This is a bugfix release: * Only send a single DISCONNECT command when using -l in the pub client. * Set QoS=1 on PUBREL commands to meet protocol spec. * Don't leak sockets on connection failure in the library. * Install man pages when building under cmake. * Fix crash bug on malformed CONNECT message. * Clients are now rejected if their socket peer name cannot be obtained on connection. * Fix a number of potential problems caused when a client with a duplicate id connects. * Install mosquitto.conf under cmake.
