* Add dlmalloc_strat allocator strategy
- Use mspace variant to ease encapsulation
- Make pow2bins and dlmalloc cmake selectable
* Add unit tester for dlmalloc, rework single_heap, pow2bins unit testers
accordingly
- add dlmalloc get_used/get_avail, and have all strats allocators also have a get_used
- Rework memallocator unit tests: bin size is per strat, alignment is verified in singleheap
* bugfix: dlmalloc exposed that the pingpong test would write past end of
allocation with -w 32
* iostream leakage/mixed usage of cerr and fprintf(stderr
