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.

Abstracting partially mapped page tables into a sparsearray abstract datatype, removing a great deal of complexity from the vm arena, and some unnecessary double-initialisation and scanning loops during allocation.
