Renamed mbits/mlimit to mleaf_bits/mleaf_limit

Browse Source 
- mbits -> mleaf_bits
- mlimit -> mleaf_limit
- mweight -> mleaf_weight
- lfsr_mridmask -> lfsr_midrmask
- lfsr_mbidmask -> lfsr_midbmask

This is a bit tricky to name, since we want to clarify it's not the
mtree limit and not the mdir's actual rbyd weight. But this also risks
confusing around the difference between mdirs/mleaves (mdirs are
mtree's leaves).
