martin 1ecf66db9f Make the pmap count resident/wired mappings on the fly instead of 
walking the page tables whenever this information is needed.

Add an option PMAP_COUNT_DEBUG to assert the new counts and the
page table walk agree.

The old solution had very bad performance impact, for example
by the high CPU load when running top(1).

Thanks to Simon Burge for pointing at the cause of the problem and
to Valeriy E. Ushakov for optimizing my simple minded assembler code.
