(cherry picked from commit 504c947b)

(ipsec) fix syslog output, eventually we should switch to the new style loggers, but for now it's better to make sure charondebug is respected.

From the docs:

Starting with version 4.2.9, strongSwan provides a much more flexible configuration of the loggers. Logger configurations in strongswan.conf have a higher priority than charondebug in ipsec.conf: If you define any loggers in strongswan.conf, charondebug does not have any effect at all.

(crashreport) something seems to trigger Phalcon\Mvc\View->render() before initialize() was called, not sure what it is, probably something changed in phalcon to trigger this in some cases.

Quite some inconsistencies in this function, parameters that can't be set, lack of logic and code duplication.

* removes get_configured_pppoe_server_interfaces(), which can't work anyway... pppoe server interfaces are registered via the plugin itself.
* $dhcpv6ifconf['mode'] can't be set anywhere....
* don't try to revalidate rainterface
* collect "real interface" from dhcpif, shouldn't use carp if
* remove code duplication in dns collection
* move checks up for interface we should skip (when possible)
* RA subnets do not have any backend ties

Some minor tweaks in the file, e.g. we shouldn't use gettext()
for most tings, don't need translations in config files or for
strings that are hardly translatable (OpenVPN).
