/**
* Get a configuration option.
* The configuration option is set by dc_set_config() or by the library itself.
*
* Beside the options shown at dc_set_config(),
* this function can be used to query some global system values:
*
* - `sys.version` = get the version string eg. as `1.2.3` or as `1.2.3special4`
* - `sys.msgsize_max_recommended` = maximal recommended attachment size in bytes.
* All possible overheads are already subtracted and this value can be used eg. for direct comparison
* with the size of a file the user wants to attach. If an attachment is larger than this value,
* an error (no warning as it should be shown to the user) is logged but the attachment is sent anyway.
* - `sys.config_keys` = get a space-separated list of all config-keys available.
* The config-keys are the keys that can be passed to the parameter `key` of this function.
*
* @memberof dc_context_t
* @param context The context object as created by dc_context_new(). For querying system values, this can be NULL.
* @param key The key to query.
* @return Returns current value of "key", if "key" is unset, the default value is returned.
* The returned value must be free()'d, NULL is never returned.
