Define four new radiotap fields per discussions with John Bicket, Sam

Browse Source 
Leffler, and others:

        IEEE80211_RADIOTAP_RX_FLAGS = 14,
        IEEE80211_RADIOTAP_TX_FLAGS = 15,
        IEEE80211_RADIOTAP_RTS_RETRIES = 16,
        IEEE80211_RADIOTAP_DATA_RETRIES = 17,

I describe the fields in the manual page and in comments in the
header file (cross-referenced by the manual page).
