b0602bec18 Move the HAL channel survey support out to be in the top-level HAL,
rathe than private in each HAL module.

Whilst here, modify ath_hal_private to always have the per-channel
noisefloor stats, rather than conditionally.  This just makes
life easier in general (no strange ABI differences between different
HAL compile options.)

Add a couple of methods (clear/reset, add) rather than using
hand-rolled versions of things.

5f63869372 Add a new field to HAL_ANISTATS - the extension channel busy count.
This is only used by the AR9300 HAL for now - but just be careful if
you decide to recompile the kernel with NO_CLEAN=1.

9bbfde1eb9 Fix more ticks wrapping bugs exposed by the ticks wrapping bug check.
This symptom is "calibrations don't ever run", which may cause some
pretty spectacularly bad behaviour in noisy environments or with longer
uptimes.

Thanks to dtrace to make it easy to check if specific non-inlined functions
are getting called by things like the ANI and calibration HAL methods.
Grr.

b072e86d09 Make kevent(2) a cancellation point.
Note that to cancel blocked kevent(2) call, changelist must be empty,
since we cannot cancel a call which already made changes to the
process state.  And in reverse, call which only makes changes to the
kqueue state, without waiting for an event, is not cancellable.  This
makes a natural usage model to migrate kqueue loop to support
cancellation, where existing single kevent(2) call must be split into
two: first uncancellable update of kqueue, then cancellable wait for
events.

Note that this is ABI-incompatible change, but it is believed that
there is no cancel-safe code that relies on kevent(2) not being a
cancellation point.  Option to preserve the ABI would be to keep
kevent(2) as is, but add new call with flags to specify cancellation
behaviour, which only value seems to add complications.

9cecaef7d6 Fix a long-standing bug with the early MAC address initialisation path,
which showed up after I started changing addresses this early.

It turns out that there's some other malarky going on behind the scenes
in the HAL and merely setting the net80211/ifp mac address this early
isn't enough.  If the MAC is set from kenv at attach time, the HAL
also needs to be programmed early.

Without this, the VAP wouldn't work enough for finishing association -
probe requests would be fine as they're broadcast, but association
request would fail.

912a62418a cdefs.h: Fix macros for pre-C99 compilers.
Older compilers, and compatibility modes, may not support variadic macros.
I normally wouldn't go out of my way to support those old compilers but
there is a prescendent in other system headers for using the same macro
multiple times, and the solution (although non-elegant IMHO) works.

240b1f1dca Update if_ath(4) to check for "hint.ath.X.macaddr" for an override MAC address.
This is used by the AR71xx platform code to choose a local MAC based on

values are stored in the Atheros calibration data.

b7d7ad0b90 Begin moving support for board MAC addresses over to being explicitly defined.
A lot of these dinky atheros based MIPS boards don't have a nice, well,
anything consistent defining their MAC addresses for things.

The Atheros reference design boards will happily put MAC addresses
into the wifi module calibration data like they should, and individual
ethernet MAC addresses into the calibration area in flash.
That makes my life easy - "hint.arge.X.eeprommac=<addr>" reads from
that flash address to extract a MAC, and everything works fine.

However, aside from some very well behaved vendors (eg the Carambola 2
board), everyone else does something odd.

eg:

* a MAC address in the environment (eg ubiquiti routerstation/RSPRO)
   that you derive arge0/arge1 MAC addresses from.
* a MAC address in flash that you derive arge0/arge1 MAC addresses from.
* The wifi devices having their own MAC addresses in calibration data,
  like normal.
* The wifi devices having a fixed, default or garbage value for a MAC
  address in calibration data, and it has to be derived from the
  system MAC.

So to support this complete nonsense of a situation, there needs to be
a few hacks:

* The "board" MAC address needs to be derived from somewhere and squirreled
  away.  For now it's either redboot or a MAC address stored in calibration
  flash.

* Then, a "map" set of hints to populate kenv with some MAC addresses
  that are derived/local, based on the board address.  Each board has
  a totally different idea of what you do to derive things, so each
  map entry has an "offset" (+ve or -ve) that's added to the board
  MAC address.

* Then if_arge (and later, if_ath) should check kenv for said hint and
  if it's found, use that rather than the EEPROM MAC address - which may
  be totally garbage and not actually work right.

In order to do this, I've undone some of the custom redboot expecting
hacks in if_arge and the stuff that magically adds one to the MAC
address supplied by the board - instead, as I continue to test this
out on more hardware, I'll update the hints file with a map explaining
(a) where the board MAC should come from, and (b) what offsets to use
for each device.

The aim is to have all of the tplink, dlink and other random hardware
we run on have valid MAC addresses at boot, so (a) people don't get
random B:S:Dx:x ethernet MACs, and (b) the wifi MAC is valid
so it works rather than trying to use an invalid address that
actually upsets systems (think: multicast bit set in BSSID.)

Tested:

* TP-Link TL_WDR3600 - subsequent commits will add the hints map
  and the if_ath support.

TODO:

* Since this is -HEAD, and I'm all for debugging, there's a lot of
  printf()s in here.  They'll eventually go under bootverbose.
* I'd like to turn the macaddr routines into something available
  to all drivers - too many places hand-roll random MAC addresses
  and parser stuff.  I'd rather it just be shared code.
  However, that'll require more formal review.
* More boards.

flag (the one expected to be played with by callers in MPSAFE) without
a lock, it won't adversely affect the callout system by causing a corrupt
list. This also means that all callers need to use the macros and *not*
play with the falgs directly (like netgraph used to).
