/**
* Import/export things.
* For this purpose, the function creates a job that is executed in the IMAP-thread then;
* this requires to call dc_perform_imap_jobs() regularly.
*
* What to do is defined by the _what_ parameter which may be one of the following:
*
* - **DC_IMEX_EXPORT_BACKUP** (11) - Export a backup to the directory given as `param1`.
* The backup contains all contacts, chats, images and other data and device independent settings.
* The backup does not contain device dependent settings as ringtones or LED notification settings.
* The name of the backup is typically `delta-chat.<day>.bak`, if more than one backup is create on a day,
* the format is `delta-chat.<day>-<number>.bak`
*
* - **DC_IMEX_IMPORT_BACKUP** (12) - `param1` is the file (not: directory) to import. The file is normally
* created by DC_IMEX_EXPORT_BACKUP and detected by dc_imex_has_backup(). Importing a backup
* is only possible as long as the context is not configured or used in another way.
*
* - **DC_IMEX_EXPORT_SELF_KEYS** (1) - Export all private keys and all public keys of the user to the
* directory given as `param1`. The default key is written to the files `public-key-default.asc`
* and `private-key-default.asc`, if there are more keys, they are written to files as
* `public-key-<id>.asc` and `private-key-<id>.asc`
*
* - **DC_IMEX_IMPORT_SELF_KEYS** (2) - Import private keys found in the directory given as `param1`.
* The last imported key is made the default keys unless its name contains the string `legacy`. Public keys are not imported.
*
* While dc_imex() returns immediately, the started job may take a while,
* you can stop it using dc_stop_ongoing_process(). During execution of the job,
* some events are sent out:
*
* - A number of #DC_EVENT_IMEX_PROGRESS events are sent and may be used to create
* a progress bar or stuff like that. Moreover, you'll be informed when the imex-job is done.
*
* - For each file written on export, the function sends #DC_EVENT_IMEX_FILE_WRITTEN
*
* Only one import-/export-progress can run at the same time.
* To cancel an import-/export-progress, use dc_stop_ongoing_process().
*
* @memberof dc_context_t
* @param context The context as created by dc_context_new().
* @param what One of the DC_IMEX_* constants.
* @param param1 Meaning depends on the DC_IMEX_* constants. If this parameter is a directory, it should not end with
* a slash (otherwise you'll get double slashes when receiving #DC_EVENT_IMEX_FILE_WRITTEN). Set to NULL if not used.
* @param param2 Meaning depends on the DC_IMEX_* constants. Set to NULL if not used.
* @return None.
