0e56140a1b Fix a corner case in the HAL debugging changes, where ah was NULL.
Although I tried to fix this earlier by introducing HALDEBUG_G(), it
turns out there seem to be other cases where the pointer value is still
NULL.

* Fix DO_HALDEBUG() and the HALDEBUG macro to check whether ah is NULL
  before deferencing it
* Remove HALDEBUG_G() as it's no longer needed

This is hopefully a merge candidate for 9.0-RELEASE as enabling
debugging at startup could result in a kernel panic.

ffae5d00d2 Bitten again by the optional HALDEBUG compilation.
Remove this debugging, it's not needed anymore and when not enabled,
those variables trigger a compiler warning.

7dd4de1301 The older HAL code sets up the regulatory domain once; FreeBSD/net80211
allows it to be overridden at runtime.

Thus, add a function which updates ah_dfsDomain after a channel set
call to ath_hal_set_channels().

8db87e4079 Introduce some more DFS related hooks, inspired both by local work
and the Atheros reference code.

The radar detection code needs to know what the current DFS domain is.
Since net80211 doesn't currently know this information, it's extracted
from the HAL regulatory domain information.

The specifics:

* add a new ath_dfs API hook, ath_dfs_init_radar_filters(), which
  updates the radar filters whenever the regulatory domain changes.
* add HAL_DFS_DOMAIN which describes the currently configured DFS domain .
* add a new HAL internal variable which tracks the currently configured
  HAL DFS domain.
* add a new HAL capability, HAL_CAP_DFS_DMN, which returns the currently
  configured HAL DFS domain setting.
* update the HAL DFS domain setting whenever the channel setting is
  updated.

Since this isn't currently used by any radar code, these should all
be no-ops for existing users.

e8e6035991 This re-enables HT40 channels for use when DFS is enabled.
These should be disabled for the AR5416 in hostap/mesh/ibss mode,
as the AR5416 doesn't have support for radar detection on the
ext channel of a HT40 setup. Later chips do.

f6f1dfb66b Re-introduce a global ath_hal_debug again for now, whilst I figure out what
to do about the few cases where the HAL state isn't available (regdomain)
or isn't yet setup (probe/attach.)

The global ath_hal_debug now affects all instances of the HAL.

This also restores the ability for probe/attach debugging to work; as
the sysctl tree may not be attached at that point. Users can just set
the global "hw.ath.hal.debug" to a suitable value to enable probe/attach
related debugging.

c48e24c122 Migrate the regulatory database definitions into separate header files
to both make things clearer, and to make it easier to write userland
code which pulls in these definitions without needing to pull in the
rest of the HAL.

This stuff should be deprecated at some point in the future once
the net80211 regulatory domain support encapsulates all of the
defintions here.

59efa8b517 Overhaul regulatory support:
o remove HAL_CHANNEL; convert the hal to use net80211 channels; this
  mostly involves mechanical changes to variable names and channel
  attribute macros
o gut HAL_CHANNEL_PRIVATE as most of the contents are now redundant
  with the net80211 channel available
o change api for ath_hal_init_channels: no more reglass id's, no more outdoor
  indication (was a noop), anM contents
o add ath_hal_getchannels to have the hal construct a channel list without
  altering runtime state; this is used to retrieve the calibration list for
  the device in ath_getradiocaps
o add ath_hal_set_channels to take a channel list and regulatory data from
  above and construct internal state to match (maps frequencies for 900MHz
  cards, setup for CTL lookups, etc)
o compact the private channel table: we keep one private channel
  per frequency instead of one per HAL_CHANNEL; this gives a big
  space savings and potentially improves ani and calibration by
  sharing state (to be seen; didn't see anything in testing); a new config
  option AH_MAXCHAN controls the table size (default to 96 which
  was chosen to be ~3x the largest expected size)
o shrink ani state and change to mirror private channel table (one entry per
  frequency indexed by ic_devdata)
o move ani state flags to private channel state
o remove country codes; use net80211 definitions instead
o remove GSM regulatory support; it's no longer needed now that we
  pass in channel lists from above
o consolidate ADHOC_NO_11A attribute with DISALLOW_ADHOC_11A
o simplify initial channel list construction based on the EEPROM contents;
  we preserve country code support for now but may want to just fallback
  to a WWR sku and dispatch the discovered country code up to user space
  so the channel list can be constructed using the master regdomain tables
o defer to net80211 for max antenna gain
o eliminate sorting of internal channel table; now that we use ic_devdata
  as an index, table lookups are O(1)
o remove internal copy of the country code; the public one is sufficient
o remove AH_SUPPORT_11D conditional compilation; we always support 11d
o remove ath_hal_ispublicsafetysku; not needed any more
o remove ath_hal_isgsmsku; no more GSM stuff
o move Conformance Test Limit (CTL) state from private channel to a lookup
  using per-band pointers cached in the private state block
o remove regulatory class id support; was unused and belongs in net80211
o fix channel list construction to set IEEE80211_CHAN_NOADHOC,
  IEEE80211_CHAN_NOHOSTAP, and IEEE80211_CHAN_4MSXMIT
o remove private channel flags CHANNEL_DFS and CHANNEL_4MS_LIMIT; these are
  now set in the constructed net80211 channel
o store CHANNEL_NFCREQUIRED (Noise Floor Required) channel attribute in one
  of the driver-private flag bits of the net80211 channel
o move 900MHz frequency mapping into the hal; the mapped frequency is stored
  in the private channel and used throughout the hal (no more mapping in the
  driver and/or net80211)
o remove ath_hal_mhz2ieee; it's no longer needed as net80211 does the
  calculation and available in the net80211 channel
o change noise floor calibration logic to work with compacted private channel
  table setup; this may require revisiting as we no longer can distinguish
  channel attributes (e.g. 11b vs 11g vs turbo) but since the data is used
  only to calculate status data we can live with it for now
o change ah_getChipPowerLimits internal method to operate on a single channel
  instead of all channels in the private channel table
o add ath_hal_gethwchannel to map a net80211 channel to a h/w frequency
  (always the same except for 900MHz channels)
o add HAL_EEBADREG and HAL_EEBADCC status codes to better identify regulatory
  problems
o remove CTRY_DEBUG and CTRY_DEFAULT enum's; these come from net80211 now
o change ath_hal_getwirelessmodes to really return wireless modes supported
  by the hardware (was previously applying regulatory constraints)
o return channel interference status with IEEE80211_CHANSTATE_CWINT (should
  change to a callback so hal api's can take const pointers)
o remove some #define's no longer needed with the inclusion of
  <net80211/_ieee80211.h>
