Miles Bader implemented a new mmap based malloc which is much

smarter than the old "malloc-simple", and actually works, unlike
the old "malloc".  So kill the old "malloc-simple" and the old
"malloc" and replace them with Miles' new malloc implementation.
Update Config files to match.  Thanks Miles!
