Hi

The patches below add a 2pass mode to ffv1 that optimally sorts the range
coder states. The compression gain is for my test quite small but more things
can be added in the future to be finetuned in 2 passes ...
Also ive not been able to meassure speedloss here for the added code.

Ill apply this patchset soon as it seems quite trivial.
