core: introduce a new job mode JOB_RESTART_DEPENDENCIES
This new job mode will enqueue a start job for a unit, and all units
depending on the unit will get a restart job enqueued. This is then used
for automatic sevice restarts: the unit itself is only started, the
depending units restarted. This way the unit will not go down
unnecessarily, triggering OnSuccess= needlessly.
This also introduces a new state SERVICE_AUTO_RESTART_QUEUED that is
entered once the restart jobs are enqueued. Previously we'd stay in
SERVICE_AUTO_RESTART, but that's problematic, since we'd lose
information whether we still need to enqueue the restart job during a
serialization/deserialization cycle or not. By having an explicit state
for this we know exactly whether we still need to enqueue the job or
not. It's also good since when we are in SERVICE_AUTO_RESTART_QUEUED we
want to act on unit_start(), but on SERVICE_AUTO_RESTART we want to wait
for the holdoff time to pass before we act on unit_start().
network: delay to configure address until it is removed on reconfigure
When we request an address that already exists and is under removing,
we need to wait for the address being removed. Otherwise, configuration
of a route whose preferred source is the address will fail.

dbus-cgroup: Make sure we overwrite cpuset properties in drop-in
The DBUS property setter overwrites the value of the property but
writes a drop-in that extends the value. Let's make sure the drop-in
overwrites the property value as well by assigning the empty string
first.
Let's rename the unit to systemd-battery-check.service. We usually want
to name our own unit files like our tools they wrap, in particular if
they are entirely defined by us (i.e. not just wrappers of foreign
concepts)
While we are at it, also hook this in from initrd.target, and order it
against initrd-root-device.target so that it runs before the root device
is possibly written to (i.e. mounted or fsck'ed).
This is heavily inspired by @aafeijoo-suse's PR #28208, but quite
different ;-)
static versions of libsystems.so are not really supportable, and
encourages mix&match which we cannot really support. Make the wording
about this stronger in the README, since people apparently don'd read to
the last paragraph.

udev-builtin-net_id: align VF representor names with VF names
Certain cards support to set their eswitch to switchdev mode. In this
mode for each created VF there is also created so called VF representor.
This representor is helper network interface used for configuration of
mentioned eswitch and belongs to an appropriate PF.
VF representors are identified by the specific value of phys_port_name
attribute and the value has format "pfMvfN" where M is PF function
number and N is VF number inside this PF.
As the VF representor interfaces belong to PF PCI device the naming
scheme used for them is the same like for other PCI devices. In this
case name of PF interface is used and phys_port_name suffix is appended.
E.g.
PF=enp65s0f0np0 # phys_port_name for PF interface is 'p0'
VF=enp65s0f0np0v0 # v0 is appended for VF0 in case of NAMING_SR_IOV_V
REP=enp65s0f0np0pf0vf0 # phys_port_name for VF0 representor is 'pf0vf0'
First as the phys_port_name for representors is long (6+ chars) then the
generated name does not fit into IFNAMSIZ so this name is used only as
alternate interface name and for the primary one is used generic one
like eth<N>. Second 'f0' and 'pf0' in REP name is redundant.
This patch fixes this issue by introducing another naming scheme for VF
representors and appending 'rN' suffix to PF interface name for them.
N is VF number so the name used for representor interface is similar to
VF interface and differs only by the suffix.
For the example above we get:
PF=enp65s0f0np0
VF=enp65s0f0np0v0
REP=enp65s0f0np0r0
This eases for userspace to determine which representor interface
represents particular VF.
mount-util: tweak flags decoding in mount_verbose_full()
Fine-tune the decoding of mount options in mount_verbose_full() to
provide more helpful log output:
1. decode changing of propagation changes
2. discern changing of superblock flags/mount option string from mount
flags
3. don't check secondary fields when deciding which mount op is
executed, only the flags decide that.

sd-dhcp6-lease: ignore invalid byte(s) at the end of the packet
Oracle Cloud sends malformed DHCPv6 replies that have an invalid
byte at the end, which cannot be parsed as an option code.
networkd currently can cope with the invalid option (it is ignored),
but the whole packet is ignored altogether because of the additional
null at the end.
It's better to be liberal in what we accept and actually assign an
address, given that the reply contains a valid IA_NA.

network: Add `IgnoreDdontFragment=` option for Fragmentation control (#28131)
From `ip-link(8)`:
> [no]ignore-df - enables/disables IPv4 DF
suppression on this tunnel. Normally datagrams
that exceed the MTU will be fragmented; the
presence of the DF flag inhibits this, resulting
instead in an ICMP Unreachable (Fragmentation
Required) message. Enabling this attribute causes
the DF flag to be ignored.
If this option is enabled for a GRE/GRETAP tunnel, the `DF` flag in the outer IP header
will not inherit the inner IP header's `DF` flag.
This is useful to transfer packets that exceed the MTU of the underlay
network.

execute: add support for XDG_STATE_HOME for placing service state data in --user mode
This adds support for the new XDG_STATE_HOME env var that was added to
the xdg basedir spec. Previously, because the basedir spec didn't know
the concept we'd alias the backing dir for StateDirectory= to the one
for ConfigurationDirectory= when runnin in --user mode. With this change
we'll make separate. This brings us various benefits, such as proper
"systemctl clean" support, where we can clear service state separately
from service configuration, now in user mode too.
This does not come without complications: retaining compatibility with
older setups is difficult, because we cannot possibly identitfy which
files in existing populated config dirs are actually "state" and which
one are true" configuration.
Hence let's deal with this pragmatically: if we detect that a service
that has both dirs configured only has the configuration dir existing,
then symlink the state dir to the configuration dir to retain
compatibility.
This is not great, but it's the only somewhat reasonable way out I can
see.
execude: include RuntimeScope field in ExecParameters
