thin provisioned LUN support & file system allocation policy

One more consideration that I should have mentioned is that we can also
make our file system allocation policies "thin provisioned LUN" friendly.

Basically, we need to try to re-allocate blocks instead of letting the
allocations happily progress across the entire block range. This might
be the inverse of an SSD friendly allocation policy, but would seem to
be fairly trivial to implement :-)
