When working on memory, it's nice to be able to test your work.
Add a memtest module. When compiled with --enable-mm-debug, it exposes
3 commands:
* lsmem - print all allocations and free space in all regions
* lsfreemem - print free space in all regions
* stress_big_allocs - stress test large allocations:
- how much memory can we allocate in one chunk?
- how many 1MB chunks can we allocate?
- check that gap-filling works with a 1MB aligned 900kB alloc + a
100kB alloc.
