Add simple malloc statistics and metrics

Browse Source 
Add some basic statistics for allocated memory based on mallinfo(),
and use that to define two metrics:

 usedAfterOverview: bytes used after the overview is shown once
 leakedAfterOverview: additional bytes used when the overview is
   shown a second time.
