> Add bloomfiltering to hfile.  Can be enabled on a family-level basis.  Ability to configure
a row vs row+col level bloom.  We size the bloomfilter with the number of entries we are about
to flush which seems like usually we'd be making a filter too big, so our implementation needs
to take that into account.
