We always build PolicyKit support, because it merely depends on some
D-Bus calls. However, there are two things to configure:
- the default value for main.auth-polkit in NetworkManager.conf. This
is now called "-Dconfig_auth_polkit_default=$VAL".
- whether to install the policy file. This is called "-Dpolkit=$VAL".
These settings are mostly independent, so add "config_auth_polkit_default" to
make the default explicitly configurable.

The bluetooth plugin (with BlueZ5/NAP support) always gets
build, but DUN support requires a library.
When enabling build of the bluetooth subpackage, then always
enable DUN support. And enable it explicitly, especially meson
would not autodetect support and disable it by default.

The "ibft" plugin is no more. The default on RHEL/Fedora is now "ifcfg-rh[,keyfile]".
Adjust the configuration, because a wrong comment is confusing here.
Modifying configuration snippets is potentially annoying, because the user might
have edited the file, so on upgrade a "NetworkManager.conf.rpmnew" file
will be created. Still do it.

When opening a merge request from a fork of NetworkManager, then the
pipeline runs with the a checkout of the fork. That means, checkpatch
would compare the branch against "master" (or "nm-x-y" stable branches)
of the fork, instead of upstream.
That doesn't seem too useful. Instead, also add upstream NetworkManager
as git remote, fetch the branches, and use the branches from there as
base for checkpatch.

The preferred logo and logotype are the ones in the main "logo" folder.
There are also few variants available in the "alternate" folder that are
allowed.
Main color for the logo is blue #32557dff.
The alternatei logo red is #cc0000ff.
The font is Montserrat.

REQUIRED_PACKAGES has two uses:
- to setup a system for developing NetworkManager. This installs
convenience packages like "cscope".
- to install the packages required for unit testing in gitlab-ci.
For gitlab-ci we should only install the packages that we actually
need.
Previously, dnf/yum used to ignore packages that didn't exist.
In Fedora 32, dnf starts to fail the entire command:
No match for argument: python-gobject-base
Error: Unable to find a match: python-gobject-base
Since this script is supposed to work with different RHEL/Fedora
versions, it's expected that not all packages are available everywhere.
Fix that, by installing packages that we know that they might be missing
one by one (and ignore the error).
"NetworkManager-wifi" package requires either wpa_supplicant or iwd.
When installing the package without explicitly installing supplicant
or iwd (and not having it installed yet), then we want to drag in
wpa_supplicant by default. That is accomplished by suggesting wpa_supplicant
package.
Otherwise, the user installing NetworkManager-wifi might get iwd,
which is only functioning if the user explicitly enables the backend
in "NetworkManager.conf".

This is a one-off hacky tool that we'll use to convert the long license
boilerplates to SPDX headers that are more friendly to automated tools.
Then we can drop it and forget it existed.
Nowadays, we should prefer "/run" over "/var/run". When not specifying
during ./configure, autotools however still defaults to "/var/run".
This default is also visible in the pre-generated documenation, for
example `man NetworkManager.conf` says
Unless the symlink points to the internal file /run/NetworkManager/resolv.conf,
in which case the ...
Let's enable the option to use IWD as an alternative to wpa_supplicant
for Wi-Fi support. People have been asking for this, it works, and is well
maintained.
Completely rework how settings plugin handle connections and how
NMSettings tracks the list of connections.
Previously, settings plugins would return objects of (a subtype of) type
NMSettingsConnection. The NMSettingsConnection was tightly coupled with
the settings plugin. That has a lot of downsides.
Change that. When changing this basic relation how settings connections
are tracked, everything falls appart. That's why this is a huge change.
Also, since I have to largely rewrite the settings plugins, I also
added support for multiple keyfile directories, handle in-memory
connections only by keyfile plugin and (partly) use copy-on-write NMConnection
instances. I don't want to spend effort rewriting large parts while
preserving the old way, that anyway should change. E.g. while rewriting ifcfg-rh,
I don't want to let it handle in-memory connections because that's not right
long-term.

If the settings plugins themself create subtypes of NMSettingsConnection
instances, then a lot of knowledge about tracking connections moves
to the plugins.
Just try to follow the code what happend during nm_settings_add_connection().
Note how the logic is spread out:
- nm_settings_add_connection() calls plugin's add_connection()
- add_connection() creates a NMSettingsConnection subtype
- the plugin has to know that it's called during add-connection and
not emit NM_SETTINGS_PLUGIN_CONNECTION_ADDED signal
- NMSettings calls claim_connection() which hocks up the new
NMSettingsConnection instance and configures the instance
(like calling nm_settings_connection_added()).
This summary does not sound like a lot, but try to follow that code. The logic
is all over the place.
Instead, settings plugins should have a very simple API for adding, modifying,
deleting, loading and reloading connections. All the plugin does is to return a
NMSettingsStorage handle. The storage instance is a handle to identify a profile
in storage (e.g. a particular file). The settings plugin is free to subtype
NMSettingsStorage, but it's not necessary.
There are no more events raised, and the settings plugin implements the small
API in a straightforward manner.
NMSettings now drives all of this. Even NMSettingsConnection has now
very little concern about how it's tracked and delegates only to NMSettings.
This should make settings plugins simpler. Currently settings plugins
are so cumbersome to implement, that we avoid having them. It should not be
like that and it should be easy, beneficial and lightweight to create a new
settings plugin.
Note also how the settings plugins no longer care about duplicate UUIDs.
Duplicated UUIDs are a fact of life and NMSettings must handle them. No
need to overly concern settings plugins with that.
--
NMSettingsConnection is exposed directly on D-Bus (being a subtype of
NMDBusObject) but it was also a GObject type provided by the settings
plugin. Hence, it was not possible to migrate a profile from one plugin to
another.
However that would be useful when one profile does not support a
connection type (like ifcfg-rh not supporting VPN). Currently such
migration is not implemented except for migrating them to/from keyfile's
run directory. The problem is that migrating profiles in general is
complicated but in some cases it is important to do.
For example checkpoint rollback should recreate the profile in the right
settings plugin, not just add it to persistent storage. This is not yet
properly implemented.
--
Previously, both keyfile and ifcfg-rh plugin implemented in-memory (unsaved)
profiles, while ifupdown plugin cannot handle them. That meant duplication of code
and a ifupdown profile could not be modified or made unsaved.
This is now unified and only keyfile plugin handles in-memory profiles (bgo #744711).
Also, NMSettings is aware of such profiles and treats them specially.
In particular, NMSettings drives the migration between persistent and non-persistent
storage.
Note that a settings plugins may create truly generated, in-memory profiles.
The settings plugin is free to generate and persist the profiles in any way it
wishes. But the concept of "unsaved" profiles is now something explicitly handled
by keyfile plugin. Also, these "unsaved" keyfile profiles are persisted to file system
too, to the /run directory. This is great for two reasons: first of all, all
profiles from keyfile storage in fact have a backing file -- even the
unsaved ones. It also means you can create "unsaved" profiles in /run
and load them with `nmcli connection load`, meaning there is a file
based API for creating unsaved profiles.
The other advantage is that these profiles now survive restarting
NetworkManager. It's paramount that restarting the daemon is as
non-disruptive as possible. Persisting unsaved files to /run improves
here significantly.
--
In the past, NMSettingsConnection also implemented NMConnection interface.
That was already changed a while ago and instead users call now
nm_settings_connection_get_connection() to delegate to a
NMSimpleConnection. What however still happened was that the NMConnection
instance gets never swapped but instead the instance was modified with
nm_connection_replace_settings_from_connection(), clear-secrets, etc.
Change that and treat the NMConnection instance immutable. Instead of modifying
it, reference/clone a new instance. This changes that previously when somebody
wanted to keep a reference to an NMConnection, then the profile would be cloned.
Now, it is supposed to be safe to reference the instance directly and everybody
must ensure not to modify the instance. nmtst_connection_assert_unchanging()
should help with that.
The point is that the settings plugins may keep references to the
NMConnection instance, and so does the NMSettingsConnection. We want
to avoid cloning the instances as long as they are the same.
Likewise, the device's applied connection can now also be referenced
instead of cloning it. This is not yet done, and possibly there are
further improvements possible.
--
Also implement multiple keyfile directores /usr/lib, /etc, /run (rh #1674545,
bgo #772414).
It was always the case that multiple files could provide the same UUID
(both in case of keyfile and ifcfg-rh). For keyfile plugin, if a profile in
read-only storage in /usr/lib gets modified, then it gets actually stored in
/etc (or /run, if the profile is unsaved).
--
While at it, make /etc/network/interfaces profiles for ifupdown plugin reloadable.

This is inspired by the existing systemd integration, with a few differences:
* This parses the WPAD option, which systemd requested, but did not use.
* We hook into the DAD handling, only making use of the configured address
once DAD has completed successfully, and declining the lease if it fails.
There are still many areas of possible improvement. In particular, we need
to ensure the parsing of all options are compliant, as n-dhcp4 treats all
options as opaque, unlike sd-dhcp4. We probably also need to look at how
to handle failures and retries (in particular if we decline a lease).
We need to query the current MTU at client startu, as well as the hardware
broadcast address. Both these are provided by the kernel over netlink, so
it should simply be a matter of hooking that up with NM's netlink layer.

In continations (that use spaces for alignment), don't allow the number
of leading tabs to change. Previously only removal of tabs was
disallowed, but addition doesn't make sense either, as only spaces
should be used for further alignemnt.
This catches situations like this:
|<-tab->all_work_and_no_play (makes,
|<-tab-> jack,
|<-tab-><-tab-> a dull boy);
