Subject: [PATCH] core: refuse to create wide-area record browsers when
wide-area is off
It fixes a bug where it was possible for unprivileged local users to
crash avahi-daemon (with wide-area disabled) by creating record browsers
with the AVAHI_LOOKUP_USE_WIDE_AREA flag set via D-Bus (either by calling
the RecordBrowserNew method directly or by creating hostname/address/service
resolvers/browsers that create those browsers internally themselves).
```
$ gdbus call --system --dest org.freedesktop.Avahi --object-path / --method org.freedesktop.Avahi.Server.ResolveHostName -- -1 -1 yo.local -1 1
Error: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying
```
```

wide-area has been disabled by default since
