This is similar to OnFailure= but is activated whenever a unit returns
into inactive state successfully.
I was always afraid of adding this, since it effectively allows building
loops and makes our engine Turing complete, but it pretty much already
was it was just hidden.
Given that we have per-unit ratelimits as well as an event loop global

core: add new PropagateStopTo= dependency (and inverse)
This takes inspiration from PropagatesReloadTo=, but propagates
stop jobs instead of restart jobs.
This is defined based on exactly two atoms: UNIT_ATOM_PROPAGATE_STOP +
UNIT_ATOM_RETROACTIVE_STOP_ON_STOP. The former ensures that when the
unit the dependency is originating from is stopped based on user
request, we'll propagate the stop job to the target unit, too. In
addition, when the originating unit suddenly stops from external causes
the stopping is propagated too. Note that this does *not* include the
UNIT_ATOM_CANNOT_BE_ACTIVE_WITHOUT atom (which is used by BoundBy=),
i.e. this dependency is purely about propagating "edges" and not
"levels", i.e. it's about propagating specific events, instead of
continious states.
This is supposed to be useful for dependencies between .mount units and
their backing .device units. So far we either placed a BindsTo= or
Requires= dependency between them. The former gave a very clear binding
of the to units together, however was problematic if users establish
mounnts manually with different block device sources than our
configuration defines, as we there might come to the conclusion that the
backing device was absent and thus we need to umount again what the user
mounted. By combining Requires= with the new StopPropagatedFrom= (i.e.
the inverse PropagateStopTo=) we can get behaviour that matches BindsTo=
in every single atom but one: UNIT_ATOM_CANNOT_BE_ACTIVE_WITHOUT is
absent, and hence the level-triggered logic doesn't apply.

core: add a reverse dep for OnFailure=
Let's add an implicit reverse dep OnFailureOf=. This is exposed via the
bus to make things more debuggable: you can now ask systemd for which
units a specific unit is the failure handler.

that.
Now that deps are a bit cheaper, it should be OK to add deps that only

core: convert Slice= into a proper dependency (and add a back dependency)
The slice a unit is assigned to is currently a UnitRef reference. Let's
turn it into a proper dependency, to simplify and clean up code a bit.
Now that new dep types are cheaper, deps should generally be preferable
over everything else, if the concept applies.
This brings one major benefit: we often have to iterate through all unit
a slice contains. So far we iterated through all Before= dependencies of
the slice unit to achieve that, filtering out unrelated units, and
taking benefit of the fact that slice units are implicitly ordered
Before= the units they contain. By making Slice= a proper dependency,
and having an accompanying SliceOf= dependency type, this is much
simpler and nicer as we can directly enumerate the units a slice
contains.
The forward dependency is actually called InSlice internally, since we
already used the UNIT_SLICE name as UnitType field. However, since we
don't intend to expose the dependency to users as dep anyway (we already
have the regular Slice D-Bus property for this) this shouldn't matter.
The SliceOf= implicit dependency type (the erverse of Slice=/InSlice=)
is exported over the bus, to make things a bit nicer to debug and
discoverable.

easily replace its internal implementation later on.

test-fileio: fix confusing log output
Previously we'd pass all return values of read_virtual_file() to

sometimes return positive one with means "not truncated" but we'd show
as "Permission denied. Let's fix this, and log differently for sucess

sd-device: use strjoina() more again in sd_device_new_from_subsystem_sysname()
This reverts a major part of:
e17c95af8e450caacde692875b30675cea75211f
Using format strings for concatenating strings is pretty unefficient,
and using PATH_MAX buffers unpretty as well. Let's revert to using
strjoina() as before.
However, to fix the fuzz issue at hand, let's explicitly verify the two
input strings ensuring they are valid path names. This includes a length
check (to 2K each), thus making things prettier, faster and using less
memory again.

man: reorder fields in os-release
Let's order the fields from the most general to least: os name, os variant, os
version, machine-parseable version details, metadata, special settings. I added
section headers to roughly group the settings. The division is not strict,
because for example CPE_NAME also includes the version, and PRETTY_NAME may
too, but it still makes it easier to find the right name.
Also split out Examples to separate paragraphs:
almost all descriptions had "Example:" at the end, where multiple
examples were listed. Splitting this out to separate paragraphs
makes the whole thing much easier to read.
Add missing markup and punctuation while at it.
About
- If not set, defaults to <literal>NAME=Linux</literal>.
+ If not set, a default of <literal>NAME=Linux</literal> may be used.
and similar changes: in many circumstances, if this is not set, no value should
be used. The fallback mostly make sense when we need to present something to the
user. So let's reword this to not imply that the default is necessary.
