/**
* Get a list of chats.
* The list can be filtered by query parameters.
*
* The list is already sorted and starts with the most recent chat in use.
* The sorting takes care of invalid sending dates, drafts and chats without messages.
* Clients should not try to re-sort the list as this would be an expensive action
* and would result in inconsistencies between clients.
*
* To get information about each entry, use eg. dc_chatlist_get_summary().
*
* By default, the function adds some special entries to the list.
* These special entries can be identified by the ID returned by dc_chatlist_get_chat_id():
* - DC_CHAT_ID_DEADDROP (1) - this special chat is present if there are
* messages from addresses that have no relationship to the configured account.
* The last of these messages is represented by DC_CHAT_ID_DEADDROP and you can retrieve details
* about it with dc_chatlist_get_msg_id(). Typically, the UI asks the user "Do you want to chat with NAME?"
* and offers the options "Yes" (call dc_create_chat_by_msg_id()), "Never" (call dc_block_contact())
* or "Not now".
* The UI can also offer a "Close" button that calls dc_marknoticed_contact() then.
* - DC_CHAT_ID_ARCHIVED_LINK (6) - this special chat is present if the user has
* archived _any_ chat using dc_archive_chat(). The UI should show a link as
* "Show archived chats", if the user clicks this item, the UI should show a
* list of all archived chats that can be created by this function hen using
* the DC_GCL_ARCHIVED_ONLY flag.
* - DC_CHAT_ID_ALLDONE_HINT (7) - this special chat is present
* if DC_GCL_ADD_ALLDONE_HINT is added to listflags
* and if there are only archived chats.
*
* @memberof dc_context_t
* @param context The context object as returned by dc_context_new()
* @param listflags A combination of flags:
* - if the flag DC_GCL_ARCHIVED_ONLY is set, only archived chats are returned.
* if DC_GCL_ARCHIVED_ONLY is not set, only unarchived chats are returned and
* the pseudo-chat DC_CHAT_ID_ARCHIVED_LINK is added if there are _any_ archived
* chats
* - if the flag DC_GCL_NO_SPECIALS is set, deaddrop and archive link are not added
* to the list (may be used eg. for selecting chats on forwarding, the flag is
* not needed when DC_GCL_ARCHIVED_ONLY is already set)
* - if the flag DC_GCL_ADD_ALLDONE_HINT is set, DC_CHAT_ID_ALLDONE_HINT
* is added as needed.
* @param query_str An optional query for filtering the list. Only chats matching this query
* are returned. Give NULL for no filtering.
* @param query_id An optional contact ID for filtering the list. Only chats including this contact ID
* are returned. Give 0 for no filtering.
* @return A chatlist as an dc_chatlist_t object.
* On errors, NULL is returned.
* Must be freed using dc_chatlist_unref() when no longer used.
*
* See also: dc_get_chat_msgs() to get the messages of a single chat.
