4Subject: [PATCH] sd-bus: make BUS_DEFAULT_TIMEOUT configurable
5
6This adds sd_bus_{get,set}_method_call_timeout().
7If the timeout is not set or set to 0, then the timeout value is
8parsed from $SYSTEMD_BUS_TIMEOUT= environment variable. If the
9environment variable is not set, then built-in timeout is used.
