Drop connections and caches and reload config from files, to allow
for low-interruptions updates, and hook up to the usual SIGHUP and
ExecReload=. Mark servers and services configured directly via D-Bus
so that they can be kept around, and only the configuration file
settings are dropped and reloaded.

This patch fixes an issue where, when not specifiying either at least one
`SocketBindAllow` or `SocketBindDeny` rule, behavior for the bind syscall
filtering would be unexpected.
For example, when trying to bind to a port with only "SocketBindDeny=any"
given, the syscall would succeed:
> systemd-run -t -p "SocketBindDeny=any" nc -l 8080
Expected with this set of rules (also in accordance with the documentation)
would be an Operation not permitted error.
This behavior occurs because a default initialized socket_bind_rule struct
matches what "any" represents. When creating the bpf list all elements get
default initialized, as such represeting "any". Seemingly it is necressarry
to set the size of the map to at least one, as such if no allow rule is
given default initialization and minimal map size cause one any allow rule
to be in the map, causing the behavior observed above.
This patch solves this by introducing a new "match nothing" magic stored in
the rule's address family and setting such a rule as the first one if no
rule is given, making sure that default initialized rule structs are never
used.
Resolves#30556
Rate limiting authentication attempts in the test can cause somewhat
sporadic test failures: adding a test case might suddenly cause future
test cases to fail because of too many authentication attempts too
quickly
We're not trying to test the rate-limiting, we're trying to test the
functionality of homed. So we effectively disable rate-limiting on all
the home areas we create
This makes it possible to update a home record (and blob directory) of a
home area that's either completely absent (i.e. on a USB stick that's
unplugged) or just inaccessible due to lack of authentication
This bypasses authentication (i.e. user_record_authenticate) if the
volume key was loaded from the keyring and no secret section is
provided.
This also changes Update() and Resize() to always try and load the
volume key from the keyring. This makes the secret section optional for
these methods while still letting them function (as long as the home
area is active)
Naming is always a matter of preference, and the old name would certainly work,
but I think the new one has the following advantages:
- A verb is better than a noun.
- The name more similar to "the competition", i.e. 'sudo', 'pkexec', 'runas',
'doas', which generally include an action verb.
- The connection between 'systemd-run' and 'run0' is more obvious.
There has been no release yet with the old name, so we can rename without
caring for backwards compatibility.
dig question with DNSSEC on will now be proxied upstream, i.e. to the
test knot server. This leads to different results, but the result isn't
tha tinteresting since we don't want to test knot, but resolved. Hence
comment this test.
There seems to be something wrong with the test though, as the upstream
server refused recursion, but if so it is not suitable as an upstream
server really, as resolved can only be client to a recursive resolver.
By default socat open a separate r/w channel for each specified address,
and terminates the connection after .5s from receiving EOF on _either_
side. And since one side of that connection is an empty stdin, we reach
that EOF pretty quickly. Let's avoid this by using socat in
"reversed unidirectional" mode, where the first address is used only for
writing, and the second one is used only for reading.

This reverts commit 5e8ff010a1.
This broke all the URLs, we can't have that. (And actually, we probably don't
_want_ to make the change either. It's nicer to have all the pages in one
directory, so one doesn't have to figure out to which collection the page
belongs.)
The follow-up commit will refactor some code in systemd-sysext, so add some
tests to make sure that things didn't break. The tests will be later extended
with cases for new features added.
This is inspired by one of our internal tests that does pretty much the
same thing. However, it is slightly more convoluted than I'd like it to
be, since I really don't want to duplicate the list of our units in
another place, so we need to, somehow, pass the list from the meson file
to the test script. I originally envisioned this to be a part of the
unit test suite, but this doesn't work for unit files with absolute
paths to binaries, as we'd have to install the build first (maybe using
a chroot would work?).
It doesn't check man pages (since they might not be installed on the
test machine) and also skip recursive dependencies (as that would trip
over issues in files that are not under our direct control), but it
should still cover typos and such.
There are currently two units for which the check had to be disabled -
syslog.socket, as the corresponding syslog.service might not be
installed, and rc-local.service as that's a compat API and the necessary
/etc/rc.d/rc.local file may not (and most likely won't be) present.

- Allow to call the method without "name" and "type".
- Allow to specify SD_RESOLVE_NO_TXT and SD_RESOLVE_NO_ADDRESS.
- Allow to provide multiple services, and fix memory leak.
- Rearrange the return value format.
- Encode TXT field with octescape() to make the field matches with the
io.systemd.Resolve.Monitor interface.
Fixes#31371.

After the mentioned commit, when the ExecCommand executable is missing,
and failure will be ignored by manager, we exit with EXIT_SUCCESS at executor
side too. The behavior however contradicts systemd.service(5), which states:
> If the executable path is prefixed with "-", an exit code of the command
> normally considered a failure (i.e. non-zero exit status or abnormal exit
> due to signal is _recorded_, but has no further effect and is considered
> equivalent to success.
and thus makes debugging unexpected failures harder. Therefore, let's still
exit with EXIT_EXEC, but just skip LOG_ERR level log.
