* 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 --------- Signed-off-by: Aurelien Bouteiller <aurelien.bouteiller@amd.com>
