        * Bumped to version 2.0.8

        * lib/dispatch.c: locking cleanup (2.1 backport)        

        * lib/conntrack.c: (z_conntrack_add_stream,
        z_conntrack_remove_stream): added a mutex protecting the
        connection_poll as it was accessed from multiple threads,
        (z_conntrack_socket_free): fixed a memory leak in ZCTSockets, the
        ZSockAddr members were not freed,
        (z_conntrack_socket_ref, z_conntrack_socket_unref): use a lock to
        protect the reference counter,
        (various functions): ZPacket does not use reference counts any
        more (to avoid the need to lock)
        (z_conntrack_socket_start, z_conntrack_socket_shutdown):
        add/remove a reference to the referenced structure to avoid
        freeing ZCTSockets which were not shut down
        (z_conntrack_packet_in): backported runtime session_limit, added
        log messages about new sessions (2.1 backport)

        * lib/pydispatch.c: added support for session_limit (2.1 backport)

        * lib/packstream.c: adapted to refcountless ZPackets (2.1 backport)

        * lib/packet.c: dropped reference counting as it would require a
        lock on the ref_count field (2.1 backport)

        * lib/dispatch.c (z_dispatch_connection): lock the chain while
        traversing it,
        (z_dispatch_register): upgrade to write lock earlier to avoid
        parallel binding to the same port, handle races by looking up the
        hashtable again when the write lock is acquired (2.1 backport)

        * lib/attach.c: set the bound address in the ZConnection structure
        to let the proxy use it in its log messages
