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.

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.
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.
This reverts commit b1543c4c93.
We check b->address anyway, no need to check the return value,
especially given that the other #ifdef branch don't get the same
treatment.
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.

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.
We should use the data if we can (if stdin/stdout is an AF_UNIX socket),
but still work if we can't (if stdin/stdout are pipes, like in the SSH
case).

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.

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.
