rh#1588900

The Eclipse Mosquitto broker up to version 1.4.15 does not reject strings that
are not valid UTF-8. A malicious client could cause other clients that do reject
invalid UTF-8 strings to disconnect themselves from the broker by sending a
topic string which is not valid UTF-8, and so cause a denial of service for the
clients.
