Please backport keepalived 1:1.2.13-1 (main) from wily

Please backport keepalived 1:1.2.13-1 (main) from wily to trusty.

Reason for the backport:
========================
Backporting keepalived 1.2.13 from wily to trusty is needed to have support for unicast VRRP. This is critical as unicast mode is only supported for versions > 1.2.7.

Testing:
========
Mark off items in the checklist [X] as you test them, but please leave the checklist so that backporters can quickly evaluate the state of testing.

You can test-build the backport in your PPA with backportpackage:
$ backportpackage -u ppa:<lp username>/<ppa name> -s wily -d trusty keepalived

* trusty:
[X] Package builds without modification
[X] keepalived installs cleanly and runs

Reverse dependencies:
=====================
The following reverse-dependencies need to be tested against the new version of keepalived. For reverse-build-dependencies (-Indep), please test that the package still builds against the new keepalived. For reverse-dependencies, please test that the version of the package currently in the release still works with the new keepalived installed. Reverse- Recommends, Suggests, and Enhances don't need to be tested, and are listed for completeness-sake.
