* bus/config-parser-common.c:
(bus_config_parser_element_name_to_type),
(bus_config_parser_element_type_to_name):
* bus/config-parser-common.h:
We don't want to run the whole config parser with all it's deps in the
setuid program. We need to implement a stripped down config parser just
for the launcher, and to do so I need some common functions and
defines; add them here.
