In sysctl(8), you can set an integer type, but the max value
an int can be is 2 * N-1 where N is the size of int. This leads
to a problem when trying to set kern.hostid and the number is
greater that 2GB on an IA32 system. So my question is should
CTLTYPE_INT be treated as a long or some other larger numeric
number? Or should we declare some CLTYPE_UINT type?
If there is going to be overflow, should it not be because
of the sysctl being set and not because of the sysctl(8) causing
it?
See PR kern/21132 for an instance.
