UserspaceEmulator: Implement very basic leak checking :^)

Upon exit, the emulator will now print a leak report of any malloc
allocations that are still live and don't have pointers to their base
address anywhere in either another live mallocation, or in one of the
non-malloc-block memory regions.

Note that the malloc-block memory region check is not fully functional
and this will work even better once we get that fixed.

This is pretty cool. :^)
