Fabian Knittel 529b1ab288 client-connect: Add deferred support to the client-connect script handler
This patch introduces the concept of a return value file for the
client-connect handlers (this is very similar to the auth value file
used during deferred authentication).  The file name is stored in the
client_connect_state struct.

In addition, the patch also moves the storage of the client config file
name into struct client_connect_state.

Both changes are used by the client-connect script handler to support
deferred client-connection handling.  The deferred return value file
(deferred_ret_file) is passed to the script via the environment.

If the script succeeds and writes the value for deferral (2) into the
deferred_ret_file, the handler knows to indicate deferral.  Later on,
the deferred handler checks whether the value of the deferred_ret_file
has been updated to success or failure.
