f39706c2be Now that we can call vmpagesize without having a vm to hand, the implementation of vmcreate can be simpler: in particular, the grain size can already be correctly rounded up.

8c3e5886b4 Vmpagesize now takes no arguments -- this avoids suggesting (incorrectly) that it might return a different value for each vm. 
New function ProtGranularity returns the protection granularity of the operating system. (On all currently supported operating systems this is the same as the granularity of memory mapping returned by VMPageSuze, but it's important to separate these concepts.) MPMCheck asserts that the granularity of memory mapping is a multiple of the granularity of protection.
Client arena supports MPS_KEY_ARENA_GRAIN_SIZE.
Some of the test cases set the arena grain size.

5f84d4c3db Clarify tracefix logic by unwinding the nested conditions. 
Change the arena's chunk tree from a splay tree to an ordinary tree (so that it's not possible to accidentally splay it and leave it unbalanced).
New function TreeFindNext allows us to implement TractFirst and TractNext without having to splay the tree.
Make sure all operations on the chunk tree leave it balanced. But don't balance the tree directly in ChunkFinish() because this is only ever called in a loop where multiple chunks are being deleted from the tre. Instead use the sequence TreeToVine -- iterate and delete -- TreeBalance. The new macro TREE_DESTROY assists with this.
No need any more for ArenaIsReservedAddr, CHUNK_OF_ADDR, TRACT_OF_ADDR.
Update design documentation.

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.
