[nemiver/varobjs-support] Add == operator for pointers to SafePtr

[Dodji Seketeli <dodji src gnome org>]

commit 2f183cecebb21fb555eae81f2c8464b1d2d6002f
Author: Dodji Seketeli <dodji redhat com>
Date:   Sat Apr 18 19:10:59 2009 +0200

    Add == operator for pointers to SafePtr
    
    	* src/common/nmv-safe-ptr.h: Add equality operator against
    	  pointers.
    	* src/dbgengine/nmv-i-debugger.h:
    	  (IDebugger::Variable::build_qname): Adjust. Don't use equality
    	operator to test pointer nullity, rather use the bool () operator.
