This patch gets rid of the if_id stuff where possible in favour of
a new per-virtual-interface structure "struct ieee80211_vif". This
structure is located at the end of the per-interface structure and
contains a variable length driver-use data area.
This has two advantages:
* removes the need to look up interfaces by if_id, this is better
for working with network namespaces and performance
* allows drivers to store and retrieve per-interface data without
having to allocate own lists/hash tables

suspend & resume was broken since it called rt2x00mac_start()
and rt2x00mac_stop() which would fail to execute because the
DEVICE_PRESENT flag was not set.
Move the start and stop handlers into rt2x00lib.c which are called
from rt2x00mac_start() and rt2x00mac_stop() after they have checked
the DEVICE_PRESENT flag, while suspend and resume handlers can
directly call those functions.

Apparently it was possible that ieee80211_stop_queue() was not full while
NETDEV_TX_BUSY was being reported back. I think that is what causing the WARN_ON().
This moves all calls to ieee80211_stop_queue() in rt2x00mac.c where it is easier
to determine if the queue should be halted.

No need to use a seperate define INVALID_INTERFACE while
we can use IEEE80211_IF_TYPE_INVALID directly.

DRV_NAME was always set to the KBUILD_MODNAME value,
lets clean everything up by removing DRV_NAME and just
use KBUILD_MODNAME directly.

rt2x00 is broken when it comes down to adhoc and master mode.
The main problem is the beaconing, which is completely failing.
Untill a solution has been found, both beacon requiring modes
must be disabled to prevent numerous bug reports.

Reorganize configuration handling by creating a extra
structure which contains precalculated values based
on the mac80211 values which are usefull for all
individual drivers.
This also fixes the preamble configuration problem,
up untill now preamble was never configured since
by default the rate->val value was used when changing
the mode.
Now rate->val will only be used to set the basic rate mask.
The preamble configuration will now be done correctly
through the erp_ie_changed callback function.

Directly pass a value from the enum dev_state with rt2x00lib_toggle_rx,
this will save us a ? : statement, and it is clearer then passing a 1 0
argument.

The rt2x00dev->flags has become a chaos over time,
this will reorganize the flags by renaming, deleting, adding
and properly implement the flags.

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.
