Subject: [PATCH] Add --with-idle-exit-timeout configure option

The option enables setting IdleExitTimeout to a desired value - f.e.
setting to zero will disable automatic shutdown, which is useful on servers,
where cupsd is expected to run even if there is no web interface, no jobs
and CUPS doesn't share queues.
