05ac242c57 If you try to create a client arena that's too small for the full complement of zones, return mps_res_memory instead of asserting. 
If you try to create a virtual memory arena that's too small for the full complement of zones, round up the size to the minimum instead of asserting.

Account for (and check) committed memory in the client arena class.
Can't check arena->committed <= arena->reserved in ArenaCheck, but can in ClientArenaCheck.

53c5301a9e 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.

83a93881a2 Design.mps.ring.naming: "when one structure parent contains one ring of child structures, the field in parent is usually known as childring, and the field in child is known as parentring". so the field in chunkstruct should be named arenaring.

831f551eec 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.

88c85abc0e 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.

2f0ef9355d 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.

d3d2795fce Improve control over checking:

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).
