As pointed out by Modestas Vainius the link tuner
could continue working while the radio is already
down. This because at the start of disable_radio
the ENABLED_RADIO flag is cleared and causes the
toggle_rx to skip the stop_link_tuner() call.
This will add a check to the start of the link tuner
which will automatically stop the link tuner when the
radio is disabled.

Drivers are currently supposed to keep track of monitor
interfaces if they allow so-called "hard" monitor, and
they are also supposed to keep track of multicast etc.
This patch changes that, replaces the set_multicast_list()
callback with a new configure_filter() callback that takes
filter flags (FIF_*) instead of interface flags (IFF_*).
For a driver, this means it should open the filter as much
as necessary to get all frames requested by the filter flags.
Accordingly, the filter flags are named "positively", e.g.
FIF_ALLMULTI.
Multicast filtering is a bit special in that drivers that
have no multicast address filters need to allow multicast
frames through when either the FIF_ALLMULTI flag is set or
when the mc_count value is positive.
At the same time, drivers are no longer notified about
monitor interfaces at all, this means they now need to
implement the start() and stop() callbacks and the new
change_filter_flags() callback. Also, the start()/stop()
ordering changed, start() is now called *before* any
add_interface() as it really should be, and stop() after
any remove_interface().
The patch also changes the behaviour of setting the bssid
to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING
is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed
and the filter flag FIF_BCN_PRBRESP_PROMISC introduced.
This is a lot more efficient for hardware like b43 that
supports it and other hardware can still set the BSSID
to all-ones.

This change cleans up the radio-related messages in several ways.
(1) The state of the rfkill switch is assumed to be on, rather than
tested. Now, any user without such a switch will not see any
messages. For devices with such a switch, a message will be
logged only if the initial state is off, or if the switch is toggled.
(2) The routine for testing the switch state is no longer inline.
(3) The LED handling routine is simplified.
(4) The "Radio turned off" message that has confused some users has been
changed to "Radio initialized".
