[Koha-patches] [PATCH] Bug 10624: 'status' option switch for the packages init script

[Tomas Cohen Arazi]

This patch makes the init script return the status of the relevant processes.
It relies on the koha-list switches added by 10622, and is written on top of the patch from 10617 that cleaned the init script.

To test:
- Apply the patch (+ 10622 so the SIP part works), build package and install
- Run
 $ service koha-common status

Note: it can be tested just copying the debian/koha-common.init script to a server running koha-common instances and calling it
 $ ./koha-common.init status

If you don't have a patched koha-list command it will fail to report SIP servers status.

Regards
To+

Edit: added the PID parameter to daemon as it failed to check SIP servers were running otherwise.
