This improves the HTML rendering.
But it also causes a lot of non-resolvable linkends warning when rendering a
separate manual pages into roff/mman. The messages are harmless, but still
a bit ugly.
The logging domain VPN_PLUGIN controlls logging of the VPN plugins.
Especially at verbose levels <debug> and <trace>, the plugins might
reveal sensitive information in the logging.
Thus, this level should not be enabled by a
$ nmcli logging general level DEBUG domains ALL
It should only be enabled when requested explicitly.
$ nmcli logging general level DEBUG domains ALL,VPN_PLUGIN:DEBUG
Previously, the special level VPN_PLUGIN was entirely excluded from
ALL and DEFAULT domains and it was entirely disabled by default. That
is however to strict, as it completely silences the VPN plugins by
defult. Now, enable them by default up to level INFO.
VPN plugins should take care that they don't reveal sensitive
information at levels <info> (LOG_NOTICE) and higher (less verbose).
For more verbose levels they may print passwords, but that should
still be avoided as far as possible.
Until before 1.2.0, NetworkManager would always write resolv.conf as file, but
if /etc/resolv.conf was a symlink, it would follow the link instead of
replacing it with a file ([1], [2]).
With 1.2.0, we initially dropped that behavior and added a new 'rc-manager=none'
which writes resolv.conf to /var/run/NetworkManager and symlinks resolv.conf [3].
In case resolv.conf being already a symlink to another target, it would
not be replaced [4].
Later, we added 'rc-manager=file', which always writes /etc/resolv.conf as
file [5].
With 1.4.0, we will rename 'rc-manager=none' to 'rc-manager=symlink' [6].
This commit now fixes 'rc-manager=file' to restores the pre-1.2 behavior
and follow symlinks.

Support 3 new flags for Reload:
- 0x01 (CONF): reload the configuration from disk
- 0x02 (DNS_RC): write DNS configuration to resolv.conf
- 0x04 (DNS_FULL): restart DNS plugin
Omitting all flags is the same as reloading everything, thus SIGHUP.
This logging domain will be used to enable debugging of the VPN plugins.
However, the plugins might expose sensitive data in this mode, so exclude
the new domain from "LOGD_ALL".
Downstream might want to choose a different default value for
main.rc-manager setting (and it can does so, by compiling with
explicit resolvconf or netconfig support).
Make the default configurable at build-time and also embed it into
the manual page of "NetworkManager.conf".

The following settings are effectively identical:
dns=none,rc-manager=*any*
dns=none,rc-manager=unmanaged
dns=default,rc-manager=unmanaged
The new setting is only there for completeness and only
makes sense for a dns plugin.
We already have "rc-manager=file", rename "rc-manager=none" to "symlink"
because that better describes what it is actually doing. Of course, the
old name is still accepted.
The script is called synchronously from NetworkManager so it can handle
asynchronicity itself. The long-term plan is to incorporate the script
partially into the new plugin and partially into a dnssec-trigger
library which will be used instead of dnssec-trigger daemon.

Interpret the configuration option main.debug and the
environment variable NM_DEBUG as a comma separated list
of debugging options (parsed with g_parse_debug_string()).
Currently only the option "RLIMIT_CORE" is supported, to set
the core dump size to unlimited.

The [main] section is not mandatory.
Clarify in several places that the keyfile plugin is always used for
fallback, and that the [keyfile] section is normally only used if you
aren't using any other plugin.
Fix some erroneous references to "keyfile" and "ifdown" in the
ifupdown section.
Update the ifcfg-rh docs to list all currently-supported connection
types.
Swap the order of ifcfg-suse and ifupdown to make them alphabetical.
(Note that ifnet is currently missing.)

The previous ignore-carrier rules did not work well with dynamic IP
(dhcp/slaac) connections. Change the rule so that only static IP
connections can be activated when carrier is not present (but both
static and dynamic connections will remain up when carrier is lost).
Add a "monitor-connection-files" config option, which can be set to
"false" to disable automatic reloading of connections on file change.
To go with this, add a new ReloadConnections method on
o.fd.NM.Settings that can be used to manually reload connections, and
add an nm-cli command to call it.
DocBook is not my favorite thing in the world, but it's
<lots-of-emphasis>far</lots-of-emphasis> saner than troff. Some style
parts cribbed from systemd.
This is preparatory work for actually improving the content of the
man pages.
