    Make value_set_missing(), etc. tolerate values of width -1.
    
    In some circumstances a value of width -1 crops up, e.g. when a case is
    made from a dictionary that has had a variable deleted in the middle.
    Such a value has no content at all.  In the long run it should be possible
    to get rid of these values entirely--their presence is a wart--but for now
    the case and value code needs to tolerate them.
    
    This fixes a segfault in the GUI when inserting a new case when the
    datasheet case has a column with width -1 (due to deletion of a variable),
    which was caused by case_set_missing() calling value_set_missing() for
    the -1 width variable, which in turn was writing through an invalid
    pointer.
