    Fix handling of invalid UAT items
    
    If the UAT file failed a field check, then the user_data pointer may be
    empty. As a result uat_save() triggers an invalid write.
    
    (Discovered while working with a dfilter_macros file having duplicate
    names for bug 10957, caught by ASAN.)
    
    The second issue fixed in this patch is that the validity of an item is
    only calculated when a new record is added. So even if the user edits
    the UAT and makes the entry valid, it would not be saved. This is solved
    by adding a new uat_update_record() function which got wires up into GTK
    and Qt.
    
    Some open-coded g_array_index and UAT[_USER]_INDEX_PTR are also
    converted.
