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.

If the socket pair is still opened on reconnect, close it before
creating it again (just like the state variables). Otherwise, these
sockets are leaked on multiple mosquitto_connect() calls.
