Bug#817669: sipsak: Removal of debhelper compat 4

[niels at thykier.net]

Source: sipsak
Severity: important
Usertags: compat-4-removal

Hi,

The package sipsak uses debhelper with a compat level of 4,
which is deprecated and scheduled for removal.

 * Please bump the debhelper compat at your earliest convenience.
   on the 15th of June.
   - Compat 9 is recommended
   - Compat 5 is the bare minimum
   - If the package has been relying on dh_install being lenient about
     missing files, please see "MIGRATING TO COMPAT 5 OR LATER" in [1].

 * Compat level 4 will be removed on the first debhelper upload after
   the 15th of June.

Thanks,
~Niels
