Fix ieee80211_radiotap(9) usage in wireless drivers:

- Alignment issues:
* Add missing __packed attributes + padding across all drivers; in
most places there was an assumption that padding will be always
minimally suitable; in few places - e.g., in urtw(4) / rtwn(4) -
padding was just missing.
* Add __aligned(8) attribute for all Rx radiotap headers since they can
contain 64-bit TSF timestamp; it cannot appear in Tx radiotap headers, so
just drop the attribute here. Refresh ieee80211_radiotap(9) man page
accordingly.

- Since net80211 automatically updates channel frequency / flags in
ieee80211_radiotap_chan_change() drop duplicate setup for these fields
in drivers.

Tested with Netgear WG111 v3 (urtw(4)), STA mode.

Enforce net80211 rates for control / management / multicast / EAPOL frames
and allow to override rate for unicast frames via ifconfig(8) 'ucastrate'

rsu: increase Rx buffer size from 8k to 30k.

This is required for USB Rx aggregation
(and fixes 'could not allocate RX mbuf' / few other failures).

While here, reduce the number of Rx buffers from 100 to 1 -
the driver never uses more than one Rx buffer.

Tested with Asus USB-N10.

rsu: add hardware crypto support (WEP, TKIP and CCMP).

This change includes firmware commands for key setup +
some additional checking via CAMREAD / CAMWRITE registers.
Nothing (except rsu_delete_key() for pairwise keys) is deferred;
to ensure that things are done in order rsu_set_key() will wait
until key deletion task will be finished.

Tested with Asus USB-N10 (all ciphers).

Differences from initial (reviewed) patch:
- Pause AC queues before disassociation - since CMD_DISCONNECT clears
crypto state all pending frames must be processed / dropped before it.
- Check sc_running flag before trying to set static keys.
- Clear key index from bitmap even when firmware command fails
(it will be invalidated via CAMWRITE anyway).

rsu: fix RSSI reporting, partially revert r288414.

- Append RCR_APP_PHYSTS bit after firmware loading - otherwise
firmware will reset the register and this modification will be lost.
(without it Rx PHY descriptor section will contain garbage).
- Check if R92S_RXDW0_PHYST bit is set (like it is done in rtwn(4)) -
even if infosz is non-zero the section may not contain anything useful.
- In case, if descriptor is absent (A-MPDU?) use last calibrated RSSI
(rtwn(4) uses RSSI from the previous (sub)frame; probably, this
approach should be used here too).

Tested with Asus USB-N10, STA mode.

frames when associated.
- Check IEEE80211_SCAN_ACTIVE scan flag instead of IEEE80211_F_ASCAN
ic flag; the last is never set since r170530.
- Eliminate software scan (net80211) <-> site_survey (driver) race:
* override ic_scan_curchan and ic_scan_mindwell pointers so net80211
will not try to finish scanning automatically;
* inform net80211 about current status via ieee80211_cancel_scan()
and ieee80211_scan_done();
* remove corresponding workaround from rsu_join_bss().

Now the driver can associate to an AP with hidden SSID.
