Let's mention the new way to install the latest changes without
rebuilding the image. Let's also remove the duplicate info about
distribution packages that is already mentioned in its own section.
mkosi: Copy packages to the build directory as well
With the latest mkosi, mkosi -t none can be used to rerun the build
script without messing with a previously built image. This allows
one to run "mkosi -t disk -f qemu" in one terminal to build and boot
an image in qemu and then run "mkosi -t none" in another terminal to
rebuild the packages. If one then has "RuntimeBuildSources=yes" set
in their mkosi configuration, the build directory is mounted into the
virtual machine, which means that one can then run "dnf upgrade
/work/build/*.rpm" from within the VM to install the new packages.
This allows for quickly iterating on changes without having to rebuild
the image all the time.
We'll probably want to document this at some point, but let's start
with making it possible by copying the built packages to the build directory.
mkosi: Make sure we don't hide errors from git merge-base
Currently if git merge-base fails we'll hide the error and exit with
exit status 0. Let's make we only exit early if git merge-base exits
with 1 which indicates the current commit is not on the target branch.
Any other error is considered fatal.

hwdb: Add some HP IR cameras
Two very similar devices, with two functions - a regular camera and IR.
The peculiarity of their infrared camera is that it uses a color image
format (YUYV), although it is essentially black and white.
The IR camera interface differs from the regular camera interface by name:
"HP Wide Vision FHD Camera: HP W" for the regular camera and
"HP Wide Vision FHD Camera: HP I" for an infrared camera
Therefore, glob *I is used to separate the IR camera

meson: Define __TARGET_ARCH macros required by bpf
These are required by the bpf_tracing.h header in libbpf, see
https://github.com/libbpf/libbpf/blob/master/src/bpf_tracing.h.
bpf_tracing.h does have a few fallbacks in case __TARGET_ARCH_XXX
is not defined but recommends using the __TARGET_ARCH macros instead
so let's do that.
coredump: correctly take tmpfs size into account for compression
We calculate the amount of uncompressed data we can write by taking the limits
into account and halving it to ensure there's room for switching to compression
on the fly when storing cores on a tmpfs (eg: due read-only rootfs).
But the logic is flawed, as taking into account the size of the tmpfs storage
was applied after the halving, so in practice when an uncompressed core file
was larger than the tmpfs, we fill it and then fail.
Rearrange the logic so that the halving is done after taking into account
the tmpfs size.
These functions after all write EFI UTF-16 strings, i.e. are relatively
high-level, hence give them a specific name indicating the type, to
match our other helpers that have similar type suffixes.

test: split the resolved test suite into separate test cases
Although being far from ideal and the first two test cases have to be run
before the setup phase otherwise they will fail, it still makes the test
suite look much better and easier to read
This addresses an issued introduced by 278e815bfa3e4c2e3914e00121c37fc844cb2025, which dropped the a dependency
from user@.service systemd-user-sessions.service without replacement.
While dropping that dependency does make sense, it should have been
replaced with the weaker dependency on systemd-logind.service, hence fix
that now.
user@.service is after all a logind concept, hence logind really should
be around for its lifetime.
systemd-user-sessions.service is a later milestone that only really
should apply to regular users (not root), hence it's too strong a
requirement.

Use read_full_file_full() in read_smbios11_field()
read_virtual_file() will only read up to page size bytes of data
from /sys/firmware/dmi/entries/.../raw so let's use read_full_file_full()
instead to make sure we read all data.
This should be safe since smbios11 data can be considered immutable
during the lifetime of the system.
Various of our tools operate on block devices, and it's not always
obvious to know which block devices are actually appropriate for use.
Hence, let's add a helper that allows to list block devices, and
supports some limited filtering.
mountpoint-util: use the FID stuff for detecting the root of mounts
In the unlikely event that sandboxes block statx() but let
name_to_handle_at() through it's a good way to determine the root inode
of the namespace, since its parent inode will have the same FID and
mnt_id.
mountpoint-util: add new helper name_to_handle_at_try_fid()
Newer kernels support a new flag for name_to_handle_at(): AT_HANDLE_FID.
This flag is supposed to return an identifier for an inode that we can
use for checking inode identity. It's supposed to be a replacement for
checking .st_ino which doesn't work anymore today because inode numbers
are no longer unique on file systems (not on overlayfs, and not on btrfs
for example). Hence, be a good citizen and add infrastructure to support
AT_HANDLE_FID. Unfortunately that doesn't work for old kernels, hence
add a fallback logic: if we can use the flag, use it. If we cannot use
name_to_handle_at() without it, which might give us a good ID too. But
of course tha tcan fail as well, which callers have to check.

mkfs-util: Set sector size for btrfs as well
btrfs used to default the sector size to the page size and didn't

core/unit: follow merged units before updating SourcePath= timestamp too
Currently, we only follow merged units for unit_load_dropin() call.
