MFC the change of ifi_epoch to be uptime instead of wall clock time.
The origional commit message follows:

	Change the definition of struct if_data's member ifi_epoch from
	wall clock time to uptime because wall clock time may go
	backwards.

	This is a change in the API which will impact SNMP agents who
	are using ifi_epoch to set RFC2233's ifCounterDiscontinuityTime.
	None are known to exist today.  This will not impact applications
	that are using the <index, epoch> tuple to verify interface
	uniqueness except that it eliminates a race which could lead to
	a false assumption of uniqueness.
