fixup inactivity timers:
o ic_inact_auth is a bad name, it's the inactivity threshold
for being associated but not authorized; use it that way
o reset ni_inact when switching inactivity thresholds to
minimize the race against the timer (don't want to lock
for this stuff)
o change the inactivity probe threshold from a one-shot to
cover a range: when below this threshold but not expired
send a probe each inactivity interval; should probably
guard against the interval being turned way down as this
could cause us to spam the net with probes

Link ALTQ to the build and break with ABI for struct ifnet. Please recompile
your (network) modules as well as any userland that might make sense of
sizeof(struct ifnet).
This does not change the queueing yet. These changes will follow in a
seperate commit. Same with the driver changes, which need case by case
evaluation.

__FreeBSD_version bump will follow.

Change handling of probe response frames. Previously we always dropped the
refcnt on the node but left it in the node table. This allows the node table
to hold the results of scanned ap's but for ibss scans left nodes w/o any
driver-private state setup and/or a bad refcnt (when the nodes were timed
out they were prematurely discarded). Now we treat nodes identified for ap
scanning as before but force nodes discovered when scanning for ibss neighbors
to have complete/proper state and hold the refcnt on the node. Any other
nodes created because of these frames are discarded directly (need to optimize
this case to eliminate various work that's immediately discarded).

always free node reference when processing a probe request frame; was
conditionally doing an unref if operating in adhoc mode which turns
out to be wrong

when processing beacon/probe response frames capture "is probe" in a

add a case of IEEE80211_ELEMID_IBSSPARMS so the statistic on unknown
elements is more meaningful (will add more with WPA merge)

Obtained from: madwifi

when doing internal bridging free the node instead of just dropping the
reference for consistency (explicit refcounting is discouraged)

when receiving a frame w/ a bad version number don't unref the node; the
driver is responsible for that

Add support for FH phy, which will be used by awi driver.
Also some if_media constants to indicate operational mode are changed
to bitmasks to reduce diffs from NetBSD.

fix station mode breakage (repeat after me: "test every change, no
matter how small...")

add statistics for all failures and/or abnormal events; still need
to add per-node statistics

In particular, let drivers send up control frames so we can dispatch

MFp4 changes to fix locking issues and correct reference
count handling of station entries in hostap mode:

Input path:

o driver is now expected to find the node associated with the
sender of a received frame; use ic_bss if none is located
o driver passes the (referenced) node into ieee80211_input for
use within the wlan module and is responsible for cleaning up
on return
o the antenna state is no longer passed up with each frame; this
is now considered driver-private state and drivers are responsible
for keeping it in the driver-private part of a node

Output path:

Revamp output path for management frames to eliminate redundant
locking that causes problems and to correct reference counting
bogosity that occurs when stations are timed out due to inactivity
(in AP mode). On output the refcnt'd node is stashed in the pkthdr's
recvif field (yech) and retrieved by the driver. This eliminates
an unref/ref scenario and related node table unlock/lock due to the
driver looking up the node. This is particularly important when
stations are timed out as this causes a lock order reversal that
can result in a deadlock. As a byproduct we also reduce the overhead
for sending management frames (minimal). Additional fallout from
this is a change to ieee80211_encap to return a refcn't node for
tieing to the outbound frame. Node refcnts are not reclaimed until
after a frame is completely processed (e.g. in the tx interrupt
handler). This is especially important for timed out stations as
this deref will be the final one causing the node entry to be
reclaimed.

Additional semi-related changes:
o replace m_copym use with m_copypacket (optimization)
o add assert to verify ic_bss is never free'd during normal operation
o add comments explaining calling conventions by drivers for frames
going in each direction
o remove extraneous code that "cannot be executed" (e.g. because
pointers may never be null)
