resolved: rework NSEC covering tests

This makes two changes: first of all we will now explicitly check
whether a domain to test against an NSEC record is actually below the
signer's name. This is relevant for NSEC records that chain up the end
and the beginning of a zone: we shouldn't alow that NSEC record to match
against domains outside of the zone.

This also fixes how we handle NSEC checks for domains that are prefixes
of the NSEC RR domain itself, fixing #8164 which triggers this specific
case. The non-wildcard NSEC check is simplified for that, we can
directly make our between check, there's no need to find the "Next
Closer" first, as the between check should not be affected by additional
prefixes. For the wild card NSEC check we'll prepend the asterisk in
this case to the NSEC RR itself to make a correct check.

core: enumerate perpetual units in a separate per-unit-type method

Previously the enumerate() callback defined for each unit type would do
two things:

1. It would create perpetual units (i.e. -.slice, system.slice, -.mount and
   init.scope)

2. It would enumerate units from /proc/self/mountinfo, /proc/swaps and
   the udev database

With this change these two parts are split into two seperate methods:
enumerate() now only does #2, while enumerate_perpetual() is responsible
for #1. Why make this change? Well, perpetual units should have a
slightly different effect that those found through enumeration: as
perpetual units should be up unconditionally, perpetually and thus never
change state, they should also not pull in deps by their state changing,
not even when the state is first set to active. Thus, their state is
generally initialized through the per-device coldplug() method in
similar  fashion to the deserialized state from a previous run would be
put into place. OTOH units found through regular enumeration should
result in state changes (and thus pull in deps due to state changes),
hence their state should be put in effect in the catchup() method
instead. Hence, given this difference, let's also separate the
functions, so that the rule is:

1. What is created in enumerate_perpetual() should be started in
   coldplug()

2. What is created in enumerate() should be started in catchup().

This makes sure that any device changes that might have happened while
we were restarting/reloading will be noticed properly. For that we'll
now properly serialize/deserialize both the device unit state and the
device "found" flags, and restore these initially in the "coldplug"
phase of the manager deserialization. While enumerating the udev devices
during startup we'll put together a new "found" flags mask, which we'll
the switch to in the "catchup" phase of the manager deserialization,
which follows the "coldplug" phase.

Note that during the "coldplug" phase no unit state change events are
generated, which is different for the "catchall" phase which will do
that. Thus we correctly make sure that the deserialized state won't pull

hwdb: add accel mount settings for Cube i7 Stylus I8L Model (#9207)

There are different Cube i7 Stylus generations.

Those are identified with the printed serial code sticker on motherboard (Printed serial code on casing is not always true)

Order of Model (Old - New):

    W
    WA
    WWA
    WN(I8WN)
    I8L(With W on casing)

I own a I8L generation so the hw identification for my model does not work.
