EN-WEU WU 93c6906e36 wtap(4): implement monitor mode and handle radiotap ...

Implement monitor mode by simply adding IEEE80211_C_MONITOR to ic->ic_cap.

To get additional informations when capturing 802.11 frames, radiotap is
 inserted by wtap_tx_tap() when TX and wtap_rx_tap() when RX.

There are some type faults in struct wtap_rx_radiotap_header which are
 mainly mistakenly store unsigned values into signed integers.
I have fixed them (wtap(4)) by complying with the types defined
 in https://www.radiotap.org/fields/defined.

Becuase the struct wtap_rx_radiotap_header comes from ath(4),
there may be another patch to fix the type faults in ath(4).
