[PATCH v4 02/17] tools/xenstore: remove all watches when a domain has stopped

[Juergen Gross <jgross@xxxxxxxx>]

When a domain has been released by Xen tools, remove all its
registered watches. This avoids sending watch events to the dead domain
when all the nodes related to it are being removed by the Xen tools.
