Allow targets to exceed floor, add another check

Sometimes we want to transfer a shard to a target even though it's
already at the floor.  We add another check to make sure we're not
wasitng effort -- the difference in shard counts between the source and
the target must be 2 or greater.

We also refactor the global shard count code to avoid future atom /
binary problems.
