[net80211] add VHT ioctl parameters and driver capabilities

* Add the VHT capability element to the driver capabilities so ifconfig
can see if VHT is available
* Add ioctl plumbing for enabling/disabling VHT and each of the VHT
widths.

Note: this DOES change the ABI (the driver caps ioctl struct size, sigh)
so this will require a recompile of at least ifconfig.

[net80211] turn the default TX key configuration (for WEP) into a vap callback.

The ath10k firmware supports hardware WEP offload, and in native wifi mode
(or 802.3 ethernet mode, for that matter) the WEP key isn't actually included
in the TX payload from net80211. Instead, a separate firmware command is issued
that sets the default TX key to be the specified key.

However, net80211 doesn't at all inform the driver layer that this is
occuring - it just "expects" to be inserting WEP header information
when doing WEP TX, even with hardware encryption.

So, to better support the newer world order, turn the default TX key assignment
into a VAP method that can be overridden by the driver and ensure its wrapped
in a crypto begin/end set. That way it should be correctly atomic from the
point of view of keychanges (as long as the driver does the right thing.)

It'd be nice if we passed through to the key_set call a flag that says
"also make this the default key" - that's captured here by calling the
deftxkey method after the key_set method. Maybe I can do that later.

Note: this is a net80211 ABI change, and will require a kernel+modules
recompile. Happy Holidays, etc.

Tested:

* ath10k driver port
* rtwn_usb, WEP station

[net80211] put in a comment about the not-quite-correctness of A-MPDU parameters.

Although we correctly (now!) calculate the right A-MPDU parameters, the
ioctl() has some faulty logic for choosing which to display. The BSS
params are what were advertised to us, and we would have chosen the
lower of theirs/ours when advertising the HT bits back at them.

So, we /should/ track and fix that so we display the correct A-MPDU
density and size.

However, since I'm a forgetful type, and I don't want to have to re-learn
that this is wrong, drop in a comment so I or someone else fixes it.
Or, when I discover this again in 4 years, I don't have to go digging
too much to remember.
