wlan: apply iwn,bwi,mwl commits from FreeBSD 13

iwn(4): (partially) rewrite A-MPDU Tx path

Generic Tx stats fixes:
- do not try to parse "aggregation status" for single frames; send them
to iwn_tx_done() instead;
- try to attach mbuf / node reference pair to reported BA events;
allows to fix reported status for ieee80211_tx_complete() and ifnet counters
(previously all A-MPDU frames were counted as failed - see PR 210211);
requires few more firmware bug workarounds;
- preserve short / long retry counters for wlan_amrr(4)
(disabled for now - causes significant performance degradation).
- Add new IWN_DEBUG_AMPDU debug category.
- Add one more check into iwn_tx_data() to prevent aggregation ring
overflow.
- Workaround 'seqno % 256' != 'current Tx slot' case (until D9195 is not
in the tree).
- Improve watchdog timer updates (previously watchdog check was omitted
when at least one frame was transmitted).
- Stop Tx when memory leak in currently used ring was detected (unlikely
to happen).
- Few other minor fixes.

Was previously tested with:
- Intel 6205, STA mode (Tx aggregation behaves much better now).
- Intel 4965AGN, STA mode (still unstable).

iwn(4): plug initialization path vs interrupt handler races

There are few places in interrupt handler where the driver
lock is dropped; ensure that device is still running before
processing remaining ring entries.

iwn: Set default ampdu parameters.

These are from the linux iwlwifi driver ;the default use smaller
maximum AMPDUs (8k) and a much smaller density (none.) The latter
could cause stability issues.

Tested:

* Tested on Intel 6300, STA mode.

bwi: clean up empty lines in .c and .h files

mwl: clean up empty lines in .c and .h files

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.

iprowifi2200: Upgrade to FreeBSD 12.

iprowifi2200: Sync with FreeBSD 11.1.

Untested, but the changes are relatively minimal (mostly adapations
to the new FreeBSD KPIs), and ttcoder recently opened a ticket (#14258)
about it, so he can test.

Update FreeBSD network drivers with the 9.3 release

merged changes from 8.2 FreeBSD release for most wlan drivers and net80211.
updated several firmwares for iprowifi4965 and iprowifi3945. Tested on iprowifi4965 only.

Fixed typo. This will make iprowifi2200 compile again.

* Ensuring reading of interrupt status is done only once.
* Code style cleanup.
* Automatic white space cleanup.

* Importing r401 of all compiling drivers from osdrawer.net/haiku-wifi.
The driver sources are based upon the FreeBSD RELEASE_8_0_0 source as found in
Haiku's freebsd vendor branch.
* Currently only the atheros driver is working and can be compiled with
jam atheros.
* Every driver contains a Jamfile already, so that the compilation process
can be started with jam <driver_name>. Also note, that linking of every
driver besides atheros and iprowifi2200 will fail at the moment.
