cgroup: add support for memory.swap.current
In systemctl-show we only show current swap if ever swapped or non-zero. This
reduces the noise on swapless systems, that would otherwise always show a swap
value that never has the chance to become non-zero. It further reduces the
noise for services that never swapped.

core: fix array size in unit_log_resources()

test: use Type=notify together with `busctl monitor`
Let's use the newly gained feature of `busctl` and start is as a
Type=notify unit, which should make sure the unit is started only after
`busctl` is on the bus listening for messages.
This should help with a race spotted in CIs, where we continued too
early after starting `busctl monitor` and miss the emitted signals:
This is pretty much the same stuff as `resolvectl monitor` does, and
allows us to run `busctl monitor` in a Type=notify unit which ensures
that `busctl` is really listening for messages once the unit is marked
as started.
Currently test_setpriority_closest assumes that setting RLIMIT_NICE to 30 will
fail if the process is unprivileged. If it succeeds, it assumes that the
process is privileged and setresuid and setresgid will succeed.
However, if RLIMIT_NICE is already >= 30, then setrlimit will succeed even if
the process is unprivileged. Guard against that by checking for permission
errors in setresuid and setresgid and skipping the full test if so.

journalctl: verify sealed log epochs are continuous
Currently empty epochs are not sealed. This allows an attacker to truncate
a sealed log and continue it without any problems showing when verifying the
log.
This partially addresses CVE-2023-31438. One way to extend this change to
address CVE-2023-31438 completely, would be to verify that there is exactly
one seal per epoch (and not sealing when the epoch has not ended yet).
the change also adds a journal-file flag: HEADER_COMPATIBLE_SEALED_CONTINUOUS
this flag indicates that a journal file is sealed continuously and decides whether
any missing crypto epochs should trigger a warning or an error.

Then, this fixes the following issues:
- if dns_packet_append_zone() for other transaction is failed with
EMSGSIZE, the previously added key was not removed,
- if dns_transaction_prepare() for other transaction returns 0, then
we restated the loop without dropping previously appended keys, which
might not be necessary any more.

COREDUMP_CGROUP= - doc where wrong, actually covered COREDUMP_PROC_CGROUP=

If the kernel image is not specified let's imply using

drop the kernel into, which we generally recommend people to use.
If the kernel is not found there, don't try to automatically pick the
kernel path, and fail, as before.
tree-wide: take in all *our* JSON structures also decimal strings
Let's be friendly in what we accept: whenever we define a JSON
structure, let's also allow decimal strings where we want an integer.
This patch purely replaces JSON_VARIANT_UNSIGNED by
_JSON_VARIANT_TYPE_INVALID in the various JsonDispatch[] tables, so that
we'll happily accept any type in json_dispatch(), so that
json_dispatch_uint64() and related tools can do their thing.
This does not switch over OCI (as a JSON structure not defined by us).
json: teach dispatch logic to also take numbers formatted as strings
JSON famously is problematic with integers beyond 53 bits, because
JavaScript stores everything in double precision floating points.
Various implementations in other languages can deal with signed 64 bit
integers, and a few can deal with unsigned 64bit too (like ours).
Typically program that need more then 53 bit of accuracy encode integers
as decimal strings, to make sure that even if consumers can't really
process larger values they at least won't corrupt the data while passing
it along. This is also recommended by JSON-I (RFC 7493)
To maximize compatibility with other implementations let's add 1st class
parsing support for such objects in the json_dispatch() API.
This makes json_dispatch_uint64() and related calls parse such
integers-formatted-as-decimal-strings as uint64_t. This logic will only
be enabled if the "type" field of JsonDispatch is left unspecified (i.e.
set to negative/_JSON_VARIANT_TYPE_INVALID) though, hence alone does not
change anything in effect.
This purely is about consuming such values, whether we should genreate
them also is a discussion for a separate PR.
