[net80211] Add initial VHT support routines. This is a skeleton set based on ieee80211_ht.c. It implements some IE parsing, some basic unfinished negotiation, and channel promotion/demotion. However, by itself it's not enough to do VHT - notably, the actual channel promotion for STA mode at least is done in ieee80211_ht.c as part of htinfo_update_chw(). I was .. quite amused when I found that out. I'm checking this in so others can see progress rather than one huge commit when VHT is "done" (which will likely be quite a while.)

[net80211] Commit files missing in the previous commit These belong to my previous commit, but apparently I typed ieee80211_vhf.[ch] and forgot ht.h. Le oops.

[net80211] create a helper function to calculate the station facing VHT capabilities. This is needed for two reasons: * Drivers will need to know what the negotiated set of VHT capabilities and rates are in order to configure (and reconfigure for opmode/chanwidth changes) how to speak to a given peer; and * Because some vendors are "special", we should be careful in what we announce to them during peer association. This isn't the complete solution, as I still need to make sure that when sending out probe requests before we know what we want, we don't limit the capabilities being announced. This is important for IBSS/mesh work later on as probe request/response exchanges are the first hint at what a peer supports. I'll look at adding that to the API soon.
