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.

1d9afa915f Fix arenadescribetracts: 
* Return value from TreeVisitor is Bool, not Res, so pass Res back via a closure.
* Can't use TRACT_TRACT_FOR while iterating over the chunk tree, because that macro uses ChunkOfAddr. (A plain loop is simpler.)
* Mustn't try to describe unallocated tracts -- they might not even be mapped into memory. So consult the allocTable.
Make tract functions more robust:
* TractCheck must only check the pool if there is one (otherwise it segfaults for unallocated tracts)
* TractLimit can't look up the arena via TractPool, because the tract might not have a pool. So pass in the arena as an argument.
