nspawn: move payload to sub-cgroup first, then sync cgroup trees
if we sync the legacy and unified trees before moving to the right
subcgroup then ultimately the cgroup paths in the hierarchies will be
out-of-sync... Hence, let's move the payload first, and sync then.

udev-rules: make tape-changers also apprear in /dev/tape/by-path/
It is important to be able to access tape changer ("Medium Changers") by
persistant name.
While tape devices can be accessed via /dev/tape/by-id/ and
/dev/tape/by-path/, tape-changers could only be accessed by
/dev/tape/by-id/.
However, in some cases, especially when accessing Amazon Webservice
Storage Gateway VTLs (or accessing iSCSI VTLs in general?) this does not
work, as all tape devices and the tape changer have the same ENV{ID_SERIAL}.
The results is, that only the last device is available in
/dev/tape/by-id/, as the former devices have been overwritten.
As this behavior is hard to change without breaking consistentcy,
this additional device in /dev/tape/by-path/ can be used to access the medium changes.
The tape devices can also be accessed by this path.
The content of the directory will now look like:
# SCSI tape device, rewind (unchanged)
/dev/tape/by-path/$env{ID_PATH} -> ../../st*
# SCSI tape device, no-rewind (unchanged)
/dev/tape/by-path/$env{ID_PATH}-nst -> ../../nst*
# SCSI tape changer device (newly added)
/dev/tape/by-path/$env{ID_PATH}-changer -> ../../sg*
Tape devices and tape changer have different ID_PATHs.
SCSI tape changer get the suffix "-changer"
to make them better distinguishable from tape devices.

test: store coredumps in journal
To make debugging much easier, especially for crashes in tests under
QEMU, let's store the entire coredump bundle in the systemd journal,
which is usually kept around by various CIs. Right now, we usually end
up with a journal, but without the coredump itself, which is pretty
useless.

If the QEMU_SMP value has not been explicitly set, try to determine it

This change should significantly help when running integration tests

swap: finish the secondary swap units' jobs if deactivation of the primary swap unit fails
Currently, if deactivation of the primary swap unit fails:

Job for dev-mapper-fedora\x2dswap.swap failed.
See "systemctl status "dev-mapper-fedora\\x2dswap.swap"" and "journalctl -xe" for details.
then there are still the running stop jobs for all the secondary swap units
that follow the primary one:
# systemctl list-jobs
JOB UNIT TYPE STATE

3230 dev-disk-by\x2did-dm\x2dname\x2dfedora\x2dswap.swap stop running
3234 dev-fedora-swap.swap stop running
5 jobs listed.
This remains endlessly because their JobTimeoutUSec is infinity:
# LANG=C systemctl show -p JobTimeoutUSec dev-fedora-swap.swap
JobTimeoutUSec=infinity
If this issue happens during system shutdown, the system shutdown appears to
get hang and the system will be forcibly shutdown or rebooted 30 minutes later
by the following configuration:
# grep -E "^JobTimeout" /usr/lib/systemd/system/reboot.target
JobTimeoutSec=30min
JobTimeoutAction=reboot-force
The scenario in the real world seems that there is some service unit with
KillMode=none, processes whose memory is being swapped out are not killed
during stop operation in the service unit and then swapoff command fails.
On the other hand, it works well in successful case of swapoff command because
the secondary jobs monitor /proc/swaps file and can detect deletion of the
corresponding swap file.
This commit fixes the issue by finishing the secondary swap units' jobs if
deactivation of the primary swap unit fails.

pid1: make sure to restore correct default values for some rlimits
Commit
fb39af4ce42d7ef9af63009f271f404038703704 forgot to restore the default
rlimit values (RLIMIT_NOFILE and RLIMIT_MEMLOCK) while PID1 is reloading.
This patch extracts the code in charge of initializing the default values for
those rlimits in order to create dedicated functions, which take care of their
initialization.
These functions are then called in parse_configuration() so we make sure that
the default values for these rlimits get restored every time PID1 is reloading
its configuration.

sysctl: let's by default increase the numeric PID range from 2^16 to 2^22
This should PID collisions a tiny bit less likely, and thus improve
security and robustness.
2^22 isn't particularly a lot either, but it's the current kernel
limitation.
Bumping this limit was suggested by Linus himself:
https://lwn.net/ml/linux-kernel/CAHk-=wiZ40LVjnXSi9iHLE_-ZBsWFGCgdmNiYZUXn1-V5YBg2g@mail.gmail.com/
Let's experiment with this in systemd upstream first. Downstreams and
users can after all still comment this easily.
Besides compat concern the most often heard issue with such high PIDs is
usability, since they are potentially hard to type. I am not entirely sure though
whether
4194304 (as largest new PID) is that much worse to type or to
copy than 65563.
This should also simplify management of per system tasks limits as by
this move the sysctl /proc/sys/kernel/threads-max becomes the primary
knob to control how many processes to have in parallel.

bus-message: introduce two kinds of references to bus messages
Before this commit bus messages had a single reference count: when it
reached zero the message would be freed. This simple approach meant a
cyclic dependency was typically seen: a message that was enqueued in a
bus connection object would reference the bus connection object but also
itself be referenced by the bus connection object. So far out strategy
to avoid cases like this was: make sure to process the bus connection
regularly so that messages don#t stay queued, and at exit flush/close
the connection so that the message queued would be emptied, and thus the
cyclic dependencies resolved. Im many cases this isn't done properly
however.
With this change, let's address the issue more systematically: let's
break the reference cycle. Specifically, there are now two types of
references to a bus message:
1. A regular one, which keeps both the message and the bus object it is
associated with pinned.
2. A "queue" reference, which is weaker: it pins the message, but not
the bus object it is associated with.
The idea is then that regular user handling uses regular references, but
when a message is enqueued on its connection, then this takes a "queue"
reference instead. This then means that a queued message doesn't imply
the connection itself remains pinned, only regular references to the
connection or a message associated with it do. Thus, if we end up in the
situation where a user allocates a bus and a message and enqueues the
latter in the former and drops all refs to both, then this will detect
this case and free both.
Note that this scheme isn't perfect, it only covers references between
messages and the busses they are associated with. If OTOH a bus message
is enqueued on a different bus than it is associated with cyclic deps
cannot be recognized with this simple algorithm, and thus if you enqueue
a message associated with a bus A on a bus B, and another message
associated with bus B on a bus A, a cyclic ref will be in effect and not
be discovered. However, given that this is an exotic case (though one
that happens, consider systemd-bus-stdio-bridge), it should be OK not to
cover with this, and people have to explicit flush all queues on exit in
that case.
Note that this commit only establishes the separate reference counters
per message. A follow-up commit will start making use of this from the
bus connection object.

be specified using related option, NUMAMask. Default mask can be
overwritten on per-service level.

shared/cpu-set-util: only force range printing one time
The idea is to have at least one range to make the new format clearly
distinguishable from the old. But it is enough to just do it once.
In particular, in case the affinity would be specified like 0, 2, 4, 6…,
this gives much shorter output.

pid1: when reloading configuration, forget old settings
If we had a configuration setting from a configuration file, and it was
removed, we'd still remember the old value, because there's was no mechanism to
"reset" everything, just to assign new values.
Note that the effect of this is limited. For settings that have an "ongoing" effect,
like systemd.confirm_spawn, the new value is simply used. But some settings can only
be set at start.
In particular, CPUAffinity= will be updated if set to a new value, but if
CPUAffinity= is fully removed, it will not be reset, simply because we don't
know what to reset it to. We might have inherited a setting, or we might have
set it ourselves. In principle we could remember the "original" value that was
set when we were executed, but propagate this over reloads and reexecs, but
that would be a lot of work for little gain. So this corner case of removal of
CPUAffinity= is not handled fully, and a reboot is needed to execute the
change. As a work-around, a full mask of CPUAffinity=0-8191 can be specified.

pid1: don't reset setting from /proc/cmdline upon restart
We have settings which may be set on the kernel command line, and also
in /proc/cmdline (for pid1). The settings in /proc/cmdline have higher priority
of course. When a reload was done, we'd reload just the configuration file,
losing the overrides.
So read /proc/cmdline again during reload.
Also, when initially reading the configuration file when program starts,
don't treat any errors as fatal. The configuration done in there doesn't
seem important enough to refuse boot.

pid1: parse CPUAffinity= in incremental fashion
This makes the handling of this option match what we do in unit files. I think
consistency is important here. (As it happens, it is the only option in
system.conf that is "non-atomic", i.e. where there's a list of things which can
be split over multiple assignments. All other options are single-valued, so
there's no issue of how to handle multiple assignments.)

Rework cpu affinity parsing
The CPU_SET_S api is pretty bad. In particular, it has a parameter for the size
of the array, but operations which take two (CPU_EQUAL_S) or even three arrays
(CPU_{AND,OR,XOR}_S) still take just one size. This means that all arrays must
be of the same size, or buffer overruns will occur. This is exactly what our
code would do, if it received an array of unexpected size over the network.
("Unexpected" here means anything different from what cpu_set_malloc() detects
as the "right" size.)
Let's rework this, and store the size in bytes of the allocated storage area.
The code will now parse any number up to 8191, independently of what the current
kernel supports. This matches the kernel maximum setting for any architecture,
to make things more portable.
Fixes #12605.
