3ca1fab70a networkd: merge ll addressing fallback modes into normal "boolean" values 
They are not really boolean, because we have both ipv4 and ipv6, but
for each protocol we have either unset, no, and yes.

From https://github.com/systemd/systemd/issues/13316#issuecomment-582906817:
LinkLocalAddressing must be a boolean option, at least for ipv4:
- LinkLocalAddressing=no => no LL at all.

- LinkLocalAddressing=yes + Static Address => invalid configuration, warn and
  interpret as LinkLocalAddressing=no, no LL at all.

(we check that during parsing and reject)

- LinkLocalAddressing=yes + DHCP => LL process should be subordinated to the
  DHCP one, an LL address must be acquired at start or after a short N
  unsuccessful DHCP attemps, and must not stop DHCP to keeping trying. When a
  DHCP address is acquired, drop the LL address. If the DHCP address is lost,
  re-adquire a new LL address.

(next patch will move in this direction)

- LinkLocalAddressing=fallback has no reason to exist, because LL address must
  always be allocated as a fallback option when using DHCP. Having both DHCP
  and LL address at the same time is an RFC violation, so
  LinkLocalAdressing=yes correctly implemented is already the "fallback"
  behavior. The fallback option must be deprecated and if present in older
  configs must be interpreted as LinkLocalAddressing=yes.

(removed)

- And for IPv6, the LinkLocalAddress option has any sense at all? IPv6-LL
  address aren't required to be always set for every IPv6 enabled interface (in
  this case, coexisting with static or dynamic address if any)? Shouldn't be
  always =yes?

(good question)

This effectively reverts 29e81083bd. There is no
special "fallback" mode now, so the check doesn't make sense anymore.

0e686feaff network: honor M or O flag in RA even if IPv6AcceptRA.DHCPv6Cleint=always 
Follow-up for ac24e418d9.

The original motivation of the commit and RFE #15339 is to start dhcpv6
client in managed mode when neither M nor O flag is set in the RA.
But, previously, if the setting is set to "always", then the DHCPv6
client is always started in managed mode even if O flag is set in the
RA. Such the behavior breaks RFC 7084.

6b000af4f2 tree-wide: avoid some loaded terms 
https://tools.ietf.org/html/draft-knodel-terminology-02
https://lwn.net/Articles/823224/

This gets rid of most but not occasions of these loaded terms:

1. scsi_id and friends are something that is supposed to be removed from
   our tree (see #7594)

2. The test suite defines an API used by the ubuntu CI. We can remove
   this too later, but this needs to be done in sync with the ubuntu CI.

3. In some cases the terms are part of APIs we call or where we expose
   concepts the kernel names the way it names them. (In particular all
   remaining uses of the word "slave" in our codebase are like this,
   it's used by the POSIX PTY layer, by the network subsystem, the mount
   API and the block device subsystem). Getting rid of the term in these
   contexts would mean doing some major fixes of the kernel ABI first.

Regarding the replacements: when whitelist/blacklist is used as noun we
replace with with allow list/deny list, and when used as verb with
allow-list/deny-list.

2a71d57f4e network: clean-up DHCP lease server data configuration 
This is an attempt to clean up the POP3/SMTP/LPR/… DHCP lease server
data logic in networkd. This reduces code duplication and fixes a number
of bugs.

This removes any support for collecting POP3/SMPT/LPR servers acquired
via local DHCP client releases since noone uses that, and given how old
these protocols are I doubt this will change. It keeps support for
configuring them for the dhcp server however.

The differences between the DNS/NTP/SIP/POP3/SMTP/LPR configuration
logics are minimized.

This removes the relevant symbols from sd-network.h (which is an
internal API only at this point after all).

This is unfortunately not well test, given the old code for this had
barely any tests. But the new code should not perform worse at least,
and allow us to release, since it corrects some interfaces visible in
the .network configuration format.

Fixes: #15943

9efa8a3cff network: DHCPv6 Assign delegated prefix to LAN interface 
In DHCPv6-PD environment, where WAN interface requests IPv6 via DHCPv6,
receives the address as well as delegated prefixes, with LAN interfaces
serving those delegated prefixes in their router advertisement messages.
The LAN interfaces on the router themselves do not have
the IPv6 addresses assigned by networkd from the prefix it
serves on that interface. Now this patch enables it.

networkd: Add support for setting a preferred subnet id for IPv6 PD leases 
This allows users to configure a subnet id that should be used instead
of automatically (sequentially) assigned subnets. The previous attempt
had the downside that the subnet id would not be the same between
networkd restarts. In some setups it is desirable to have predictable
subnet ids across restarts of services and systems.

The code for the assignment had to be broken up into two pieces. One of
them is the old (sequential) assignment of prefixes and the other is the
new assignment based on configured subnet ids. The new assignment code
has to be executed first and has to be taken into account when (later
on) allocating the "old" subnets from the same pool.

Instead of having one iteration through the links we are now trying to
allocate a prefix for every link on every delegated prefix, unless they
received an assignment in a previous iteration.

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.

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.
