Subject: [PATCH] Fix the zombie process of ibus-gconf when ibus-daemon
restarts.
- Fix the typo in bus_dbus_impl_destroy() (dbusimpl.c)
- Modify bus_server_run() and _ibus_exit() (ibusimpl.c, server.c)
bus_ibus_impl_destroy() needs to be called so that waitpid()
prevents processes from becoming zombie.
- Change the declaration of bus_server_quit(). (server.h)
BUG=redhat#697471
