Eventscripts - new function ctdb_check_args()

Pass this "$@" to do common eventscript argument checking.

For regular use putting this in 00.ctdb would be enough.  However, for
developer testing it can be useful to call this in other eventscripts.
For example, 10.interfaces and 13.per_ip_routing currently check these
by hand.
