This ports the b43/legacy rfkill code to the new API offered
by cfg80211 and thus removes a lot of useless stuff.

This patch completely rewrites the rfkill core to address
the following deficiencies:
* all rfkill drivers need to implement polling where necessary
rather than having one central implementation
* updating the rfkill state cannot be done from arbitrary
contexts, forcing drivers to use schedule_work and requiring
lots of code
* rfkill drivers need to keep track of soft/hard blocked
internally -- the core should do this
* the rfkill API has many unexpected quirks, for example being
asymmetric wrt. alloc/free and register/unregister
* rfkill can call back into a driver from within a function the
driver called -- this is prone to deadlocks and generally
should be avoided
* rfkill-input pointlessly is a separate module
* drivers need to #ifdef rfkill functions (unless they want to
depend on or select RFKILL) -- rfkill should provide inlines
that do nothing if it isn't compiled in
* the rfkill structure is not opaque -- drivers need to initialise
it correctly (lots of sanity checking code required) -- instead
force drivers to pass the right variables to rfkill_alloc()
* the documentation is hard to read because it always assumes the
reader is completely clueless and contains way TOO MANY CAPS
* the rfkill code needlessly uses a lot of locks and atomic
operations in locked sections
* fix LED trigger to actually change the LED when the radio state
changes -- this wasn't done before

Fixed led device naming for the b43legacy driver. Due to the
documentation of the led subsystem/class the naming should be
"devicename:colour:function" while not applying sections
should be left blank.
This should lead to e.g. "b43legacy-%s::rx" instead of
"b43legacy-%s:rx".

This fixes Bug #9414 for b43legacy. This patch is the equivalent of one
submitted earlier for b43.
Since addition of the rfkill callback, the LED associated with the off
switch on the radio has not worked for several reasons:
(1) Essential data in the rfkill structure were missing.
(2) The rfkill structure was initialized after the LED initialization.
(3) There was a minor memory leak if the radio LED structure was inited.
Once the above problems were fixed, additional difficulties were noted:
(4) The radio LED was in the wrong state at startup.
(5) The radio switch had to be manipulated twice for each state change.
(6) A circular mutex locking situation existed.
(7) If rfkill-input is built as a module, it is not automatically loaded.
This patch fixes all of the above and removes a couple of sparse warnings.

This adds full support for the RFKILL button and the RFKILL LED trigger.
This is a port to b43legacy of a patch by Michael Buesch <mb@bu3sch.de>
for b43.

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".
This patch is patterned after a similar change to b43 by Michael Buesch.
