network: change UseGateway= default to UseRoutes= setting
...
Anyone previously using the UseRoutes=false parameter expected their
dhcp4-provided gateway route to be ignored, as well. However, with
the introduction of the UseGateway= parameter, this is no longer true.
In order to keep backwards compatibility, this sets the UseGateway=
default value to whatever UseRoutes= has been set to.

network: Fix split in `SendOption=` on client and server
...
When specifying `DHCPv4.SendOption=`, it is used by systemd-networkd to
set the value of that option within the DHCP request that is sent out.
This differs to setting `DHCPServer.SendOption=`, which will place all
the options together as suboptions into the vendor-specific information
(code 43) option.
This commit adds two new config options, `DHCPv4.SendVendorOption=` and
`DHCPServer.SendVendorOption=`. These both have the behaviour of the old
`DHCPServer.SendOption=` flag, and set the value of the suboption in the
vendor-specific information option.
The behaviour of `DHCPServer.SendOption=` is then changed to reflect
that of `DHCPv4.SendOption=`. It will set the value of the corresponding
option in the DHCP request.

network,udev: refuse .link and .network settings with no matches
...
Two releases ago we started warning about this, and I think it is now to turn
this into a hard error. People get bitten by this every once in a while, and
there doesn't see to be any legitimate use case where the same .link or
.network files should be applied to _all_ interfaces, since in particular that
configuration would apply both to lo and any other interfaces. And if for
whatever reason that is actually desired, OriginalName=* or Name=* can be
easily added to silence the warning and achieve the effect.
(The case described in #12098 is particularly nasty: 'echo -n >foo.network'
creates a mask file, 'echo >foo.network' creates a "match all" file.)
Fixes #717 , #12098 for realz now.

Media Access Control Security (MACsec) is an 802.1AE IEEE
industry-standard security technology that provides secure
communication for all traffic on Ethernet links.
MACsec provides point-to-point security on Ethernet links between
directly connected nodes and is capable of identifying and preventing
most security threats, including denial of service, intrusion,
man-in-the-middle, masquerading, passive wiretapping, and playback attacks.

network: drop sections contain invalid settings in network_verify()
...
If e.g., an [Address] section has an invalid setting, then
previously assigned settings in the section is freed, and
only later settings are stored. That may cause partially broken
section stored in Network object.
This makes if an invalid setting is found, then set 'invalid' flag
instead of freeing it. And invalid sections are dropped later by
network_verify().

This test case is a bit silly, but it shows that our code is unprepared to

configured, so let's just emit a warning and cut the list short.

networkd: use OrderedSets instead of strvs to store lists of domains
...
We were already using OrderedSets in the manager object, but strvs in the
configuration parsing code. Using sets gives us better scaling when many
domains are used.
In oss-fuzz #13059 the attached reproducer takes approximately 30.5 s to be
parsed. Converting to sets makes this go down to 10s. This is not _vastly_
faster, but using sets seems like a nicer approach anyway. In particular, we
avoid the quadratic de-unification operation after each addition.
