* logic: by using BUS_ERROR_MAP_ELF_REGISTER, which however only

|
* works when linked into the same ELF module, or via
|
|
* sd_bus_error_add_map() which is the official, external API, that
|
|
* works from any module.
|
|
*
|
|
* Note that BUS_ERROR_MAP_ELF_REGISTER has to be used as decorator in
|
|
* the bus error table, and BUS_ERROR_MAP_ELF_USE has to be used at
|
|
* least once per compilation unit (i.e. per library), to ensure that
|
|
* the error map is really added to the final binary.
