Message:

• Remove trace_get_wireless_fcs as it is no longer part of the Radiotap standard.
• Update trace_get_wire_length to account for the presence (or absence) of FCS bytes at the end of wireless frames. (only pcap and pcapfile for now)
• Update radiotap libpacketdump decoder to no longer output non-standard FCS field.
• Update test-wireless to ensure new length functions work correctly.
