This change was agreed in 1997 (see <https://info.ravenbrook.com/project/mps/mail/1997/08/19/13-44/0.txt>), so it's about time it was implemented.

87b3880405 New generic function landsize returns the total size of ranges in a land (if the land supports it). implement it for all land classes. 
The MVFF pool class doesn't have to maintain its free size any more: it can just call LandSize.
Move re-entrancy protection from CBS to Land. This allows us to remove some CBS functions. (But requires some adjustment in failoverDelete.)
In MVFF, do more checking of mvff->total.
