 The pack() methods of Pkt4 and Pkt6 currently return a bool value, with
 false indicating a failure.  A failure can also be signalled by an
 exception being thrown.  This ticket removes the inconsistency:  the
 functions should be declared {{{void}}} and packing errors indicated by
 the throwing of an exception.  The code where they are used (in the
 DHCP4/6 server) must be modified to handle the change.
