efi: explicitly cast physical address to UINTN when converting to/from pointers
UINTN is the integer type equalling the native ptr size. Let's fix the
casting warnings described in #7788 by casting the the pointers and
values to this type first. That way we cast integers to the right size
first before turning them into pointers, and pointers are first
covnerted to integers of the right size before converting them into
integers.
Not tested, since I lack i386 EFI systems, but I think this is simple
enough to be correct event without testing.

build-sys: Add option to link systemctl statically
Systemctl is special because it is required for many tasks that may need to
be performed when the system is not fully configured and/or partially
broken:
1. Installing/Uninstalling services during OS installs and upgrades
2. Shutting down the system
Therefore reduce the number of dependencies that systemctl pulls in, by
not linking to systemd-shared. This brings a bit of resilience to
systemctl (and its aliases shutdown, reboot, etc), by linking against
less external libraries.
Because this extra resilience comes at a cost of approximately 580 KB
extra space, this is done behind a meson build option.

smack: make mac_smack_fix() deal somewhat sensible with non-absolute paths
This tries to improve the mac_smack_fix() logic a bit, by properly
handling non-absolute paths.
It's still pretty broken though, which is sad for security technology:
non-normalized paths (for example "/usr/../dev/sda") will still not be
treated correctly. I am not sure how to fix that properly though, and I
don't understand SMACK well enough to do so. This fix hence just fixes
to most obvious glaring issue.

sd-bus: make add match method callback slot "floating"
When we allocate an asynchronous match object we will allocate an
asynchronous bus call object to install the match server side.
Previously the call slot would be created as regular slot, i.e.
non-floating which meant installing the match even if it was itself
floating would result in a non-floating slot to be created internally,
which ultimately would mean the sd_bus object would be referenced by it,
and thus never be freed.
Let's fix that by making the match method callback floating in any case
as we have no interest in leaving the bus allocated beyond the match
slot.

sd-bus: add new sd_bus_slot_set_floating() call
This new call allows explicit control of the "floating" state of a bus
slot object. This is useful for creating a bus slot object first,
retaining a reference to it, using it for making changes to the slot
object (for example, set a description) and then handing it over to
sd-bus for lifecycle management.
It's also useful to fix #8551.
