Brian Somers 880447787d Add a radius_Flush() function that waits for the response (or timeout) to
any pending RADIUS transaction.  Use this before sending RAD_STOP RADIUS
messages so that we definitely ``stop'' the session.

It was discovered that sometimes when the link timed out, we got lucky
enough to have an un-ACK'd RADIUS accounting transaction in progress,
resulting in the RAD_STOP message failing to send.
