Subject: [PATCH] Remove unused functions
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

After 95ee490bbdb97ab2b4f1dfa63a0a26e0dd1c2f17 they are not in public
API and are not used throughout the lxc codebase.
This has a bonus of removing workaround for bionic.
