add an XentRestart, pointed to by the retore_term HWRPB vector (and maybe, 

eventually, the restart HWRPB vector), which calls console_restart.  This
is invoked when the console halt switch is used and the user enters 'c'
at the console prompt, and eventually causes a system crash dump to be
generated.
