[PATCH V3] libxenstore: filter watch events in libxenstore when we unwatch
...be handled before event B.
So on next xs_watch_read the user could retrieve an unwatch token and
a segfault occured if the token store the pointer of the structure
(ie: "backend:0xcafe").
To avoid problem with previous application using libXenStore, this behaviour
will only be enabled if XS_UNWATCH_SAFE is give to xs_open.

[PATCH V2] libxenstore: filter watch events in libxenstore when we unwatch
While on entry to xs_unwatch, there may be an event on its way from
xenstored (eg in the ring or in the local kernel), all such events
will definitely come before the reply to the unwatch command. So at
the point where the unwatch reply has been processed (after xs_talkv),
any such now-deleted watch events will definitely have made it to
libxenstore''s queue where we can remove them.
