As discussed earlier, we can unify locking in struct sta_info
and use just a single spinlock protecting all members of the
structure that need protection. Many don't, but one of the
especially bad ones is the 'flags' member that can currently
be clobbered when RX and TX is being processed on different
CPUs at the same time.

Because having four spinlocks for different, mostly exclusive
parts of a single structure is overkill, this patch also kills
the ampdu and mesh plink spinlocks and uses just a single one
for everything. Because none of the spinlocks are nested, this
is safe.

It remains to be seen whether or not we should make the sta
flags use atomic bit operations instead, for now though this
is a safe thing and using atomic operations instead will be
very simple using the new static inline functions this patch
introduces for accessing sta->flags.

Since spin_lock_bh() is used with this lock, there shouldn't
be any contention even if aggregation is enabled at around the
same time as both requires frame transmission/reception which
is in a bh context.

This
 * makes the queue number passed to drivers a u16
   (as it will be with skb_get_queue_mapping)
 * removes the useless queue number defines
 * splits hw->queues into hw->queues/ampdu_queues
 * removes the debugfs files for per-queue counters
 * removes some dead QoS code
 * removes the beacon queue configuration for IBSS
   so that the drivers now never get a queue number
   bigger than (hw->queues + hw->ampdu_queues - 1)
   for tx and only in the range 0..hw->queues-1 for
   conf_tx.
