The patch rewrites the mac80211 configure_filter handler to better mapping
mac80211 filter flags to iwlwifi hardware filter flags. We now can support
5 mac80211 filter flags: FIF_OTHER_BSS, FIF_ALLMULTI, FIF_PROMISC_IN_BSS,
FIF_BCN_PRBRESP_PROMISC and FIF_CONTROL. This patch also avoids reconnecting
if the filter flags are changed when the STA is associated. Because rx_assoc
is used when full rxon is not necessary.

The callback function write_tx_data() can only fail
when our ENTRY_OWNER_DEVICE_DATA flag on a queue entry
failed to determine the entry was not available and
it is in fact still owned by the hardware.
This means that if that function fails the queue
must be stopped in mac80211.

When rt2x00queue_get_queue() returns NULL in the TX
path, it means mac80211 has passed us an invalid queue,
although this should be impossible, it shouldn't hurt
if we send mac80211 a signal to stop the queue either.

Both issues can simply be resolved by removing their
manual failure handler and making them use the failure path
provided in rt2x00mac_tx().

rt2500usb and rt73usb have different register word sizes,
for that reason the register access wrappers were never
moved into rt2x00usb.
With rt2800usb on its way, we should favor the 32bit
register access and move those wrappers into rt2x00usb.
That saves duplicate code, since only rt2500usb will
need the special 16bit wrappers.

Indirect registers require multiple calls to the CSR
register in order to access the indirect registers.
This must be protected under a lock to prevent race
conditions which could cause invalid data to
be returned when reading from the indirect register or silent
failures when writing data to the indirect register.

USB drivers where already protected under a mutex,
so rename the mutex and make PCI drivers use the mutex
as well.
This now means that BBP and RF registers are no longer
accessible in interrupt context. That is not a bad
situation since the slow behavior of accessing
those registers means we don't _want_ to access them
in interrupt context either.

We can optimize get_duration and get_duration_res
by making them a macro. They are really simple
calculation handlers so this doesn't matter much.

Often (especially in rt2400pci and rt2500pci,
the arguments are hardcoded, and the result value
is passed into other hardcoded values.

By making the functions a macro GCC can
optimize the entire thing much better.

Merge the callback functions init_txentry() and
init_rxentry(). This makes life in rt2x00lib a
lot simpler and we can cleanup several functions.

rt2x00pci contained "fake" FIELD definitions for
descriptor words. This is not flexible since it
assumes the driver will always have the same field
to indicate if a driver is available or not.
This should be dependent on the driver, and we
should add a callback function for this.

*On a previous patch i splitted AR5K_INT_TX to multiple different TX
interrupt flags for better handling but i forgot to unmask the new
TXDESC and TXEOL interrupts on ath5k_init and only left TXOK. However
for each queue we enable TXDESC and TXEOL interrupts, not TXOK so we don't
handle TX interrupts at all (because these interrupts remain masked on
PISR) and under load it results packet loss. Fix the problem by
unmasking TXDESC and TXEOL on ath5k_init.
