After my bit scan re-writing the SIOCSIWSCAN wext ioctl no longer supported
scanning for a specific SSID. However, wpa_supplicant is a possible user of
this ioctl, so here is code that add's this.

While passing, removed even more of the debugfs-based scanning. You can (and
should) the SIOCSIWSCAN to ask for scans, so there is no need for
proprietary interfaces for scanning. And, besides, the scan result couldn't
be used further, e.g. not for associating.

This is a change to a previous patch ("iwlwifi: 3945 split tx_complete
to command and packet function") to ensure we do not have hardirq safe
locks (priv->lock in this case) depend on hardirq unsafe locks.

We only call iwl3945_tx_queue_reclaim while in a tasklet so we have to use
the irqsafe version of the function.

atheros hardware has a problem with the rx timestamp of some IBSS beacons when
they caused a TSF update (they have the same BSSID).

the rx timestamp is wrong especially if the beacon frames get bigger than 78
byte (at least on AR5213 and AR5414 hardware). in that case ath5k_extend_tsf()
will assume a rs_tstamp overflow and give us a timestamp too far in the past
which will cause mac80211 to merge IBSS on every beacon (which is not necessary
since the BSSID already matches). but in this case we know that the HW must
have synced to the beacons TSF and the rx timestamp must be later than that so
we can adjust mactime accordingly.

also rename the function to ath5k_check_ibss_tsf() and change comments, since
"hw merge" is better described as a TSF update.

move ath5k_tx_status and ath5k_rx_status structures out of the hardware
descriptor since they are not accessed by the hardware at all. they just
contain converted information from the hardware descriptor. since they are only
used in the rx and tx tasklets there is also no use to keep them for each
descriptor.

* make struct ath5k_desc clearer by directly including unions of structures,
  which correspond to the hardware descriptors of different HW versions (5210
  and 5212). before they were casted at onto ath5k_desc at different points
  (e.g.  ds_hw[2]).

* rename some structures and variable names to make their use clearer, e.g.
  struct ath5k_hw_4w_tx_desc to ath5k_hw_4w_tx_ctl.

* substitute "old" with "5210" and "new" with "5212" (eg. rename
  ath5k_hw_proc_new_rx_status() to ath5k_hw_proc_5212_rx_status()) because old
  and new are relative and we might have a newer structure at some point.

* unify structs ath5k_hw_old_rx_status and ath5k_hw_new_rx_status into one
  ath5k_hw_rx_status, because they only differ in the flags and masks.

The patch also addes HT flags, for 802.11n drivers:
- IEEE80211_TXCTL_OFDM_HT: request low-level driver to use HT OFDM rates
- IEEE80211_TXCTL_GREEN_FIELD: use green field protection
- IEEE80211_TXCTL_DUP_DATA: duplicate data on both 20 Mhz channels
- IEEE80211_TXCTL_40_MHZ_WIDTH: send this frame in 40Mhz width
- IEEE80211_TXCTL_SHORT_GI: send this frame with short guard interval

Tx command can be a combination of any of these flags, along with
bitrate represented by ieee80211_rate. this will allow legacy drivers to
switch easily to any 11n rate representation.
