Currently if we detect that a scan finished in
_scan_notify_is_scanning(), we call immediately _scan_kickoff() (which
might start a new scan) and then we check again whether the device can
autoactivate or whether to remove the wifi-scan pending action.
This means that if the scan takes long enough, when
_scan_notify_is_scanning() is called, it is already time to start
another scan and the device activation will be delayed. It will be
delayed until the scan duration becomes shorter than the
exponentially-growing periodic scan interval.
Fix this by delaying the next scan immediately after a scan result.

Our cast macros (like NM_AUTH_SUBJECT()) are plain C pointer casts,
unless when building with more asserts enabled.
Still, they are unnecessary and even their ability to check the type
(with more asserts) is not needed, because we must trust glib's
g_object_new() to return reasonable objects. That is a basic
requirement, that we don't need to assert against.
Also, in the majority of cases we don't do this either.
According to RFC3315 section 15.12, Information-request messages can't
include a IA option (such as IA_NA or IA_PD).
When doing stateless DHCPv6, we start the client in the appropriate
mode to issue an Information-request message: with "-S" for dhclient or
calling sd_dhcp6_client_set_information_request(TRUE) for systemd.
However, if we need a prefix later, the client must be restarted to
ask the prefix. Currently both dhclient and systemd clients are still
configured to send an Information-request with prefixes. Fix that.
The ifindex of a virtual device is set when the kernel link
appears. For OVS interfaces, this happens after NM has added the
record to the ovsdb; since NM needs to know the related port and
bridge when it adds ovs-interface record, and since interfaces are
enslaved when they reach stage3, the ifindex is set during stage3.
This means that the first time
nm_device_activate_schedule_stage3_ip_config_start() is called, the
ifindex is unset. Previously we would just set the firewall state as
initialized and the zone would never be set again. Instead, allow the
zone to be set when re-entering stage3.
nm_device_activate_schedule_stage3_ip_config_start() now always check
for the ifindex. This guarantees that we don't try to change zone for
devices without a kernel link (for example, OVS bridges and ports).
Upon reaching state ip-check, the device now changes the zone also if
an ifindex is present and the zone was not set before. I'm not sure
this can actually happen, because if the device has an ifindex it
should be set during stage3. However I'm leaving this extra check for
completeness.

Failing the system interface device is almost always the right thing
to do when the ovsdb entry is removed.
However, to avoid that a late device-removed signal tears down a
different, newly-activated connection, let's also check that we have a
master. Or in alternative, that the device is assumed/external: in
such case it's always fine to fail the device

If you configure with "--enable-tests=no", then the tests
are not build during `make all`, but only during `make check`.
That is convenient for development, so if you don't work on tests,
they usually don't get build and the (partial) compilation is faster.
However, there is no target to build the tests without running them.
Add `make check-progs` for that.
Currently "src/" mostly contains the source code of the daemon.
I say mostly, because that is not true, there are also the device,
settings, wwan, ppp plugins, the initrd generator, the pppd and dhcp
helper, and probably more.
Also we have source code under libnm-core/, libnm/, clients/, and
shared/ directories. That is all confusing.
We should have one "src" directory, that contains subdirectories. Those
subdirectories should contain individual parts (libraries or
applications), that possibly have dependencies on other subdirectories.
There should be a flat hierarchy of directories under src/, which
contains individual modules.
As the name "src/" is already taken, that prevents any sensible
restructuring of the code.
As a first step, move "src/" to "src/core/". This gives space to
reorganize the code better by moving individual components into "src/".
For inspiration, look at systemd's "src/" directory.

NMUdevClient does not actually implement ref-counting, because it's not
used. Still, the destroy function was named nm_udev_client_unref(),
because theoretically then we could later, as the need arises, make
the type ref-counted. Then unref function already had the right name.
However, NMUdevClient also has a callback function that emits monitor
events. Again for simplicity, this callback function cannot be reset, it
can only be set once (in the constructor) and can also not be unset nor
disabled.
When the user of NMUdevClient is done with the instance and calls
"unref", then it must be sure that the callback is no longer invoked
afterwards. In practice that is already the case, but "unref" makes it
sound as if somebody else could also still hold a reference -- in which
case the user would have to first unset/disable the callback.
Rename the function to "destroy()", so that it's clear that the instance
is gone afterwards and that the callback will not be invoked anymore.
In some cases the enslavement event of a device gets
processed by nm-platform before the master NMDevice is
created, in such cases the enslavement information is simply
lost by NM, to prevent this let NMDevice connect to the
'device-ifindex-changed' signal to be notified of when its master
NMDevice appears so that eventually the NMDevices will be consistent
with the kernel network state.

Bonds need to release all enslaved devices when
the bond mode is to be changed.
Also release slaves when they're external interfaces as
it means the master it's now managed by NetworkManager.

This is the default state for new devices hence they should
return back to this state when unmanaged.

Sometimes the option can't be displayed as is because it contains NULL
or non-ascii characters. Rename the 'hidden' argument of
nm_supplicant_config_add_option_with_type() to 'display_value' so that
callers can pass a preferred string representation of the value.
- the python-black version on Fedora 33 was updated, and this formats
our python code differently. The black version that is used by our
gitlab-ci is the authoritative version that should be used. Update
it by regenerating the containers.
- especially Fedora:rawhide and Debian:sid often introduce changes that
will cause a break of our build. Update the containers to test latest
versions.
Fedora 33's version of python-black is the authoritative version we
use for formatting -- note that formatting may look different depending
on the black version.
Recently, the package was updated to 20.8~b1-1.fc33, which treats
these lines different.
Work around that by adjusting the code so that both older and current
versions of python black behave the same.
