9dc8bd1e70 Because of the requirement to make popped objects dead in a timely fashion, we can only implement lightweight pops to an address in the buffer. in particular we can't support pending pops, which means that there's no need for the fields in the allocation point that support pending pops.

53c5301a9e Instead of iterating over the chunks to compute the total reserved address space, maintain a running total in arenachunkinsert and (new function) arenachunkremoved.

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.
