kernel - Partition large anon mappings, optimize vm_map_entry_reserve*()

* Partition large anonymous mappings in (for now) 16MB chunks.
  The purpose of this is to improve concurrent VM faults for
  threaded programs.  Note that the pmap itself is still a
  bottleneck.

* Refactor vm_map_entry_reserve() and related code to remove
  unnecessary critical sections.
