The main change is that lease address and pd getters changed and the new
functions are now used.
In addition, solved several conflicts due to disabled code and added
adapt header to new files.
GKeyfile changed something about how to handle invalid escape sequences.
As we don't want to test GKeyfile (per-se), just adjust to test to not
hit the problem.

Upstream systemd fixed this compiler warning. What really needs to be
done, is re-importing the upstream code.
In the meantime, suppress the warning that hits on GCC 14.
This is a temporary workaround!

When doing reapply on linux bridge interface, NetworkManager will reset
the VLAN filtering and default PVID which cause PVID been readded to all
bridge ports regardless they are managed by NetworkManager.
This is because Linux kernel will re-add PVID to bridge port upon the
changes of bridge default-pvid value.
To fix the issue, this patch introduce netlink parsing code for
`vlan_filtering` and `default_pvid` of NMPlatformLnkBridge, and use that
to compare desired VLAN filtering settings, skip the reset of VLAN
filter if `default_pvid` and `vlan_filtering` are unchanged.

Older gcc versions don't like this. The _Pragam() itself is to workaround a
-Wnonnull-compare warning with gcc 14.
After all, we use compiler warning extensively. They are our linters and have
necessarily false positives. To make them usable across a wide range of
compilers, is a constant effort.
Here is another one.

Convert these checks to an nm_assert() to suppress the warning.
When we use a "static" array declarator to a function, we understand
and tell the compiler that the argument must not be NULL.
But now gcc-14.0.1-0.2.fc40 starts warning about NULL checks for
such arguments.
static void foo(char args[static 10]) {
nm_assert(args);
sprintf(args, "hi");
}
Granted, the compiler is right, and we know that this condition is not
supposed to be violated. A logical thing would be just to drop the
assertion.
Instead, suppress "-Wnonnull-compare" warnings inside a nm_assert(). An
nm_assert() is more than a run time check, it's an additional
self-documenting code of the invariants.
It's fine to assert for something that is true. Actually, all the
conditions that we assert against, hold. The compiler telling us that
the condition that we assert against is valid, is not useful.
Otherwise, gcc-14.0.1-0.2.fc40 warns:
../src/libnm-core-impl/nm-utils.c: In function _nm_utils_strstrdictkey_create:

Section 4.9 of RFC 4594 specifies that DHCP should use the standard
(CS0 = 0) service class. Section 3.2 says that class CS6 is for
"transmitting packets between network devices (routers) that require
control (routing) information to be exchanged between nodes", listing
"OSPF, BGP, ISIS, RIP" as examples of such traffic. Furthermore, it
says that:
User traffic is not allowed to use this service class. By user
traffic, we mean packet flows that originate from user-controlled
end points that are connected to the network.
Indeed, we got reports of some Cisco switches dropping DHCP packets
because of the CS6 marking.
For these reasons, change the default value to the recommended one,
CS0.
Currently the internal DHCP client sets traffic class "CS6" in the DS
field of the IP header for outgoing packets.
dhclient sets the field according to the definition of TOS (RFC 1349),
which was was deprecated in 1998 by RFC 2474 in favor of DSCP.
Introduce a new property IPvX.dhcp-dscp (currently valid only for
IPv4) to specify a custom DSCP value for DHCP backends that support it
(currently, only the internal one).
Define the default value to CS0, because:
- section 4.9 of RFC 4594 specifies that DHCP should use the standard
(CS0 = 0) service class;
- section 3.2 says that class CS6 is for "transmitting packets
between network devices (routers) that require control (routing)
information to be exchanged between nodes", listing "OSPF, BGP,
ISIS, RIP" as examples of such traffic. Furthermore, it says that:
User traffic is not allowed to use this service class. By user
traffic, we mean packet flows that originate from user-controlled
end points that are connected to the network.
- we got reports of some Cisco switches dropping DHCP packets because
of the CS6 marking.
The client currently always sets the DSCP value in the DS field
(formerly known as "TOS") to CS6. Some network equipment drops packets
with such DSCP value; provide a way to change it.

Previously, input fields for peer attributes such as 'Public Key' were
not pre-populated with the existing settings of the peer. This was due
to the WireGuard peer editor class not setting its peer property during
object construction, as the necessary flag was absent. This commit
addresses and fixes this issue.

In order to make _nm_setting_property_define_direct_enum more flexible,
this patch is introducing property_type argument to it. When set to NULL
it will set property_type to nm_sett_info_propert_type_direct_enum.
Defining the wrong from_dbus/to_dbus functions is something not
probable. The unit test is just getting in the way of those who knows
what they do and force contributors to change the same thing in multiple
places.
It's simply not valid to read the ref-count without an atomic.
The compiler might optimize out the assignment to "r" and read the
_ref_count field multiple times. Thereby, we might at first appear
to be larger than > 1, and later pass 1 to compare-and-exchange.
We need an atomic get here.

an empty strv array should be returned instead of NULL if it hadn't
been created yet.
