    Fix #84: motifd is 64-bit app.
    
    Merge Richard Kreuter's clm-oids branch to master.  This allows
    motifd to work even if motifd is a 64-bit app.  From Richard:
    
    ...the server passes out 32-bits of a pointer as external IDs for
    instances of a handful of types [1]. On a 64-bit machine, the instances'
    addresses might not fit in a 32-bit address, though.
    
    (In fact, on my FreeBSD/amd64 machine, when I run the example from the
    documentation, the first shell widget always gets created at
    create the second widget with the shell as parent crashes the server.)
    
    Seems like there are two options:
    
    A. Change the wire protocol to accomodate 64-bit integers.
    
    B. Synthesize 32-bit identifiers for instances of the offending types.
    
    Option B seems simpler....
    
    [It] suffices to run the example in the doc and the programs in
    INTERFACE.... Obvious problems in the current code:
    
    1. It's a doubly linked alist associating pointers with 32-bit integers.
    
    2. It looks like nothing ever gets removed from the alist....
    
    3. I'm not certain that I've caught all the places where motifd hands
       out pointers to Lisp.
    
    [1] I think the complete list is AcceleratorTable, Atom, FontList,
    TranslationTable, Widget, and sometimes XmString.
