Add a new variable, ifi_epoch, to struct if_data. It is set to the last

time the interface counters were zeroed, currently the time if_attach()
was called.  It is indentended 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.

An if_epoch "compatability" macro has not been created as ifi_epoch has
never been a member of struct ifnet.
