bug#22576: 25.0.90; url-queue does not have guaranteed progress

[Lars Ingebrigtsen]

If a host doesn't respond, the callbacks from `url-retrieve' will never
be called.  There should therefore be some sort if mechanism to abort
things that take a long time to complete.  Either a timer of some sort,
or a timeout in url-retrieve.  The latter would be preferable.
