coder decided to
add one to the array sizes "just to be sure".
