Moving all of the gnu-efi detection into src/boot/efi/meson.build makes
more sense than having it partially split.
And thanks to subdir_done() we can simplify the code a lot.
Fixes: #21258
Defines a "UNIT_DEPENDENCY_SLICE_PROPERTY" UnitDependencyMask type that
is used when adding slices to the dependencies hashmap. This type is
used to remove slice dependencies when they get overridden by new ones.
Fixes#20182
Our goal here (as in the previous commits) is to ensure that a settings
file loaded in --settings=override mode is truly a NOP. Previously this
was not the case as we'd drop CAP_NET_ADMIN from the caps if the
settings file didn't enable networking.
With this change we'll drop it only if explicitly turned off in the
settings file, and otherwise let the built-in defaults and cmdline
params reign supreme as documented.

Let's only pick this up from the settings if actually set.
As in the previous commit this makes sure that an empty settings file in
--settings=override mode is really a NOP.
Let's turn these three fields into tristates, so that we can distinguish
whether they are not configured at all from explicitly turned off.
Let#s then use this to ensure that we only copy the settings fields into
our execution environment if they are actually configured.
We already do this for some of the boolean settings, this adds it for
the missing ones.
The goal here is to ensure that an empty settings file used in
--settings=override mode (i.e. the default mode used in the
systemd-nspawn@.service unit) is truly a NOP.
The new helper returns whether the settings file had *any* networking
setting configured at all. We already have a similar helper
settings_private_network() which returns a similar result. The
difference is that the new helper will return true when the private
network was explicitly turned off, while the old one will only return
true if configured and enabled.
We'll reuse the helper a 2nd time later on, but even without it it makes
things a bit more readable.
To properly detect how much space we have to distribute we need to take
into account that both the partition offset and the partition size
aren't aligned.
If we operate on a disk that has a pre-existing unaligned partition
(i.e. one that doesn't start on multiple of 4K, or doesn't have a size
of multiple 4K), then the amount of space after it to distribute among
partitions isn't a multiple of 4K either. So far we might end up
passing the remaining fraction to any partition that wanted it, which
was usually the first one after it that is newly defined. This then
confused the later placement algorithm, since it assumed all partitions
we newly allocate were properly aligned but by being extended by the
fractional space they wouldn't be anymore.
Let's hence fix that by ensuring we never pass space to later partitions
so that things wouldn't be aligned anymore.
Anything that is left-over then at the very end (i.e. typically exactly
the remaining fraction) is added as padding to the existing, unaligned
partition, so that it can't confuse anyone.

This fixes a bad memory access when we destroy an inotify source handler
from the handler itself, and thus destroy the associated inotify_data
structures.
