  Log:
  Add a new mechanism, cndbctl(), to tell the console driver that
  ddb is entered.  Don't refer to `in_Debugger' to see if we
  are in the debugger.  (The variable used to be static in Debugger()
  and wasn't updated if ddb is entered via traps and panic anyway.)
  
  - Don't refer to `in_Debugger'.
  - Add `db_active' to i386/i386/db_interface.d (as in
    alpha/alpha/db_interface.c).
  - Remove cnpollc() stub from ddb/db_input.c.
  - Add the dbctl function to syscons, pcvt, and sio. (The function for
    pcvt and sio is noop at the moment.)
  
  Jointly developed by: bde and me
  
  (The final version was tweaked by me and not reviewed by bde.  Thus,
  if there is any error in this commit, that is entirely of mine, not
  his.)
  
  Some changes were obtained from: NetBSD
