This is a work in progress and some of this stuff may change;
but hopefully I'm laying down enough stuff and space in fields
to allow it to grow without another major recompile.
We'll see!
* Add a net80211 PHY type for VHT 2G and VHT 5G.
Note - yes, VHT is supposed to be for 5GHZ, however some vendors
(*cough* most of them) support some subset of VHT rate support
in 2GHz. No - not 80MHz wide channels, but at least some MCS8-9
support, maybe some beamforming, and maybe some longer A-MPDU
aggregates. I don't want to even think about MU-MIMO on 2GHz.
* Add an ifmedia placeholder type for VHT rates.
* Add channel flags for VHT, VHT20/40U/40D/80/80+80/160
* Add channel macros for the above
* Add ieee80211_channel fields for the VHT information and flags,
along with some padding (so this struct definitely grows.)
* Add a phy type flag for VHT - 'v'
* Bump the number of channels to a much higher amount - until we get
something like the linux mac80211 chanctx abstraction (where the
stack provides a current channel configuration via callbacks,
versus the driver ever checking ic->ic_curchan or similar) we'll
have to populate VHT+HT combinations.
Eg, there'll likely be a full set of duplicate VHT20/40 channels to match
HT channels. There will also be a full set of duplicate VHT80 channels -
note that for VHT80, its assumed you're doing VHT40 as a base, so we
don't need a duplicate of VHT80 + 20MHz only primary channels, only
a duplicate of all the VHT40 combinations.
I don't want to think about VHT80+80 or VHT160 for now - and I won't,
as the current device I'm doing 11ac bringup on (QCA9880) only does
VHT80.
I'll likely revisit the channel configuration and scanning related
stuff after I get VHT20/40 up.
* Add vht flags and the basic MCS rate setup to ieee80211com, ieee80211vap
and ieee80211_node in preparation for 11ac configuration.
There is zero code that uses this right now.
* Whilst here, add some more placeholders in case I need to extend
out things by some uint32_t flag sized fields. Hopefully I won't!
What I haven't yet done:
* any of the code that uses this
* any of the beamforming related fields
* any of the MU-MIMO fields required for STA/AP operation
* any of the IE fields in beacon frame / probe request/response handling
and the calculations required for shifting beacon contents around
when the TIM grows/shrinks
This will require a full rebuild of net80211 related programs -
ifconfig, hostapd, wpa_supplicant.
This takes the usual shortcut of only sandboxing the last input file.
It's a first cut and this program will be easy to adapt to sandbox all
files in the future.
iconv(1) has been changed to only open the conversion descriptor once,
since the input and output encodings are fixed over all inputs.
Instead, the descriptor is simply reset after each use (documented in
iconv(3) API).

For now, only enter the sandbox for the last file processed (including
stdin for zero-argument mode).
Sandboxing all inputs will require a little restructuring of the
program.

We restrict the (optional) input file and output files. It would be
nice to restrict the KVM files, but that's up to libkvm.
We wait until after kvm_nlist() is invoked to cap_enter() because
kldsym() isn't supported in the Capsicum sandbox.

Separate dataset opening from reading/parsing. The number of input
files is already capped to a small number, so just open all input files
before sandboxing.

This is a direct port of the kernel %b format.
I'm unclear on if (more) non-portable printf extensions will be a
problem. I think it's desirable to have userspace formats include all
kernel formats, but there may be competing goals I'm not aware of.

ioctl/fcntl arrays for their root fd for relative opens, consolidate in the
