MFC r202588

Declare a new EVENTHANDLER called iflladdr_event which signals that the L2
address on an interface has changed. This lets stacked interfaces such as
vlan(4) detect that their lower interface has changed and adjust things in
order to keep working. Previously this situation broke at least vlan(4) and
lagg(4) configurations.

The EVENTHANDLER_INVOKE call was not placed within if_setlladdr() due to the
risk of a loop.

Ignore failures from removing multicast addresses from the parent (trunk)
interface when tearing down a vlan interface. If a trunk interface is
detached, all of its multicast addresses are removed before the ifnet
departure eventhandlers are invoked. This means that all of the multicast
addresses are removed before the vlan interfaces are removed which causes
the if_delmulti() calls in the vlan teardown to fail.

In the VLAN_ARRAY case, this left vlan interfaces referencing a no longer
valid parent interface. In the !VLAN_ARRAY case, the eventhandler gets
stuck in an infinite loop retrying vlan_unconfig_locked() forever. In
general the callers of vlan_unconfig_locked() do not expect nor handle
failure, so I believe it is safer to ignore the errors and tear down as
much of the vlan state as possible.
