swap: replace Discard= setting by a more generic Options= setting
For now, it's systemd itself that parses the options string, but as soon
as util-linux' swapon can take the option string directly with -o we
should pass it on unmodified.

udev hwdb: Support shipping pre-compiled database in system images
In some cases it is preferable to ship system images with a pre-generated
binary hwdb database, to avoid having to build it at runtime, avoid shipping
the source hwdb files, or avoid storing large binary files in /etc.
So if hwdb.bin does not exist in /etc/udev/, fall back to looking for it in
UDEVLIBEXECDIR. This keeps the possibility to add files to /etc/udev/hwdb.d/
and re-generating the database which trumps the one in /usr/lib.
Add a new --usr flag to "udevadm hwdb --update" which puts the database
into UDEVLIBEXECDIR.
Adjust systemd-udev-hwdb-update.service to not generate the file in /etc if we
already have it in /usr.
While GNOME/KDE are generally capitalized, systemd tools generally are
not, hence let's not start doing so in the XDG_CURRENT_SESSION
environment variable.
selinux: make sure we do not try to print missing fields
UID or GID of 0 is valid, so we cannot use that to distinguish whether
calls to sd_bus_creds_get_* succeeded, and the return value from the
function is the only way to know about missing fields. Print "n/a" if
the fields are missing.
units: define appropriate job timeout actions when boot or shutdown timeouts are hit
Using the new JobTimeoutAction= setting make sure we power off the
machine after basic.target is queued for longer than 15min but not
executed. Similar, if poweroff.target is queued for longer than 30min
but does not complete, forcibly turn off the system. Similar, if
reboot.target is queued for longer than 30min but does not complete,
forcibly reboot the system.
The system start timeout as previously implemented would get confused by
long-running services that are included in the initial system startup
transaction for example by being cron-job-like long-running services
triggered immediately at boot. Such long-running jobs would be subject
to the default 15min timeout, esily triggering it.
Hence, remove this again. In a subsequent commit, introduce per-target
job timeouts instead, that allow us to control these timeouts more
finegrained.

shared: in-addr-utils - add default_subnet_mask and default_prefixlen methods
These use the (deprecated) IPv4 address classes to deduce the corresponding subnet masks. This is useful when addresses
without subnet masks and prefix lengths are given.
Make use of these new functions from sd-dhcp-lease.

shutdown: do final unmounting only if not running inside the container
If we run in the container then we run in a mount namespace. If namespace dies
then kernel should do unmounting for us, hence we skip unmounting in containers.
Also, it may be the case that we no longer have capability to do umount,
because we are running in the unprivileged container.

util: introduce sethostname_idempotent
Function queries system hostname and applies changes only when necessary. Also,
migrate all client of sethostname to sethostname_idempotent while at it.
Commit 74055aa762 'journalctl: add new --flush command and make use of
it in systemd-journal-flush.service' broke flushing because journald
checks for the /run/systemd/journal/flushed file before opening the
permanent journal. When the creation of this file was postponed,
flushing stoppage ensued.
sd-bus: if we don't manage to properly allocate the error message for an sd_bus_error, just go on
sd_bus_error_setfv() must initialize the sd_bus_error value to some
sensible value and then return a good errno code matching that. If it
cannot work at all it should set the error statically to the OOM error.
But if it can work half-way (i.e. initialize the name, but not the
message) it should do so and still return the correct errno number for
it.
calendar: make freeing a calendar spec object deal fine with NULL
In order to make object destruction easier (in particular in combination
with _cleanup_) we usually make destructors deal with NULL objects as
NOPs. Change the calendar spec destructor to follow the same scheme.
Using "their" as pronoun in these places is confusing since it is more
associated with plural rather than singular, and the sentence already
contains a plural. The word "her/his" apparently offends some people,
hence let's avoid the problem altogether and just name the noun again.
Fix a bug in systemd-cryptsetup-generator which caused the drop-in

name different than the unit name.

shutdown: pass own argv to /run/initramfs/shutdown
Since commit b1e90ec515408aec2702522f6f68c4920b56375b systemd passes
its log settings to systemd-shutdown via command line parameters.
However, systemd-shutdown doesn't pass these parameters to
/run/initramfs/shutdown, causing it to fall back to the default log
settings.
This fixes the following bugs about the shutdown not being quiet
despite "quiet" being in the kernel parameters:
