NetBSD support for multiple data link types on an interface, from David

Young <dyoung@ojctech.com>, with some minor changes by Jason R. Thorpe
<thorpej@netbsd.org>, and further changes by me to:

	use "-y" rather than "-D" to set the link type ("-D" was already
	taken);

	use libpcap APIs to map between data link type names and values;

	supply stub versions of missing-but-needed libpcap APIs.

Update Jason Thorpe's e-mail address (Zembu is going away, if it hasn't
done so already).
