SeongJae Park 3dc86ca6b4 xen/xenbus: Count pending messages for each watch
This commit adds a counter of pending messages for each watch in the
struct.  It is used to skip unnecessary pending messages lookup in
'unregister_xenbus_watch()'.  It could also be used in 'will_handle'
callback.

This is part of XSA-349
