History
Bruce Evans 0477138dad 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, ... }.
