Update beacon handling to sync w/ vap code base:

o add driver callback to handle notification of beacon changes;
  this is required for devices that manage beacon frames themselves
  (devices must override the default handler which does nothing)
o move beacon update-related flags from ieee80211com to the beacon
  offsets storage (or handle however a driver wants)
o expand beacon offsets structure with members needed for 11h/dfs
  and appie's
o change calling convention for ieee80211_beacon_alloc and
  ieee80211_beacon_update
o add overlapping bss support for 11g; requires driver to pass
  beacon frames from overlapping bss up to net80211 which is not
  presently done by any driver
o move HT beacon contents update to a routine in the HT code area
