Fix bug http://bugs.wireshark.org/bugzilla/show_bug.cgi?id=1757 :
Try to call get_interface_descriptive_name() as little as possible (storing
the result in capture_opts) to avoid a performance hit during live capture
(especially if you have lots of interfaces) and to avoid leaking memory.
One issue with this is that capture_opts.c cannot (without adding significant
dependencies) set the iface_descr so readers of that field (only gtk/main.c
and tshark.c) use a macro to (set if not already set and) get the value of
that field.
