Add a routine to Wiretap that takes a file type value and an

encapsulation value and returns a GArray containing all the file types
that could be used to save a file of that file type and that
encapsulation value (which could be WTAP_ENCAP_PER_PACKET), with the
input file type first if that can be used and pcap or pcap-ng first if
not and if one of them can be used, and with pcap and pcap-ng clustered
together if they're among the file types that can be used.

Use that routine for the GTK+ file save dialog.
