Extend the existing url_to_path() to take the URL string and then use
that to simplify the snapshot/restore code paths.

In order to maintain correct time when doing pause/resume and
snapshot/restore operations, this patch stores the clock value
on pause, and restore it on resume. Because snapshot/restore
expects a VM to be paused before the snapshot and paused after
the restore, this covers the migration use case too.
