homework: add new helper call that can shift home dir UID/GID ranges
This new helper is not used yet, but it's useful for apply UID/GID
shifts so that the underlying home dir can use an arbitrary UID (for
example "nobody") and we'll still make it appear as owned by the target
UID.
This operates roughly like this:
1. The relevant underlying UID is mapped to the target UID
2. Everything in the homed UID range except for the target UID is left
unmapped (and thus will appear as "nobody")
3. Everything in the 16bit UID range outside of the homed UID
range/target UID/nobody user is mapped to itself
4. Everything else is left unmapped (in particular everything outside of
the 16 bit range).
Why do it like this?
The 2nd rule done to ensure that any files from homed's managed UID
range that do not match the user's own UID will be shown as "unmapped"
basically. Of course, IRL this should never happen, except if people
managed to manipulate the underlying fs directly.
The 3rd rule is to allow that if devs untar an OS image it more or
less just works as before: 16bit UIDs outside of the homed range will
be mapped onto themselves: you can untar things and tar it back up and
things will just work.

homework: rework directory backend to set up mounts in /run/systemd/user-home-mount before moving them to /home
This does what we already do for the LUKS backend: instead of mounting
the source directory directly to the final home dir, we instead bind
mount it to /run/systemd/user-home-mount (where /run/ is unshared and
specific to our own mount namespace), then adjust its mount flags and
then bind mount it in a single atomic operation into the final
destination, fully set up.
This doesn't improve much on its own, but it makes things a tiny bit
more correct: this way MS_NODEV/MS_NOEXEC/MS_NOSUID will already be
applied when the bind mount appears in the host mount namespace, instead
of being adjusted after the fact.
Doing things this way also makes things work more like the LUKS backend,
reducing surprises. Most importantly it's preparation for doing
uidmapping for directory homes, added in a later commit.

- /sys/class/dmi/id/sys_vendor
- /sys/class/dmi/id/board_vendor
- /sys/class/dmi/id/bios_vendor
With Oracle's physical servers, both `/sys/class/dmi/id/sys_vendor` and
`/sys/class/dmi/id/board_vendor` contain `Oracle Corporation`, so those
servers are detected as `oracle` (VirtualBox).
VirtualBox has the following values in the latest versions:
- /sys/class/dmi/id/product_name: `VirtualBox`
- /sys/class/dmi/id/sys_vendor: `innotek GmbH`
- /sys/class/dmi/id/board_vendor: `Oracle Corporation`
- /sys/class/dmi/id/bios_vendor: `innotek GmbH`

older versions of VirtualBox, while changing the second checked value
from `Oracle Corporation` to `VirtualBox` will reliably detect later and future

json: do something remotely reasonable when we see NaN/infinity
JSON doesn't have NaN/infinity/-infinity concepts in the spec.
Implementations vary what they do with it. JSON5 + Python simply
generate special words "NAN" and "Inifinity" from it. Others generate
"null" for it.
At this point we never actually want to output this, so let's be
conservative and generate RFC compliant JSON, i.e. convert to null.
One day should JSON5 actually become a thing we can revisit this, but in
that case we should implement things via a flag, and only optinally
process nan/infinity/-infinity.
This patch is extremely simple: whenever accepting a
nan/infinity/-infinity from outside it converts it to NULL. I.e. we
convert on input, not output.

mount-util: move opening of /proc/self/mountinfo into bind_remount_one_with_mountinfo()
Let's move things around a bit, and open /proc/self/mountinfo if needed
inside of bind_remount_one_with_mountinfo(). That way bind_remount_one()
can become a superthin inline wrapper around
bind_remount_one_with_mountinfo(). Main benefit is that we don't even
have to open /p/s/mi in case mount_setattr() actually worked for us.

mount-util: use modern mount_setattr() syscall for bind_remount_one_with_mountinfo()
New kernels have a nice syscall for changing bind mount flags. Let's use
it. This makes the complex libmount based iteration logic unnecessary.

efivars: skip writing if variable is already in wanted state
In order to minimize EFI variable NVRAM wear, do not rewrite variables
if they are already in the wanted state (i.e. same data and attributes).
This allows e.g. performing repeat calls of "bootctl install" (which
always rewrites the EFI boot entry) without consuming EFI NVRAM write
cycles.

homed: don't drop caches on activation
We should drop caches if we are configured to do so in all cases where
we are done with home dir operations: except if that operation is
activation, because in that case we are not destroying anything, but
leaving it on.
Hence, turn off the flag that reminds us that we should drop caches
before exiting, once activation completed fully,

nspawn: bump RLIMIT_NOFILE for nspawn payload similar to how host PID 1 does it for its payload
We try to pass containers roughly the same rlimits as the host gets from
the kernel. However, this means we'd set the RLIMIT_NOFILE to 4K. Which
is quite limiting though, and is something we actually departed from in
PID1: since
52d620757817bc0fa7de3ddbe43024544ced7ea0 we raise the limit
substantially for all userspace.
Given that nspawn is quite often invoked without proper PID1, let's raise the
limits for container payloads the same way as we do from the real PID1
to its service payloads.

process-util: move sync() out of freeze()
We are using this for creating userns namespaces, and we really
shouldn't try to sync there. Moreover the use of free() in shutdown code
doesn't need it anyway, since it just sync()ed right before anyway. Only
the third user of freeze() we have actually needs the syc(), hence do it
there and nowhere else.
