Don't throw an exception in the notification handler if we're shutting down

OCaml calls WSACleanup in an at_exit handler. If we try to send a
notification after that we get an error and throw an exception in the
signal handler. This causes a segfault.

Fixes #59.
Initialise notification byte

Avoids memory checker warning (drmemory) about reading an uninitialised
byte.

Add a ?fd argument to Lwt_io.{open_connection,with_connection,establish_server}.

The rationale is that one might want to perform sockopts to the
sockets created by those functions. They should therefore not
internally create a file descriptor for their underlying socket
without presenting a way for the user to do sockopts on them. This
patch makes it possible to provide a fd to use instead of creating a
new one, fixing this issue without changing the current interface.
