As mentioned by zioproto[1] 6and4 is badly broken, this patch will
use 2 different configuration and init scripts.

olsrd: configuration sanity checks

* do not start in presence of the old /etc/config/olsrd
* use always use the appropriate IpVersion.
olsrd: avoid fake startup-error messages

Calling service_check too early may result in a false reading
olsrd: hotplug script works for IPv4 and IPv6

This should fix issue #16
hnetd: add global config file
batman-adv: upgrade package to latest release 2014.2.0
