Remove any stale mbuf tags from packets being injected into a netgraph
graph. In particular, this solves some issues with (probably leaked)
IPSec-related tags being looped back through netgraph to the inbound
path which then misinterpreted the stale tags.

Provide fake link status information in an attempt to let ng_eiface(4)
virtual ifnets more realistically mimic physical ethernet interfaces.
The main motivation behind this change is to allow for ng_eiface(4)
interfaces to participate in STP if_bridge(4) configurations.

When announcing link status changes, switch to the vnet to which the
ifnet belongs, since it is possible for ng_eiface ifnets to be assigned
to a vnet different from the one in which its netgraph node resides.

After some off-list discussion, revert a number of changes to the
DPCPU_DEFINE and VNET_DEFINE macros, as these cause problems for various
people working on the affected files. A better long-term solution is
still being considered. This reversal may give some modules empty
set_pcpu or set_vnet sections, but these are harmless.

__stop_set_xxx symbols, only emit them when the set_vnet or set_pcpu

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.
