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.

f1abe0e30f Abolishing the redundant generation to zone map in the vm arena, and replacing it with chainalloc, which allocates segments within a generation. 
Generations from different chains will no longer share the same zone sets, and will not be collected together.  To get this behaviour, use the same chain, as documented.
