a94cc2ed78 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.

3d1db4eab6 Use cbs subclasses to implement the fast-find and find-in-zones features. this avoids the need to control behaviour by passing booleans, and it means that there is no wasted space in the cbs block structure when these features are not used.
Bring splay tree design up to date; add missing diagrams; move it to the "current" section of the manual.

bcea6812fc Improve control over checking:
1. Where Type is a pointer type with a signature, replace CHECKL(TypeCheck(val)) with CHECKD(Type, val).
2. Where Type is a pointer type with no signature, replace CHECKL(TypeCheck(val)) with CHECKD_NOSIG(Type, val).
3. Where Type is a pointer type with a signature, but the structure is not visible at point of checking, replace CHECKL(TypeCheck(val)) with CHECKD_NOSIG(Type, val). Reference <design/check/#.hidden-type>
4. Make BTCheck extern and use it where possible.
5. Replace AVER(TypeCheck(val)) with AVERT(Type, val).

67ab8d1385 New test case "fotest" for fail-over of cbs to freelist in mvff. (plus stub for mvt.) need some testing hooks in mvff and mvt for getting the cbs.
This reveals a couple of bugs in MVFF: (i) if CBSDelete fails, this might be because the block is actually on the Freelist instead; (ii) we can't SegFree before calling FreelistDelete because the Freelist needs access to the memory in order to read its pointers.

* MVFF shouldn't assume that CBSInsert and CBSDelete can't fail.
* Remove unused function mps_mvff_stat.
* Don't call range methods in RangeCheck.
* RangeInit can't fail, so return void.
