The z39.50 responder has a number of command line options that are not
accessible if using the debian scripts to control it. We should be able
to set those options in the koha conf file to be passed to the script
1) Apply this patch
2) Copy your kohaclone's koha-z3950-responder to /usr/sbin/koha-z3950-responder
3) Add "<z3950_responder_options>--add-item-status k</z3950_responder_options>"
inside your <config> block in your koha-conf.xml file
4) Use koha-z3950-responder to start/restart the z39.50 responder, note the
item status is now in subfield k!
There needs to be a check before doing the xmlstarlet here, as the responder
won't start if the config option doesn't exist in koha-conf.xml. This will be a
problem for upgrading libraries who don't yet have the config options.
