c968255f1e Ensure that code of the form if (condition) statement; is split over two lines, so that it is possible to set a breakpoint on the statement in a debugger. 
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.

1f517274f3 Cast all arguments to the writef function to make it easy to check that none of the necessary casts have been omitted. 
New macro WriteFYesNo makes it easy to describe a Boolean.
Describe more structure elements for ABQ, Arena, Buffer, Format, MFS, Root, Seg.

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.

0b159dc650 New module failover implements a fail-over allocator as a land class.

Test Failover in landtest.
Implementation of LandFindInZones for Freelist (untested).
