[PATCHv9 0/3] Add DFS master ability

[Simon Wunderlich <simon.wunderlich@s2003.tu-chemnitz.de>]

This is patch series version 9 of the DFS master ability, based on Victor
Goldenshteins original work. See changelog in the various patches for
details. The main changes to v8 are:

 * checked and fixed locking - note the new patch 1 changing the locking
   for use/release_channel to remove rtnl dependency
 * report radar detected and NOP only once
 * fix gfp usage
 * merge "nl80211: allow DFS in start_ap" in the main nl80211 patch
 * various style changes
 * rebased on latest master, of course

As always, thanks a lot to Johannes for review and support. 
I've verified the implementation (again) with ath9k a patched hostapd (patches
to be released later). This time also lock verified (I used a tainted kernel
before, so locking was disabled ...).

iw patches for interface combinations and DFS state handling are attached as well.

One open issue (still) remains: On my system, DFS channels are flagged with NO_IBSS and
DISABLED, this is due to my country code setting to 00. I can manually circumvent
that, but should we find a proper solution for this? This regularity intersection
gives me quite a bit of a headache ...
