This patch adds/fixes the following:
- Ability to "merge" global configs from /etc/jail.conf
- Fixes the issue with depend when depends are in a separate jail.conf file
- All jails.conf jail (in /etc/jail.conf, /etc/jail.*.conf and /etc/jail.conf.d/*.conf) start automatically, without the need to define them in jail_list in rc.conf
