kernel-install: silently ignore unexpected arguments for 'remove' command
The shell script version of kernel-install silently ignored unexpected
arguments, but C version refused that. Unfortunately, Fedora's kernel
script specifies kernel file even for 'remove' command. Let's accept
extra arguments and silently ignore them to keep backward compatibility.
This fixes regression introduced in 5a0c810462 with which all requests
for link properties ended up with EINVAL as we kept hitting
the signature_is_single() assert in sd_bus_get_property().
core: copy the host's os-release for /run/host/os-release
Currently for portable services we automatically add a bind mount
os-release -> /run/host/os-release. This becomes problematic for the
soft-reboot case, as it's likely that portable services will be configured
to survive it, and thus would forever keep a reference to the old host's
os-release, which would be a problem because it becomes outdated, and also
it stops the old rootfs from being garbage collected.
Create a copy when the manager starts under /run/systemd/propagate instead,
and bind mount that for all services using RootDirectory=/RootImage=, so
that on soft-reboot the content gets updated (without creating a new file,
so the existing bind mounts will see the new content too).
This expands the /run/host/os-release protocol to more services, but I
think that's a nice thing to have too.
As mentioned in the NEWS entry, it seems to see very little use, but adds
complexity in our code. It was added mainly with the goal of making it easier
for people using grub2 to modify their boot configuration, but grub2 is gaining
support for BLS snippets. On the systemd side, we now have credentials. So
let's deprecate this, and if there's no outcry, remove it in a few releases.

Include in manual what DNSSEC=no means in detail

security-aware recursive name server MUST set DO bit when sending
requests. systemd-resolved does not do that by design. State it more
clearly in manual page. Unlike other implementations it disables not
only validation as it stated, but complete DNSSEC awareness.
analyze: don't warn about version spec compliant versions
This commits adds version_is_valid_versionspec and uses it in
analyze-compare-version.c.
version_is_valid_versionspec differs from version_is_valid in that it acepts
empty strings and since valid characters in a version spec version are all
ASCII letters and digits as well as "-.~^", but ",_+" allowed by
version_is_valid are not.
Also give a more specific warning message on invalid characters.

It's been a while since we introduced Differential ShellCheck and it
proved to be quite useful (and in some ways even better than the shellcheck
run by super-linter). So, to have only one linter scream at us for not
knowing how to write bash properly, let's drop the super-linter's one in
favor of Differential ShellCheck.

Some of the new units using systemd-pcrphase are missing the --graceful
flag which causes them to error if the tpm libraries are not installed.
Add --graceful just like in the other pcrphase units to make systemd-pcrphase
exit gracefully if the tpm libraries are missing.
test-network: correctly support running systemd-udevd from the build dir
We create the udevadm -> systemd-udevd symlink during the install phase,
so it doesn't exist in the just compiled tree. This worked in CI since
the symlink is manually created there post-build.

efi: add helper API for detecting confidential virtualization
This helper is a simplified version of detect_confidential_virtualization()
that merely returns a boolean status flag reflecting whether we are believed
to be running inside a confidential VM.
This flag can be used for turning off features that are inappropriate to
use from a CVM, but must not be used for releasing sensitive data. The
latter must only be done in response to an attestation for the environment.

mkosi now supports CentOS SIGs natively so we drop our own definition
of that and use the mkosi builtin one. We also enable hyperscale for
both CentOS 8 and CentOS 9 for consistency and add epel-next as well
which is a requirement for Hyperscale.
CentOS 8 ships python 3.6 so let's try and stay compatible with that
since the only feature we're using that requires python 3.9 is the
streamlined type annotations which are trivial to convert back to
the older stuff to stay compatible with python 3.6.
kernel-install: Avoid reopening file descriptor via /proc
kernel-install used to work without /proc mounted before the rewrite
in C. Let's restore that property by making sure we don't reopen
file descriptors via /proc. In this case, parse_env_file_fdv() calls
fdopen_independent() to get a FILE * for the given file descriptor
(which itself calls fd_reopen()). Let's avoid the call to
fdopen_independent() by using chase_and_fopenat_unlocked() which
gives us a FILE * immediately without having to reopen any file
descriptors.

proc-cmdline: re-implement proc_cmdline_filter_pid1_args() without using getopt_long()

use getopt_long() in proc_cmdline_filter_pid1_args().
