  Log:
  Add the mlockall() and munlockall() system calls.
   - All those diffs to syscalls.master for each architecture *are*
     necessary. This needed clarification; the stub code generation for
     mlockall() was disabled, which would prevent applications from
     linking to this API (suggested by mux)
   - Giant has been quoshed. It is no longer held by the code, as
     the required locking has been pushed down within vm_map.c.
   - Callers must specify VM_MAP_WIRE_HOLESOK or VM_MAP_WIRE_NOHOLES
     to express their intention explicitly.
   - Inspected at the vmstat, top and vm pager sysctl stats level.
     Paging-in activity is occurring correctly, using a test harness.
   - The RES size for a process may appear to be greater than its SIZE.
     This is believed to be due to mappings of the same shared library
     page being wired twice. Further exploration is needed.
   - Believed to back out of allocations and locks correctly
     (tested with WITNESS, MUTEX_PROFILING, INVARIANTS and DIAGNOSTIC).
