Preconfigure allowed_hosts.conf style files for plugins

set the variable vdr_allowed_hosts (must be a list of IPs/IP ranges) to preconfigure all host-
or ip-range based access options.

At the moment this applies to:
 - svdrphosts.conf
 - xineliboutput's allowed_hosts.conf (and the plugin's ARGSDIR configuration file)
 - vnsiserver's allowed_hosts.conf
 - streamdev-server's streamdevhosts.conf

It is possible to override host settings for individual services by
setting up extra lists for the following variables:
 - vdr_svdrphosts
 - xineliboutput_allowed_hosts
 - vnsiserver_allowed_hosts
 - streamdev_server_allowed_hosts
