Also, fix a race condition introduced by d16684fe13:

The script has a shebang and .sh extension, so make it executable

- use `udevadm wait` instead of `udevadm info --wait-initialized`,
- use `timeout` command instead of the fixed time sleep,
- add basic tests for #25106,
- add brief comment about #25115.
This fix unfortunately introduced a much worse regression that
is affecting many users, so let's revert it for now and rework
it in the next release.
This reverts commit 5ded3917a1.
Fixes https://github.com/systemd/systemd/issues/24984
The precise bounds of the scheduling priority depend on the scheduling policy,
so depending on the order in which the two settings are specified the
validation might pass or fail.
When checking the setting only validate the outer range (valid values in general are 0 to 99),
and let the execution fail later if the priority does not match the
specified policy (1 to 99 for RR/FIFO, 0 for the rest).

(s) is just ugly with a vibe of DOS. In most cases just using the normal plural
form is more natural and gramatically correct.
There are some log_debug() statements left, and texts in foreign licenses or
headers. Those are not touched on purpose.
We want to test four things:
- that the transient units are successfully started when drop-ins exist
- that the transient setings override the defaults
- the drop-ins override the transient settings (the same as for a normal unit)
- that things are the same before and after a reload
To make things more fun, we start and stop units in two different ways: via
systemctl and via a direct busctl invocation. This gives us a bit more coverage
of different code paths.
Slices are worth testing too, because they don't need a fragment path so they
behave slightly differently than service units. I'm making this a separate
patch from the actual tests that I wanted to add later because it's complex
enough on its own.
clear_services() is renamed to clear_units() and now takes a full
unit name including the suffix as an argument.
_clear_service() is renamed to clear_unit() and changed likewise.
create_service() didn't have the same underscore prefix, and I don't think
it's useful or needed for a local function, so it is removed.
No functional change.
Allows to skip check that ensures units must not be running.
I have a use case that would use reattach, except the orchestrator
is using a non-standard versioning scheme, so image matching cannot
work. As a workaround, need to be able to detach and then attach
manually, without stopping the units to avoid extended downtimes
and loss of FD store.
Let's remove some sleep loops, and instead:
1. Use Type=notify to wait until "resolvectl monitor" successfully
installed its monitor, so that we know that queries enqueued later
will definitely be seen.
2. Use "grep -m1" to watch "journalctl -f" output to wait precisely for
the RR data we want to see, and immediately exit.
This shortens code quite a bit, and should make it more robust.
