Changed code from using cl_UP_MI to using umodpoly. The cl_UP_MI interface was
inconvenient to use and caused several very difficult bugs (some were still
unresolved before changing to umodpoly!).

Fixed severe bug in multivariate factorization. The condition that all modular
factors should be relatively prime in the base ring was violated. This caused
the factorization sometimes to go into an infinite loop.
