When we have CAC active and receive a radar event, we should ignore
CAC_ABORT event and handle channel switch in the radar event handler.

This fixes a problem when operating on non-DFS channel and receiving a
radar event for that channel. Previously, we would have decided to
switch channels.

Add a table of available VHT80 channels. This table contains the first
available channel. We will also choose this first channel as the control
one.

The VHT_CHANWIDTH_160MHZ case fell through to the default case and
printed out a debug message that was not supposed to be shown here.

Add DFS structures/events handlers, CAC handling, and radar detection.
By default, after radar is detected or the channel became unavailable, a
random channel will be chosen.
This patches are based on the original work by Boris Presman and
Victor Goldenshtein. Most of the DFS code is moved to a new dfs.c/dfs.h
files.
