The -Wimplicit-fallthrough=3 warning is quite flexible of accepting
a fall-through warning.
Some comments were missing or not detected correctly.
Thereby, also change all other comments to follow the exact
same pattern.
nm_spawn_process() only sets error if the g_spawn_sync() itself fails,
not when the program ran returns a non-zero code.

update_dns() is rather complicated. The part where we collect
resolv-conf data can be moved out. That is nice, because
_collect_resolv_conf_data() has no side-effects (except logging)
and it's only purpose is to return the out-arguments.
It is useful to let clients retrieve the current DNS configuration,
which can be displayed to users or used (together with dns=none) to
implement custom DNS configuration logic through external tools.
Extend the D-Bus API and introduce a new NMDnsManager interface that
contains all the information related to DNS configuration.
At the moment the new DnsManager object only contains basic properties
describing the current DNS mode and resolv.conf manager.
Previously we printed the DNS configuration for all devices including
unmanaged and unconfigured ones:
dns-mgr: config: 100 best v4 ens3 : 192.168.10.1
dns-mgr: config: 100 default v6 ens3 : fd01🔡:3681:c4ff:fec0:fe94
dns-mgr: config: 100 default v4 lo :
dns-mgr: config: 100 default v6 lo :
dns-mgr: config: 100 default v4 ens9 :
dns-mgr: config: 100 default v6 ens9 :
Instead, print only devices that have name servers set.
A new DNS may have different data for us. So tell dnsmasq to
automatically clear the cache when servers change.

Keep the include paths clean and separate. We use directories to group source
files together. That makes sense (I guess), but then we should use this
grouping also when including files. Thus require to #include files with their
path relative to "src/".
Also, we build various artifacts from the "src/" tree. Instead of having
individual CFLAGS for each artifact in Makefile.am, the CFLAGS should be
unified. Previously, the CFLAGS for each artifact differ and are inconsistent
in which paths they add to the search path. Fix the inconsistency by just
don't add the paths at all.
