* Try to activate the given service.
*
* connection is the connection requesting that the service be started,
* or NULL if the activation was caused by the dbus-daemon itself (when
* systemd activation waits for systemd to connect to us, or when calling
* SetEnvironment on systemd).
*
* auto_activation is TRUE if we are carrying out auto-starting (we are
* activating a service automatically in order to deliver a message to it)
* or FALSE if we are starting the service explicitly (as for
* StartServiceByName).
*
* activation_message is the message that caused this activation.
