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
contrary. This allows making backward_filter() somewhat simpler.

aed39f6c02 Remove RA288Context.output buffer. This buffer is just RA288Context.sb 
backwards (output[i] == sb[N-i], where N is the buffer length).

This makes the code slower, this will be fixed in my next commit.

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".
