synchronization protecting against dynamic load and unload of MAC
policies, and instead simply blocks load and unload. In a static
configuration, this allows you to avoid the synchronization costs
associated with introducing dynamicism.

This little thing can cause a deadlock, because taste mechanism start
to work after creation of ggate provider and I/O requests are sent from
other classes from the g_event thread, so number of pending events isn't 0.
Now ggatec(8) start second handshake and ggated(8) is trying to open
GEOM provider (for example md(4)) and it can't, because it hangs on
g_waitidle() in g_dev_open(). g_waitidle() cannot finish because
there is a pending read on event queue, and this read can't be
finished, because ggated(8) can't open target device.
GEOM Gate will recover from this deadlock, because requests will
timeout, but it of course isn't the best solution and I don't know
better one for now, so we should avoid opening GEOM providers while
there are pending requests in event queue.

- Only do an outb() to the PIC to clear a bit in imen if the bit is set.
- Add a NUM_ISA_IRQS macro to replace uglier
'sizeof(array) / sizeof(member)' expressions along with a CTASSERT() to
ensure that the macro is correct.
than using legacy_pcib_attach(). The MP Table drivers don't use the $PIR,
and the legacy_pcib_attach() function probes and parses the $PIR in
addition to adding the pci bus child device.
o New function ip_findroute() to reduce code duplication for the
route lookup cases. (luigi)
o Store ip_len in host byte order on the stack instead of using
it via indirection from the mbuf. This allows to defer the host
byte conversion to a later point and makes a quicker fallback to
normal ip_input() processing. (luigi)
o Check if route is dampned with RTF_REJECT flag and drop packet
already here when ARP is unable to resolve destination address.
An ICMP unreachable is sent to inform the sender.
o Check if interface output queue is full and drop packet already
here. No ICMP notification is sent because signalling source quench
is depreciated.
o Check if media_state is down (used for ethernet type interfaces)
and drop the packet already here. An ICMP unreachable is sent to
inform the sender.
o Do not account sent packets to the interface address counters. They
are only for packets with that 'ia' as source address.
o Update and clarify some comments.

o Extend the if_data structure with an ifi_link_state field and
provide the corresponding defines for the valid states.
o The mii_linkchg() callback updates the ifi_link_state field
and calls rt_ifmsg() to notify listeners on the routing socket
in addition to the kqueue KNOTE.
o If vlans are configured on a physical interface notify and update
all vlan pseudo devices as well with the vlan_link_state() callback.

This is in preparation for media state change notification to the
routing socket.

o Fix and improve comments and references,
o Add PFIL_HOOKS, UFS_ACL and UFS_DIRHASH,
o Switch from SCHED_4BSD to SCHED_ULE,
o Remove SCSI_DELAY (there's no SCSI support),
One thing Gzip does is implicitly by store the size of a file into an
'unsigned long' rather than explicitly compute the remainder modulo 2^32
(see RFC 1952 section 2.3.1 "ISIZE"). Thus an extracted file size is
does not equal the original size (mod 2^32) for files larger than 4GB.
This manifests itself in errors such as:

- change pf_get_pool() argument rule_number type from u_int32_t
to u_int8_t, fixes corruption of address pools with large
rulesets (mcbride@)
- prevent endless loops with route-to (dhartmei@)
- limit option length to 2 octets max (frantzen@)
