Use a better malloc for the core. In particular, use the same core
that we should eventually be able to use for the entire system in

This code can also accommodate multiple heaps. Set up a separate heap
for lowmem; the intent is to use explicit lowmem allocations instead
of the static bounce buffer. The lowmem allocation is also exported
via the pmapi mechanism, so modules can safely allocate lowmem.
