One word for a route that is not taken: rejected

The API, the metrics, the status page and the documentation say a route
is "rejected" (/api/routes/rejected, rejected_routes,
bgp_routes_rejected_total, "Rejected routes"), and the reason type is
Rejection. The code that keeps the record said "refused": RefusalLog,
PeerRefusals, RefusedRoute, RefusalsView, RefusedRouteView, the refusals
module. Those are RejectionLog, PeerRejections, RejectedRoute,
RejectionsView, RejectedRouteView and rejections now, and the log line
says "Rejected a route". Nothing the API or the metrics expose changes.

Refusing stays what it was: a connection turned away at the door
(server::Refusal), a kernel that would not take a route, an OPEN we
would not have.

The two aliases of SendReceive, AddPathSendRecv and OrfSendRecv, are
gone; it is one type.
