Refactor the malloc_info code.

malloc_info needs to be per native allocator, but the code treated it
like a global function that doesn't depend on the native memory allocator.

Update malloc debug to dump the actual pointers that it has been tracking.

Test: bionic-unit-tests pass.
Test: malloc debug tests pass.
Test: malloc hook tests pass.
