net: if_media for 1000Base-BX BiDi

1000Base-BX uses two wavelengths, commonly 1310nm, 1490nm, 1550nm, or
1590nm, in a Coarse Wavelength Division Multiplexing (CWDM) arrangement
so that a single fiber strand may carry both upstream and downstream.
It is sometimes referred to as BiDi for bi-directional usage of one
fiber.

Optics must be paired such that the RX and TX wavelengths cross over,
with one side often called U(pstream) and the other D(ownstream).

This technology is useful for increasing link density or working around
construction issues, and is also frequently used as a last mile delivery
technology for FTTx.

sys: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.

[net80211] start laying down the foundation for 11ac support.

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.
