Fix wrong IEEE 802.11 ioctl's:

* SIOCG80211ALLNODES operates on struct ieee80211_nodereq_all, not
struct ieee80211_nodereq.

* Six SIOC* from wi(4) were using same codes with generic parts of
IEEE 802.11 framework. Things worked due to the fact that size
of data struct being passed is encoded in actual SIOC*, too.

This commit means that ifconfig and some ports will need to be rebuilt,
if any of affected SIOC* codes is used. Port bumps to follow.

First part okay reyk@, whole diff okay mpi@
Heavy prodding to commit now from deraadt@

typos from Tom Cosgrove;

Tom: I did not commit a couple of your changes.

i did not include some punctuation fixes (full stops, etc.)
mnemorable -> mnemonic: i decided memorable was probably better
instrunctions -> instruction: i kept the plural

Use a 2-level timeout for hostap. Instead of of sending a station
a deauth/disassoc packet when the inactivity timer fires, just set
a flag, re-queue it and set the master wihap timer if needed. What
this does is to effectively bundle (and serialize) deauth/disassoc
packets so if a large number need to be sent at once we don't stomp
all over the card. We also only do at most 10 stations at a time.
The sta_list has been changed from a doubly linked list to a tailq.
Inactive stations are kept at the head of the queue, new ones are
added to the tail.

Also do a little KNF while I'm in here.

restore what was a default inactivity timeout, two minutes

kill lots of space and insert some more for knf

some BITS defs for %b

basic host-ap implementation, more work is needed; from Thomas Skibo <skibo@pacbell.net>; millert@ ok
