Add native memory accounting through custom allocator.
Added a custom allocator that lets you pass in a special tag which
specifices where the allocation came from. This is used when
dumping. The performance overhead is low since each allocation only
does a atomic add/sub for each allocation/free.
The measurements are dumped to traces.txt during SIGQUIT.
