* Get a summary for a message.

* If the name should not be displayed, the element is NULL.

* - dc_lot_t::text2: contains an excerpt of the message text.
* - dc_lot_t::timestamp: the timestamp of the message.
* - dc_lot_t::state: The state of the message as one of the DC_STATE_* constants (see #dc_msg_get_state()).
*
* Typically used to display a search result. See also dc_chatlist_get_summary() to display a list of chats.
