  Modified files:
    sys/kern             subr_bus.c 
  Log:
  Fixed allocation of unit numbers.  Allocate the amount of space actually
  required (rounded up a little) instead of twice the previous amount (or
  a fixed amount for the first allocation).
  
  The bug caused memory corruption when a new unit number for a devclass
  was more than about twice the previous maximum one (or more than 3 for
  the first one), so it corrupted memory (which happened to be the atkbdc
  port resource list) in the reporter's configuration with sio unit
  numbers { 0, 25, 1, 2, ... }.
