* pay attention to all folders, but IMAP can only pay attention to
* one folder at a time.) But it doesn't have any way to know when
* it's lying, so it's only safe to call it when you know for sure
* that the store is paying attention to the folder, such as when it's
* just been created, or you get a folder_changed or message_changed
* signal on it.
*
* camel_store_get_folder_info() always gives correct answers for the
* folders it checks, but it can also return -1 for a folder, meaning
* it didn't check, and so you should stick with your previous answer.
*
* update_1folder is called from three places: with info != NULL when
* the folder is created (or get_folder_info), with info == NULL when
* a folder changed event is emitted.
*
* So if info is NULL, camel_folder_unread_message_count is correct,
* and if it's not NULL and its unread_message_count isn't -1, then
* it's correct. */
