defbfbd185 DOS: use-after-free in ACL message handling 
Removing the last message in queue because of an ACL leaves last_msg
in a corrupted state. Therefore an unauthorized attacker may cause a
segfault of the broker.

eb514c9707 [487178] Obey mount_point when publishing wills. 
Wills published by clients connected to a listener with mount_point defined
now correctly obey the mount point. This was a potential security risk
because it allowed clients to publish messages outside of their restricted
mount point. This is only affects brokers where the mount_point option is in
use.

Thanks to Lance Riley.

cdbe62c2bb Outgoing messages with QoS>0 are no longer retried after a timeout. 
This change in behaviour can be justified by considering when the
timeout may have occurred.

* If a connection is unreliable and has dropped, but without one end
  noticing, the messages will be retried on reconnection. Sending
  additional PUBLISH or PUBREL would not have changed anything.

* If a client is overloaded/unable to respond/has a slow connection then
  sending additional PUBLISH or PUBREL would not help the client catch
  up. Once the backlog has cleared the client will respond. If it is not
  able to catch up, sending additional duplicates would not help either.
