Alfred Perlstein 79f62ed690 Allow maxusers to scale on machines with large address space.
Some hooks are added to clamp down maxusers and nmbclusters for
small address space systems.

VM_MAX_AUTOTUNE_MAXUSERS - the max maxusers that will be autotuned based on
physical memory.
VM_MAX_AUTOTUNE_NMBCLUSTERS - max nmbclusters based on physical memory.

These are set to the old values on i386 to preserve the clamping that was
being done to all arches.

Another macro VM_AUTOTUNE_NMBCLUSTERS is provided to allow an override
for the calculation on a MD basis.  Currently no arch defines this.
