nl80211: Parse channel type attribute in an ibss join request
Prepare cfg80211 for IBSS HT:
* extend cfg80211 ibss struct with channel_type
* Check if extension channel can be used
* Export can_beacon_sec_chan for use in mac80211 (will be called
from ibss.c later).

[siwu@hrz.tu-chemnitz.de: Updates]
* fix cfg80211_can_beacon_ext_chan comment
* remove implicit channel_type enum assumptions
* remove radar channel flags check
* add HT IBSS feature flag
* reword commit message
