Re-add ifi_epoch, to struct if_data, this time replacing ifi_unused
to avoid ABI changes. It is set to the last time the interface
counters were zeroed, currently the time if_attach() was called. It is
intentended to be a valid value for RFC2233's ifCounterDiscontinuityTime
and to make it easier for applications to verify that the interface they
find at a given index is the one that was there last time they looked.
Due to space constraints ifi_epoch is a time_t rather then a struct
timeval. SNMP would prefer higher precision, but this unlikely to be
useful in practice.
