Overhaul monitor mode handling:

Browse Source 
o replace DLT_IEEE802_11 support in net80211 with DLT_IEEE802_11_RADIO
  and remove explicit bpf support from wireless drivers; drivers now
  use ieee80211_radiotap_attach to setup shared data structures that
  hold the radiotap header for each packet tx/rx
o remove rx timestamp from the rx path; it was used only by the tdma support
  for debugging and was mostly useless due to it being 32-bits and mostly
  unavailable
o track DLT_IEEE80211_RADIO bpf attachments and maintain per-vap and
  per-com state when there are active taps
o track the number of monitor mode vaps
o use bpf tap and monitor mode vap state to decide when to collect radiotap
  state and dispatch frames; drivers no longer explicitly directly check
  bpf state or use bpf calls to tap frames
o handle radiotap state updates on channel change in net80211; drivers
  should not do this (unless they bypass net80211 which is almost always
  a mistake)
o update various drivers to be more consistent/correct in handling radiotap
o update ral to include TSF in radiotap'd frames
o add promisc mode callback to wi
