Please backport lxc 1.1.5-0ubuntu1 (main) from xenial

Please backport lxc 1.1.5-0ubuntu1 (main) from xenial to trusty.

Reason for the backport:
========================
Updating the backport to the current version from Xenial.

The same version is being pushed as SRUs to both vivid and wily, so not
concern about updates there.

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 xenial -d trusty lxc

* trusty:
[x] Package builds without modification
[x] lxc-dbgsym installs cleanly and runs
[x] lxc-templates-dbgsym installs cleanly and runs
[x] lxc-dbg installs cleanly and runs
[x] liblxc1 installs cleanly and runs
[x] lua-lxc installs cleanly and runs
[x] lxc-templates installs cleanly and runs

[x] python3-lxc installs cleanly and runs
[x] lxc-tests installs cleanly and runs
[x] liblxc1-dbgsym installs cleanly and runs
[x] lua-lxc-dbgsym installs cleanly and runs

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