098b4da32d New function mps_arena_configure provides keyword argument interface to changing the properties of an arena. 
New keyword arguments MPS_KEY_ARENA_COMMIT_LIMIT and MPS_KEY_SPARE_ARENA_COMMIT_LIMIT can be passed to mps_arena_create_k or mps_arena_configure.
Deprecate mps_arena_commit_limit_set and mps_arena_spare_commit_limit_set.

9436487a05 Instead of iterating over the chunks to compute the total reserved address space, maintain a running total in arenachunkinsert and (new function) arenachunkremoved. 
New arena class method chunkReserved handles the class-specific computation of the reserved size of a chunk.

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.
