If the purpose of this is simply to allow the guest to discard all its
watches, I think a new xenstore command is a better plan than this

In particular, previously, only dom0 was allowed to use INTRODUCE.

I'm not convinced that we have fully throught through the implications
of allowing guests to do it under some circumstances, and I can see no
reason for trying to think about those implications when allowing a
guest to delete all its watches would be straightforward.
