Modified Files:
        src/sys/ddb: db_command.c
        src/sys/kern: kern_history.c
        src/sys/sys: kernhist.h

Log Message:
Improve ddb(4) show kernhist

1) really prints all the histories merged together (rather than just the
   "first" when no argument specified
2) dumps a single history when an argument is given, e.g.
   "show kernhist usbhist"
3) uses db_printf correctly
