I've done target_create/destroy callbacks.

I'll try to see how to integrate target driver daemons to stgtd. For
that, ietd daemon needs to do all kernel-user space communication
through stgt netlink. Thus, we need to add some iSCSI specific
callbacks (like conn_create/destroy). Is it OK? Or is implementing
more generic message and callback(like STGT_UEVENT_SEND_MESSAGE) for
target driver specific tasks better?
