589397a277 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.

38b38500c6 tree-wide: use "hostname" spelling everywhere 
It's not that I think that "hostname" is vastly superior to "host name". Quite
the opposite — the difference is small, and in some context the two-word version
does fit better. But in the tree, there are ~200 occurrences of the first, and
>1600 of the other, and consistent spelling is more important than any particular
spelling choice.

74a2726869 network: can: introduce a config parser function for bitrates 
For now, this function is nearly equivalent to the si_uint64 parser, except for
an additional range check as Linux only takes 32-bit values as bitrates. In
future, this may also be used to introduce fancier bitrate config formats.

7354900ddd 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.

864edb39cf network: rename SendOptions= to SendOption= 
The name with plural made more sense where multiple options could be specified
in one line. After changes in the pull request, this option only accepts one
value, so from users' POV it should be singular.

(The field in the data structure remains plural, because it actually stores
multiple values.)

800603524a networkd: drop DHCPv4 config on stop, keep on restart, by default 
This partially reverts 95355a281c.

It seems that other parts of link_stop_clients() should be skipped
when restarting, but I don't know enough about those other clients to have
an opinion if it is better to stop&start them on restart or not.
Anyway, that can be done in later patches now that the support for restarts
is there.

Fixes #13625.

afe42aef39 dhcp4: make IPServiceType configurable 
IPServiceType set to CS6 (network control) causes problems on some old
network setups that continue to interpret the field as IP TOS.

Make DHCP work on such networks by allowing this field to be set to
CS4 (Realtime) instead, as this maps to IPTOS_LOWDELAY.

81962db798 network: Introduce MACsec 
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.

Closes #5754

93b4dab57e networkd: Allow to retain configs even if carrier is lost 
When there is bad link in the network the carrier goes up/down.
This makes networkd stops all the clients and drop config.
But if the remote router/dhcpserver running a prevention
of DHCP Starvation attack or DHCP Flood attack it does not allow
networkd to take a DHCP lease resulting failure in configuration.
This patch allows to keep the client running and keep the conf
also for this scenario.

125f20b4de networkd-network: Introduce DHCPv6 PD knob for RFC 7084 WPD-4 
RFC 7084, WPD-4, requires Customer Edge end routers to behave
according to the following:

"WPD-4:  By default, the IPv6 CE router MUST initiate DHCPv6 prefix
           delegation when either the M or O flags are set to 1 in a
           received Router Advertisement (RA) message.  Behavior of the
           CE router to use DHCPv6 prefix delegation when the CE router
           has not received any RA or received an RA with the M and the
           O bits set to zero is out of scope for this document."

Since it cannot be automatically detected whether DHCPv6 is to be
operated as an CE end router or whether to initiate an Informational
exchange to obtain other useful network information via DHCPv6 when the
Router Advertisement 'O' bit is set, a 'ForceDHCPv6PDOtherInformation'
boolean network configuration option in the '[DHCP]' section of a is
introduced. Setting this option causes DHCPv6 to be started in stateful
mode, although only the 'O' bit is seen in the Router Advertisement.

When 'ForceDHCPv6PDOtherInformation' is set and the Router Advertisement
has only the Other information 'O' bit set, disable requests for IA_NA
addresses.

Fixes #9745.
