TG: attached are the following patches for GNUnet:

- 1: added GNUNET_i2s_full - full variant of GNUNET_i2s
- 2: GNUNET_CRYPTO_hash_from_string2 with additional length parameter,
     useful to prevent an additional strlen call when the caller already knows
     the length
- 3: custom mst callbacks for the server, enables using the server with a
     custom parser
- 4: added GNUNET_SERVER_client_set_finish_pending_write - enables changing the
     server behavior to finish pending writes when closing the connection
