* bus/config-parser-trivial.h:
Add a security sensitive stripped down config parser for the setuid
launcher. This file only reads what it needs, and doesn't try to do
anything remotely clever like including external files.
It is not intended to validate the config file; it is expected that
config-parser will do that before the setuid program tries to read it.
