device_get_softc() provides the right info even if it's overkill.

The big lines are:
NODEV -> NULL
NOUDEV -> NODEV
udev_t -> dev_t
udev2dev() -> findcdev()
Various minor adjustments including handling of userland access to kernel
space struct cdev etc.
- prevent an endless loop with route-to lo0, fixes PR 3736 (dhartmei@)
- The rule_number parameter for pf_get_pool() needs to be 32 bits, not 8 -
this fixes corruption of the address pools with large rulesets.

timeout values in the CAM CCBs. Divide by 1000 to get values in seconds
which are what ata(4) timeouts internally use.
This does lose granularity, though, and small values can now round down
to zero. It's probably worth making all ata(4) timeouts in terms of
hz/ticks/milliseconds/something.
Version 3.5 brings:
- Atomic commits of ruleset changes (reduce the chance of ending up in an
inconsistent state).
- A 30% reduction in the size of state table entries.
- Source-tracking (limit number of clients and states per client).
- Sticky-address (the flexibility of round-robin with the benefits of
source-hash).
- Significant improvements to interface handling.
- and many more ...
- Remove pflog and pfsync modules. Things will change in such a fashion
that there will be one module with pf+pflog that can be loaded into
GENERIC without problems (which is what most people want). pfsync is no
longer possible as a module.
- Add multicast address for in-kernel multicast pfsync protocol. Protocol
glue will follow once the import is done.
- Add one more mbuf tag

an unsigned value. It is well defined and intended, but since signess bugs

o Mask the lower 8 bits, not the lower 4 bits for the ai_capabilities word.
All 8 bits are defined and the 0xf was almost certainly a typo.
o Define APM_UNKNOWN to 0xff for emulation layer.

fixes the problem of UDP sockets getting wedged in a connected state (and
bound to their destination) under heavy load.
Temporary bind/connect should probably be deleted in future
as an optimization, as described in "A Faster UDP" [Partridge/Pink 1993].
Notes:
- INP_LOCK() is already held in udp_output(). The connection is in effect
happening at a layer lower than the socket layer, therefore in theory
socket locking should not be needed.
- Inlining the in_pcbdisconnect() operation buys us nothing (in the case
of the current state of the code), as laddr is not part of the
inpcb hash or the udbinfo hash. Therefore there should be no need
to rehash after restoring laddr in the error case (this was a
concern of the original author of the patch).

using rawcb_mtx. Hold this mutex while modifying or iterating over
the control list; this means that the mutex is held over calls into
socket delivery code, which no longer causes a lock order reversal as
the routing socket code uses a netisr to avoid recursing socket ->
routing -> socket.
Note: Locking of IPsec consumers of rawcb_list is not included in this
commit.
