b43: Optimize DMA buffers

In the old days we used one slot per frame. But when we changed that to 2,
we didn't raise the overall slot count. Which resulted in an effective
division of two to the number of slots.

Double the number of TX slots, so we have an effective hardware queue
of 128 frames per QoS queue.

Also optimize the TX header cache handling. We don't need a cached TX header
for slots that will never carry an actual header.
So we reduce the memory consumption of the cache by 50%.

So as a net result we end up with more or less the same memory usage before
and after this patch (except a few tiny meta structures), but have twice

Rework:
- There is not a case when IWLCORE should not be selected. At the same time
  the driver does not use IWLWIFI or IWLCORE. We can just merge the usage of

  replace instances of IWLCORE with it. The module name does not change
  and is still iwlcore.
- Both IWLAGN and IWL3945 are selecting FW_LOADER, we can thus just move
  this up to one select when IWLWIFI is selected.
- IWL5000 now supports Intel Wireless Wifi 100, 6000, and 6050 series.
- Now that 3945 depends on IWLWIFI we can also indicate its dependency on
  MAC80211_LEDS and LEDS_CLASS at this level.
- IWLAGN_LEDS is not used by driver - remove it.
- IWLAGN_SPECTRUM_MEASUREMENT actually depends on IWLWIFI as it forms part
  of iwlcore module. Move this config up in Kconfig to reflect that and also
  change name to IWLWIFI_SPECTRUM_MEASUREMENT.
- CONFIG_IWLWIFI_RFKILL is used by iwlagn as well as iwl3945, add text to
  description that indicates this.
- CONFIG_IWL3945_RFKILL does not exist - remove usage from driver.
- Add "iwlagn" to end of description of IWLAGN to help people understand

- Add "iwl3945" to end of description of IWL3945 to help people understand

mac80211: fix aggregation for hardware with ampdu queues

Hardware with AMPDU queues currently has broken aggregation.

This patch fixes it by making all A-MPDUs go over the regular AC queues,
but keeping track of the hardware queues in mac80211. As a first rough
version, it actually stops the AC queue for extended periods of time,
which can be removed by adding buffering internal to mac80211, but is
currently not a huge problem because people rarely use multiple TIDs
that are in the same AC (and iwlwifi currently doesn't operate as AP).

This is a short-term fix, my current medium-term plan, which I hope to
execute soon as well, but am not sure can finish before .30, looks like
this:
 1) rework the internal queuing layer in mac80211 that we use for
    fragments if the driver stopped queue in the middle of a fragmented
    frame to be able to queue more frames at once (rather than just a
    single frame with its fragments)
 2) instead of stopping the entire AC queue, queue up the frames in a
    per-station/per-TID queue during aggregation session initiation,
    when the session has come up take all those frames and put them
    onto the queue from 1)
 3) push the ampdu queue layer abstraction this patch introduces in
    mac80211 into the driver, and remove the virtual queue stuff from
    mac80211 again

This plan will probably also affect ath9k in that mac80211 queues the
frames instead of passing them down, even when there are no ampdu queues.
