receiving interface in the packet header of every mbuf.
The interface pointer should now be retrieved when necessary with
if_get(). If a NULL pointer is returned by if_get(), the interface
has probably been destroy/removed and the mbuf should be freed.
Such mechanism will simplify garbage collection of mbufs and limit
problems with dangling ifp pointers.
Tested by jmatthew@ and krw@, discussed with many.

Each physical interface of a trunk now gets a specific ifih (interface
input handler) that runs before ether_input().

This removes the system wide if_slowtimo timeout and lets every
interface with a valid if_watchdog method register it's own in
order to get rid of the ifnet loop in the softclock context and
avoid further complications with concurrent access to the ifnet
list.

the various bpf_mtap_* are very similiar, they differ in what (and to some
extent how) they prepend something, and what copy function they pass to
bpf_catchpacket.
use an internal _bpf_mtap as "backend" for bpf_mtap and friends.
extend bpf_mtap_hdr so that it covers all common cases:
if dlen is 0, nothing gets prepended.
copy function can be given, if NULL the default bpf_mcopy is used.
adjust the existing bpf_mtap_hdr users to pass a NULL ptr for the copy fn.
re-implement bpf_mtap_af as simple wrapper for bpf_mtap_hdr.
re-implement bpf_mtap_ether using bpf_map_hdr
re-implement bpf_mtap_pflog as trivial bpf_mtap_hdr wrapper

the mbuf it just sent on the previous interface. this is bad because the
previous interface could have modified the mbuf chain, which can make the
subsequent m_copym()s panic.
this copies the dance that rtsock.c does for broadcasting mbufs which
copies the mbuf before transmit, except for the last interface which it
handles outside the loop.
tested by halex@ who verified it fixes his panic.

to the new MAC. But subsequently added ports were still being assigned the
old MAC address because it was copied from the wrong place. Give newly added
trunk ports the current MAC of the master port, rather than the saved MAC of
the master port. The saved MAC should only be used to restore the original
MAC address of the interface when it is removed from the trunk.

sysctl.h was reliant on this particular include, and many drivers included
sysctl.h unnecessarily. remove sysctl.h or add proc.h as needed.

this prevents the ultimate length of the queue of the underlying interface
from being artificially inflated while hte vlan/trunk queue is filled and
then dumped wholesale on the underlying interface, which will dump its
massive queue wholesale on the chip.
tx mitigation is only triggered on real interfaces now (which is where the
cost is)

interfaces down to the queue on the physical interface immediately.
this avoids having the tx mitigation code wasting cpu time dicking around
with simply shuffling packets off virtual interface queues and lets it
do its job of ammortising the cost of calling a real interfaces start
routine.
it also prevents an artificial inflation of the physical interfaces queue
length where packets could hide on the virtual interfaces queues during
softnet before being dumped en masse onto the hardware. this will smooth
out the rate at which packets are submitted to the hardware.
