[PATCH 2/5] Store daemon config pointer in the periodic watcher's private data

[Tyler Hicks <tyhicks@canonical.com>]

In preparation for moving the periodic watcher to auditd-listen.c,
periodic_handler() cannot rely on having access to the config global
variable. That can be solved by using the private data pointer built
into libev watchers.
