This patch makes mac80211 assign proper sequence numbers to
QoS-data frames. It also removes the old sequence number code
because we noticed that only the driver or hardware can assign
sequence numbers to non-QoS-data and especially management
frames in a race-free manner because beacons aren't passed
through mac80211's TX path.
This patch also adds temporary code to the rt2x00 drivers to
not break them completely, that code will have to be reworked
for proper sequence numbers on beacons.
It also moves sequence number assignment down in the TX path
so no sequence numbers are assigned to frames that are dropped.

For RTL8187B it seems we need special values too for ANAPARAM*_OFF
values (and not use RTL8187 ones). The ANAPARAM*_OFF values used are the
stock ones read from the hardware after a cold boot.

With the new beacon handling from mac80211 we can
reorganize the beacon handling in rt2x00 as well.
This patch will move the function to the TX handlers,
and move all duplicate code into rt2x00queue.c.
After this change the descriptor helper functions
from rt2x00queue.c no longer need to be exported
outside of rt2x00lib and can be declared static.

This patch changes mac80211's beacon configuration handling
to never pass skbs to the driver directly but rather always
require the driver to use ieee80211_beacon_get(). Additionally,
it introduces "change flags" on the config_interface() call
to enable drivers to figure out what is changing. Finally, it
removes the beacon_update() driver callback in favour of
having IBSS beacon delivered by ieee80211_beacon_get() as well.

As soon as an interface is enabled, and that interface is in adhoc or master mode,
the device will start raising beacondone interrupts. But before the first interrupt is
raised, mac80211 will probably not have send any beacons to the device yet, which
results in a NULL pointer error when the skb is being freed.
Note that the "raise beacondone interrupts without a beacon" is also a bug,
and will be addressed later. The more important bug however is preventing
the NULL pointer failt itself, since there might be other conditions that could trigger
it as well.

Some early versions of RTL8187B devices have a USB ID of 0x8187
rather than the 0x8189 of later models. In addition, it appears
that these early units also must be programmed with lower power.
Previous patches used the Product ID string to detect this situation,
but did not address the low power question. This patch uses the
hardware version and sets the power accordingly.

This patch fixes the iwlwifi rfkill. It removes the input device from iwl3945,
adds support for RFKILL_STATE_HARD_BLOCKED and calls rfkill_force_state() to
update the state rather than accessing it directly.
The calls to iwl|iwl3945_rfkill_set_hw_state() had to be moved because
rfkill_force_state() cannot be called from an atomic context.
Tested on iwl3945 and seems to work fine.
