fix broken squid configuration

(traffic shaper) add support for address lists, and invert src/dst. closes https://github.com/opnsense/core/issues/1226

(mvc, model) add support for lists of networks/addresses in NetworkField, requirement for https://github.com/opnsense/core/issues/1226

(BaseModel) Always log the class where validation failed

(IDS) extend support for compressed files with "inline::" keyword to be able to download parts of an archive (required to download snort rules).
Change processing order to always stream data to tempfiles first, so we can reuse downloaded files (an archive scan isn't very expensive)

This reverts commit 5e1bb856.

We don't know the ultimate performance penalty of using plugins
for every component, so for now keep core functionality in
services.inc.

(services.inc / services_radvd_configure) more duplication for https://github.com/opnsense/core/issues/1196

(services.inc / services_radvd_configure) fix for https://github.com/opnsense/core/issues/1196 and cleanups

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)

(services) add support for "non stoppable" services, configuration options without status. needed for https://github.com/opnsense/core/issues/1217

Add translatable template

While there, kill "if (write_config())" constructs as this
really isn't a thing.

Not sure if this works, but it looks better than before.

This doesn't do anything in particular, because we don't know
what the input is without parsing it further.  It's not worse
than before in any case.  ;)
