Submission: lib80211 (regulatory domain code) and wlanreg tool

[Adrian Chadd]

I'd appreciate some feedback on the following patch.

http://people.freebsd.org/~adrian/ath/lib80211-1.diff

It implements the following:

* extract out the regulatory database code from ifconfig, call it "lib80211"
;
* add a new includedir, /usr/include/lib80211/ ;
* add a tool, wlanreg, which prints out the regulatory information for a
given SKU/country.

Example output:

./wlanreg sku SR9
SKU: SR9

I'll patch ifconfig to use the lib80211 library/includes in a follow-up
commit, so code isn't duplicated.

Thanks!
