It is a bit odd to do this, because usually libnm-glib-aux is not
about network related stuff. But that is not true entirely, because
it also contains NMIPAddr and other related helper funcitons.
NMLinkType is only a plain enum, there is no logic beyond it.
As such, I think it's acceptable to move it here.
There reason to do this, is that I want to move NMUtilsIPv6IfaceId and
nm_utils_get_ipv6_interface_identifier() out of src/core/, and since
that API is also trival helpers without complex state, it fits to
libnm-glib-aux. As such, we will need also NMLinkType there.
With systemd-resolved, NetworkManager considers `/etc/resolv.conf`
unmanaged. This breaks hostname lookups in a subtle way: when a new
connection comes online, NM will initiate the hostname lookup *before*
propagating DNS updates to systemd-resolved, which of course will cause
the request to fail. And because NM doesn't update `/etc/resolv.conf`,
it doesn't emit a `CONFIG_CHANGED` signal which would've restarted the
lookup.
Fix this by emitting a signal also when using a caching DNS plugin.

Avoid dependencies but explicitly link the static library where it is
used.
This also fixes that we linked libnm-log-core into
libnm-settings-plugin-ifcfg-rh.so, which duplicated the symbols
while it should used them from NetworkManager.
We have a number of static helper libraries. When a user is using such a
library, they need to set the include search paths (-I) and link with
the static library at the right place.
The first part, the include search path, is now trivial. We no longer
add the individual search paths but everybody uses "-I. -Isrc/".
The second part means that when we build a shared library or an
executable that uses symbols from the static library, we need to link
it. But only then, and not earlier so that not multiple intermediate
build products (static libraries too) contain the same code. Note that
for libnm-device-plugin-*.so and other core plugins it's even that
those shared modules should not themselves link with the static
helpers. Instead, the need to use the symbols from NetworkManager.
Easy enough. Previously, we would sometimes define dependencies in
meson. But as it's really simple, I think that those dependencies
obfuscate more than help. Instead drop them, and only explicitly link
where we need it. The exception is libNetworkManagerTest_dep, which
is still a dependency. Maybe that dependency is fine, as it is much
later in the process. Or maybe that will also be replaced in the future.
This file was intended to be used by VPN plugins (by copying it).
However, it was also used internally.
Split the file, and move the internally used part to libnm-glib-aux.
The part that is only there for out of tree users, moves to
"nm-compat.h".
"nm-test-utils.h" is a header-only, helper library for our unit tests.
It was somewhat unmotivated in "shared/nm-utils", because all tests use
it, but it was not part of a "module".
Move it to "src/libnm-glib-aux/". It fits there very well. They both
have (only) a dependency on glib.
The bond option ad_actor_system only matters (and is available) with
mode=802.3ad.
When you create a new bond, the sysctl value will be set to "00:00:00:00:00:00".
So this seems to be a valid value, and in fact the default value for
this option. However, kernel will fail with EINVAL to set the sysctl to
"00:00:00:00:00:00". Kernel fails both if the value is already
"00:00:00:00:00:00" (i.e. setting the same value results in an error) and
it also fails otherwise (i.e. we cannot ever reset the value to
"00:00:00:00:00:00", at least not via sysfs).
Avoid the warning in the common case, where the value is already as
expected.
Otherwise, we still get the warning and won't be able to set the right
value. But this is really a limitation of the kernel API where we cannot
do anything about it (in NetworkManager).

A connection with key-mgmt=wpa-psk should be able to connect to WPA,
WPA2 and WPA3 APs, choosing the best candidate automatically.
Also pass SAE (WPA3) key-mgmt to wpa_supplicant when it is supported.
For example, I now get this when connecting to a WPA2 network:
<info> [1613749711.2915] Config: added 'key_mgmt' value 'WPA-PSK WPA-PSK-SHA256 FT-PSK SAE FT-SAE'
fixes segfault with iwd backend after upgrade to NetworkManager 1.30.0

Before this commit, in AP mode, WPS is started by default and there is no
possibility to disable it. The methods provided as WPS sources seem to
differ from device to device. With some Wifi USB sticks running in AP mode,
the WPS config methods contain "Keypad". Then, I get a pin entry dialog on
Windows machines, even if no pin is configured.
This merge request wires the existing 802-11-wireless-security.wps-method
with wpa_supplicant's configuration to allow disabling WPS.
glib requires G_LOG_DOMAIN defined so that log messages are labeled
to belong to NetworkManager or libnm.
However, we don't actually want to use glib logging. Our library libnm
MUST not log anything, because it spams the user's stdout/stderr.
Instead, a library must report notable events via its API. Note that
there is also LIBNM_CLIENT_DEBUG to explicitly enable debug logging,
but that doesn't use glib logging either.
Also, the daemon does not use glib logging instead it logs to syslog.
When run with `--debug`.
Hence, it's not useful for us to define different G_LOG_DOMAIN per
library/application, because none of our libraries/applications should
use glib logging.
It also gets slightly confusing, because we have the static library like
`src/libnm-core-impl`, which is both linked into `libnm` (the library)
and `NetworkManager` (the daemon). Which logging domain should they use?
Set the G_LOG_DOMAIN to "nm" everywhere. But no longer do it via `-D`
arguments to the compiler.

"libnm-core/" is rather complicated. It provides a static library that
is linked into libnm.so and NetworkManager. It also contains public
headers (like "nm-setting.h") which are part of public libnm API.
Then we have helper libraries ("libnm-core/nm-libnm-core-*/") which
only rely on public API of libnm-core, but are themself static
libraries that can be used by anybody who uses libnm-core. And
"libnm-core/nm-libnm-core-intern" is used by libnm-core itself.
Move "libnm-core/" to "src/". But also split it in different
directories so that they have a clearer purpose.
The goal is to have a flat directory hierarchy. The "src/libnm-core*/"
directories correspond to the different modules (static libraries and set
of headers that we have). We have different kinds of such modules because
of how we combine various code together. The directory layout now reflects
this.
/route/ip6: NMPlatformSignalAssert: ../src/core/platform/tests/test-route.c:449, test_ip6_route(): failure to accept signal one time: 'ip6-route-changed-added' ifindex 0 (2 times received)
By default a connection is retried 4 times before it is blocked from
autoconnecting. This means that if a user specifies an explicit DHCP
timeout in the initrd command line, NM will wait up to 4 times more.
Instead, set the "connection.autoconnect-retries" property of
connections always to 1, so that NM only waits for the time
specified.
Before this commit a default DHCP connection would take at most (45 x
4) seconds. Since the multiplier is now only 1, also increase the DHCP
timeout to have a total time of (90 x 1) seconds, which is the half
than before.
