checkunresolved: move to new package to help avoid import cycles

This will allow localrepo to stop using cmdutil, which should avoid
some future import cycles. There's room for an adventurous soul to
delve deeper into merge.py and figure out how to disentangle more of
it - it appears to be a nexus of cycle problems. Some of it might be
able to move into this new mergeutil package.
