Move the code in fill_kinfo_thread() that gathers data from struct proc
into the new function fill_kinfo_proc_only().
Change all callers of fill_kinfo_thread() to call both
fill_kinfo_proc_only() and fill_kinfo() thread. When gathering
data from a multi-threaded process, fill_kinfo_proc_only() only needs
to be called once.
Grab sched_lock before accessing the process thread list or calling
fill_kinfo_thread().

- Make it so one can't call db_setup_paging() if it has already been called
before. traceall needs this, or else the db_setup_paging() call from
db_trace_thread() will reset the printed line number, and override its
argument.
This is not perfect for traceall, because even if one presses 'q' while in
the middle of printing a backtrace it will finish printing the backtrace
before exiting, as db_trace_thread() won't be notified it should stop, but
it is hard to do better without reworking the pager interface a lot more.

(pf used to start late during system boot, after
many a network daemon have started already, which
sucked from security POV.)
Remark: For maximum security, pf should start before
netif, but it would create a dependency loop because
pfsync has to start after netif, yet before pf.

system boot, and hook it up in the system.
The separate script is needed because in the presence of various
interface lists in rc.conf ($network_interfaces, $cloned_interfaces,
$sppp_interfaces, $gif_interfaces, more to come) it is hard to start
them orderly, so that pfsync is brought up after its syncdev, which
is required for the proper startup of pfsync.

- WEP TX fix:
The original code called software crypto, ieee80211_crypto_encap(),
which never worked since IEEE80211_KEY_SWCRYPT was never flagged due to
ieee80211_crypto_newkey() assumes that wi always supports hardware based
crypto regardless of operational mode(by virtue of IEEE80211_C_WEP).
This fix works around that issue by adding wi_key_alloc() to force
the use of s/w crypto. Also if anyone ever decides to cleanup ioctl
handling where key changes wouldn't cause a call to wi_init() every time,
we'll need wi_key_alloc() to DTRT.
In addition to that, this fix also adds code to wi_write_wep() to force
existing keys to be switched between h/w and s/w crypto such that an
operation mode change(sta <-> hostap) will flag IEEE80211_KEY_SWCRYPT
properly.
- WEP RX fix:
Clear IEEE80211_F_DROPUNENC even in hostap mode. Quote from Sam:
"This is really gross but I don't see an easy way around it.
By doing it we lose the ability to independently drop unencode
frames (and support mixed wep/!wep use). We should really be
setting the EXCLUDE_UNENCRYPTED flag written in wi_write_wep
based on IEEE80211_F_DROPUNENC but with our clearing it we can't
depend on it being set properly."

- Remove description of poll in trap feature.
- Tell that polling should be turned on and off with ifconfig.
- Move description of kern.polling.enable to the end and say
that this a deprecated way of turning polling on.
- Remove note that idle poll has some problems in CURRENT. I failed
to find them, while Sam and Luigi failed to remember what the
problem actually were there.
o Axe poll in trap.
o Axe IFF_POLLING flag from if_flags.
o Rework revision 1.21 (Giant removal), in such a way that
poll_mtx is not dropped during call to polling handler.
This fixes problem with idle polling.
o Make registration and deregistration from polling in a
functional way, insted of next tick/interrupt.
o Obsolete kern.polling.enable. Polling is turned on/off
with ifconfig.
Detailed kern_poll.c changes:
- Remove polling handler flags, introduced in 1.21. The are not
needed now.
- Forget and do not check if_flags, if_capenable and if_drv_flags.
- Call all registered polling handlers unconditionally.
- Do not drop poll_mtx, when entering polling handlers.
- In ether_poll() NET_LOCK_GIANT prior to locking poll_mtx.
- In netisr_poll() axe the block, where polling code asks drivers
to unregister.
- In netisr_poll() and ether_poll() do polling always, if any
handlers are present.
- In ether_poll_[de]register() remove a lot of error hiding code. Assert
that arguments are correct, instead.
- In ether_poll_[de]register() use standard return values in case of
error or success.
- Introduce poll_switch() that is a sysctl handler for kern.polling.enable.
poll_switch() goes through interface list and enabled/disables polling.
A message that kern.polling.enable is deprecated is printed.
Detailed driver changes:
- On attach driver announces IFCAP_POLLING in if_capabilities, but
not in if_capenable.
- On detach driver calls ether_poll_deregister() if polling is enabled.
- In polling handler driver obtains its lock and checks IFF_DRV_RUNNING
flag. If there is no, then unlocks and returns.
- In ioctl handler driver checks for IFCAP_POLLING flag requested to
be set or cleared. Driver first calls ether_poll_[de]register(), then
obtains driver lock and [dis/en]ables interrupts.
- In interrupt handler driver checks IFCAP_POLLING flag in if_capenable.
If present, then returns.This is important to protect from spurious
interrupts.
