--------------------------------+-----------------------------------------
 A lot of DHCP test code relies on allocating objects on the heap and
 storing the address in a raw pointer, then using delete at the end of the
 test to destroy it. Occasionally the delete is missed and the valgrind
 pass fails.

 Unless there is a compelling reason otherwise, objects allocated during
 tests should be pointed to by a smart pointer.  This ticket is for a
 refactoring of the existing tests to do this.
