patch to handle vendor extension part
Build Information:
Paste the COMPLETE build information from "Help->About Wireshark", "wireshark
-v", or "tshark -v".

Radiotap header had defined an extension bit to allow further enhancements, but
the current dissector cannot handle more than one it_present word.
Vendor extension had been proposed in the following link
http://www.radiotap.org/Discussion/Vendor-Extensions
as bit 30.
This patch is to allow vendors use this bit and add one more it_present word to
define their own fields. This is a very simple patch to add a place holder for
that (but not try to interpret) so that a packet with vendor's extended
radiotap header doesn't break the dissector. Further enhancement can be done to
allow multiple vendor extensions.
