measure: Take SizeOfImage into account as well for .linux section
Same change as https://github.com/systemd/systemd/pull/34583 but for
systemd-measure. Otherwise we end up with PCR policy digest mismatches
as systemd-stub will measure the full virtual size of the kernel image
after it has been loaded while systemd-measure will disregard the extra
size introduced by SizeOfImage.
While ideally the stub would only measure the data that's actually on
disk and not the uninitialized data introduced by VirtualSize > SizeOfRawData,
we want newer systemd-measure to work with older stubs so we have to fix
systemd-measure and can't fix this in the stub.

GREEDY_REALLOC_APPEND: Make more type safe
Previously, GREEDY_REALLOC_APPEND would compile perfectly fine and cause

cgroup: Add ManagedOOMMemoryPressureDurationSec= override setting for units
This will allow units (scopes/slices/services) to override the default
systemd-oomd setting DefaultMemoryPressureDurationSec=.
The semantics of ManagedOOMMemoryPressureDurationSec= are:
- If >= 1 second, overrides DefaultMemoryPressureDurationSec= from oomd.conf
- If is empty, uses DefaultMemoryPressureDurationSec= from oomd.conf
- Ignored if ManagedOOMMemoryPressure= is not "kill"
- Disallowed if < 1 second
Note the corresponding dbus property is DefaultMemoryPressureDurationUSec
which is in microseconds. This is consistent with other time-based
dbus properties.

journalctl: do not directly use optarg, but copy optarg before use
Otherwise, if the process forks child processes, then the arguments
cannot be used from them.
To avoid potential issues like the one fixed by 6d3012bab4ce4c1ed260598d05b4e9f2ea471658.
Nested mounts should be carried over from host to overlayfs to overlayfs
(and back to host if unmerged). Otherwise you run into hard to debug
issues where merging extensions means you can't unmount those nested mounts
anymore as they are hidden by the overlayfs mount.
To fix this, before unmerging any previous extensions, let's move the nested
mounts from the hierarchy to the workspace, then set up the new hierachy, and
finally, just before moving the hierarchy into place, move the nested mounts
back into place.
Because there might be multiple nested mounts that consists of one or more
mounts stacked on top of each other, we make sure to move all stacked mounts
properly to the overlayfs. The kernel doesn't really provide a nice way to do
this, so we create a stack, pop off each mount onto the stack and then pop from
the stack again to the destination to re-establish the stacked mounts in the same
order in the destination.
core: move debug logging from _can_live_mount() functions to caller
Let's debug log the returned dbus error where we want the logging, but
don't log it, where we don't.
This removes the noisy logging from the property handler for the
CanLiveMount property, but keeps it in place for the MountImage() method
call where we want it.

gpt-auto: remove directory check for ESP mount
Ensure that we always attempt to mount the `ESP` partition to `/boot`
when there is no `XBOOTLDR` partition.
Fixes an issue when booting without a `XBOOTLDR` partition and an empty
root partition, since it would mount the `ESP` partition to `/efi/`
unconditionally causing boot entries to not be under `/boot/` as
recommended by the Boot Loader Specification.
This PidRef just track some data, but cannot be used for any active
operation.
Background: for https://github.com/systemd/systemd/pull/34703 it makes
sense to track explicitly if some PidRef is not a local one, so that we
never attempt to for example "kill a remote process" and thus
acccidentally hit the wrong process (i.e. a local one by the same PID).
let's rename the "_ts" flavour of these calls "_full" instead, exposing
the full functionality. And then keep two more minimal versions around:
one "_at" (which has the ts parameter suppressed, but keeps the dir_fd
one). And one without suffix (which supresses both).
Do the same for the label versions of these calls.
