int rpmpsTrim rpmps    ps,
rpmps    filter
 

Filter a problem set.

As the problem sets are generated in an order solely dependent on the ordering of the packages in the transaction, and that ordering can't be changed, the problem sets must be parallel to one another. Additionally, the filter set must be a subset of the target set, given the operations available on transaction set. This is good, as it lets us perform this trim in linear time, rather then logarithmic or quadratic.

Parameters:
ps  problem set
filter  problem filter (or NULL)
Returns:
0 no problems, 1 if problems remain
