Use cause vectors in src/patterns/{local,remote}-server.lisp
refs #565

src/patterns/local-server.lisp (call t local-method event): use
`event-id/opaque' to obtain a cause event id; add it to the reply
event
src/patterns/remote-server.lisp
(setf %method-listener :after t remote-method): use
`event-id/opaque' and cause mechanism instead of `event-id' and
meta-data mechanism to indicate associated request
(call t remote-method event): extract the first cause instead of a
meta-data item from the reply event; use `%event-id->key' to convert
event id to suitable keys
(%event-id->key): new function; helper function for converting event
ids to keys suitable for hash-table lookup
