Implementation of SPNEGO authentication for Hunchentoot

Monitors hunchentoot connections and logs the connections stuck in the same state for a long time (due to slow or inactive clients and network stream timeouts that hunchentoot tries to utilize not working properly). Offers an option to shutdown the stuck connections sockets manually or automatically, thus unblocking the connection threads and preventing thread and socket leak. See https://github.com/edicl/hunchentoot/issues/189
