One more step in privilege separation.

Add a capture_interface_list(), which works similar to
get_interface_list() except that it forks dumpcap instead of calling
the pcap routines directly.  Use it in the GUI.

Add a "-I" flag to dumpcap, which prints out verbose interface
information.

Tested under Windows and Linux.
