o Add the `set mode' command for change a links current mode. It

  is not possible to switch to or from dedicated or direct mode,
  but all other combinations are ok (eg. -auto -> -ddial).
o Cope with the fact that commands with optional context may not
  be able to obtain a link with command_ChooseLink() (if all links
  have been deleted for example).
o Allow `clone'ing in non-multilink mode.  We may for example want
  to configure two links in unilink mode and dial them both, using
  the one that comes up first.  It's also possible to rename
  ``deflink'' by cloning it, deleting the original, then setting
  the mode of the new link.
