    Fix crash in UDP Multicast Streams dialog
    
    Attempting to open the UDP Multicast Streams dialog in the GTK UI
    triggers an instant crash (heap-buffer-overflow).
    
    Déjà vu. This is the same problem that plagued the RTP Streams dialog.
    This patch is based on the fix in v1.99.3rc0-33-g2c65b33
    (mcaststream_dlg_update confused GList vs. mcaststream_tapinfo_t).
    
    After fixing that, the dialog crashed shortly after setting parameters
    (heap-use-after-free). That fix is based on v1.99.10rc0-292-gb02a0ee
    (after a retap, the old items were still present in the list).
    
    Just that change was not enough as clearing the list still triggered a
    signal, possibly because of the "changed" signal (while the RTP player
    uses a selection setter function). Apply the patch based on
    v1.99.10rc0-270-g01bd832 (disable selection while clearing).
