core: use better malloc; add low memory malloc; fix com32 exit
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
Syslinux 5 -- with module awareness, etc.
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.
