    rxgen: Generate default switch arm for void
    
    When defining an xdr union with a 'default' arm, rxgen generates xdr
    routines like this:
    
        bool_t
        xdr_myunion(...)
        {
            switch (objp->op) {
            case FOO:
                xdr_foo(...);
                break;
    
            default:
                xdr_default(...);
                break;
            }
        }
    
    However, if the default arm of the union is just 'void;', we just
    don't generate a 'default:' arm in the switch statment in the
    generated routines. If there are enum values that are not explicitly
    specified, and are handled by the default arm, this generates a
    compiler warning (which breaks the build for --enable-checking):
    
        foo_int.xdr.c:80:2 error: enumeration value 'BAR' not handled in switch [-Werror=switch]
        switch (objp->op) {
    
    To avoid this, change rxgen to always generate a 'default' arm in the
    generated switch if there's one specified in the RPC-L. For a void
    default, just generate an empty default arm, which avoids the compiler
    warning.
