IBSS-merge clean-up, inspired by some Linux patches from Jon Anderson (mail@janderson.ca): remove ieee80211_ibss_merge's TSFT argument. Do the TSFT comparison in the drivers (ath, atw). Remove a lot of extraneous debug statements from ieee80211_ibss_merge. Set the ieee80211_node's state to IEEE80211_STA_BSS after it's been copied to the ic_bss, not before. In struct ieee80211_node, make the ni_tstamp field a union of a uint64_t and the 8 TSF octets so that it's easier to compare a neighbor's TSF with the local TSF. Log IBSS merges (Greg Troxel's suggestion). Also log IBSS creation. These are rare and important events that deserve to be logged.

Define for more bits in the Service field of the 802.11 PLCP Header. For use by the subroutine ieee80211_compute_duration, add struct ieee80211_duration, and #define a number of microsecond constants used for the transmit timing of 802.11 packets. Add the subroutine ieee80211_compute_duration, which computes for any packet the appropriate 802.11 Duration field, the PLCP Length field, as well as the Duration and Length fields for an RTS frame. atw(4), rtw(4), future drivers, and possibly ath(4) will share ieee80211_compute_duration.

Fix a bug in ieee80211_compute_duration: the 802.11 Duration field in an 802.11 unicast data packet is equal to the duration of the SIFS and Acknowledgement. That is, the amount of time reserved *after* the packet has finished transmitting. Change the arguments to ieee80211_compute_duration: pass the entire packet length, not just the payload length. Add a 'debug' argument to ieee80211_compute_duration and its helper subroutine, ieee80211_compute_duration1. If debug != 0, ieee80211_compute_duration printfs its arguments and several local variables. In rtw(4), load the 802.11 Duration field with the result from ieee80211_compute_duration.
