Subject: [PATCH] Bug 18562: Add koha-sip maintenance script

This patch introduces a single script to handle all actions on SIP
servers for Koha instances. It is intended to be a replacement for:

- koha-start-sip
- koha-stop-sip
- koha-enable-sip

It adds a function called is_sip_running to koha-functions.sh.

To test:
- Apply this patch
- Run:
  $ misc4dev/cp_debian_files.pl
  $ sudo koha-sip --enable kohadev
  $ sudo koha-sip --start kohadev
  $ sudo koha-sip --status kohadev
=> SUCCESS: The SIP server is running for kohadev
- Run:
  $ sudo koha-sip --restart --verbose kohadev
  $ sudo koha-sip --status kohadev
=> SUCCESS: The SIP server is running for kohadev
- Run:
  $ sudo koha-sip --stop kohadev
  $ sudo koha-sip --status kohadev
=> SUCCESS: The SIP server is not running for kohadev
- Play with other combinations like enabling an already enabled
instance, etc. Remember you need to remove the
/etc/koha/sites/kohadev/SIPconfig.xml file so it is considered disabled.
