Makes tracking allocator default to crashing on a bad free instead of add to bad_free_array. The bad_free_array remains to not break old code. The new default behavior is implemented in a callback that you can override, there's a second provided callback that provides the old behavior where an element was added to bad_free_array. Rationale: Many people are just checking the allocation_map, but don't check the bad free array. Several examples throughout core that use tracking allocator don't check bad_free_array either, so people have been taught not to check it.
