Many sandboxing options add implicit DeviceAllow rules, which might be confusing
for users running systemd-analyze security and not expecting it.
Print the list.

1449b0f8a9 fixed seccomp arch check for the offline case,
but broke it for the normal case, as when coming from D-Bus the
list of seccomp architectures is already converted to string.

We reject too-short packets in client_receive_message_raw(), so
the packets that dhcp_packet_verify_headers() gets are of sufficient size.
But let's add an assert to clarify this for the reader.
Closes#23223.
This adds support for searching for credentials more comprehensively.
Specifically, unless an absolute source path is specified we'll now
search for the credentials in the system credentials first, and then in
/etc/credstore/, /run/credstore/, and /usr/lib/credstore, making these
dirs hence the recommended place for credentials to leave in the system.
For LoadCredentialEncrypted= we'll also look into
/etc/credstore.encrypted/, /run/credstore.encrypted/, …. These dirs are
hence suitable for credentials whose provenience isn't trusted (e.g.
UEFI creds from systemd-stub), and thus require to be authenticated
before use.
Let's beef up our system credential game a bit, and explicitly import
creds from sd-stub, from qemu fw_cfg and the kernel cmdline and expose
them in the same way as those passed in from nspawn.
Specifically, this will imprt such credentials to
/run/credentials/@system (if the source can be trusted, as in the
qemu/kernel cmdline case) and /run/credentials/@encrypted (otherwise,
such as sd-stub provided ones).
Once imported we'll set the $CREDENTIALS_PATH env var for PID 1, like it
would be done by a container manager for the payload. (Conversely, we'll
also creat a symlink from /run/credentials/@system to whatever is set in
$CREDENTIALS_PATH in case we are invoked by a container manager, thus
providing a fixed path where system credentials are found).
In one of the next commits we want to add support for importing system
credentials from qemu_fw_cfg, very early during boot. (So that we can
use the credentials therein for generators and even earlier). But that
means udev won#t load these modules for us, we have to load them
manually first.
Allows to quickly build systemd-boot by itself without having to
reference the full path of the build target:
$ ninja -C foo systemd-stub
ninja: Entering directory `foo'
[21/21] Generating src/boot/efi/linuxx64.efi.stub with a custom command
$ ninja -C foo systemd-boot
ninja: Entering directory `foo'
[10/10] Generating src/boot/efi/systemd-bootx64.efi with a custom command
Allows to 'meson install --tags systemd-boot --no-rebuild' to install only the EFI
binaries, skipping the rest, for a very quick build:
$ ninja src/boot/efi/linuxx64.efi.stub
[21/21] Generating src/boot/efi/linuxx64.efi.stub with a custom command
$ ninja src/boot/efi/systemd-bootx64.efi
[10/10] Generating src/boot/efi/systemd-bootx64.efi with a custom command
$ DESTDIR=/tmp/foo meson install --tags systemd-boot --no-rebuild
Installing src/boot/efi/systemd-bootx64.efi to /tmp/foo/usr/lib/systemd/boot/efi
Requires Meson 0.60 to be used, prints a warning for unknown keyword
in earlier versions, but there's no failure

On several CI environments, it seems that some loop block devices and
corresponding bdi devices are sometimes removed during the test is
running. Let's exclude them.
Fixes#22970.
Given we have two different types for the journal object flags and the
Compression enum, let's make the latter a regular non-sparse enum, and
thus remove some surprises. We have to convert anyway between the two,
and already do via COMPRESSION_FROM_OBJECT().
The compression helpers are used both in journal code and in coredump
code, and there's a good chance we'll use them later for other stuff.
Let's hence move them into src/basic/, to make them a proper internal
API we can use from everywhere where that's desirable. (pstore might be
a candidate, for example)
No real code changes, just some moving around, build system
rearrangements, and stripping of journal-def.h inclusion.
