In tools/xenstore there are living xenstored and xenstore clients. They are no longer sharing anything apart from the "xenstore" in their names. Move the xenstored sources into a new directory tools/xenstored while dropping the "xenstored_" prefix from their names. This will make it clearer that xenstore clients and xenstored are independent from each other. In order to avoid two very similar named directories below tools, rename tools/xenstore to tools/xs-clients. Drop the make targets [un]install-clients as those are not used in the Xen tree.
