import-trace: add --cover-memorymap switch

Browse Source 
This compatibility-breaking change introduces the --cover-memorymap
switch to import-trace.  It makes a previous behavior optional, which
enforces DB entries for addresses covered by the --memorymap that
don't occur in the trace.  This creates a continuous and potentially
very large fault space in the DB, which never made any real sense.
