When `setWgengineStatus` is invoked concurrently from multiple goroutines, it is possible that the call invoked with a newer status is processed before a call with an older status. e.g. a status that has endpoints might be followed by a status without endpoints. This causes unnecessary work in the engine and can result in packet loss. This patch adds an `AsOf time.Time` field to the status to specifiy when the status was calculated, which later allows `setWgengineStatus` to ignore any status messages it receives that are older than the one it has already processed.
