Th new function only needs to be called at initialization because bit
allocation parameters currently do not change during encoding.

cfff297d98 adpcm: Skip samples whose ssd calculation has wrapped around 
Wraparound in ssd is mainly avoided by subtracting the ssd of the
best node from all the others once it has grown large enough.

If using very large trellis sizes (e.g. -trellis 15), the frontier
is so large that the difference between the best and the worst is
large enough to cause wraparound, even if the ssd of the best one
is subtracted regularly.

When using -trellis 10 on a 30 second sample, this causes only a slight
slowdown, from 61 to 64 seconds.

38b3bda18f adpcm: Replace any of the leaf nodes in the heap 
By not looking for the exactly largest node, we avoid an O(n) seek through

An intermediate value in the floor 1 linear interpolation was
overflowing
resulting in obvious artifacts on some files.

e.g.
http://upload.wikimedia.org/wikipedia/commons/7/79/Big_Buck_Bunny_small.ogv

Prior to this fix 87 out of 128 64kbit/s mono files decoded with ffmpeg
have
lower PEAQ ODG values than the same files decoded with libvorbis. With
this
fix none of that set have significantly worse ODG values than libvorbis.
