This patch enables listing DFS related flags when 'ifconfig -v wlanX

Browse Source 
list channel' is run. The following new options are introduced:

* D: channel requires DFS
* R: channel has a radar event
* I: channel has detected inteference
* C: the CAC period has completed on a channel that requires it (ie,
  DFS + PASSIVE.)

It's relevant for developing, debugging and using the DFS and
interference options.
