 Very frequently we want to have a config type that is "int, restricted to
 some range of values".  We should have a means to represent that, and
 thereby save a bunch of boilerplate code.

 This could be done with new var_type_def_t for each range, but that could
 get out of hand.  Probably we want a way to add more info to the
 config_var_t.
