network: ipv4acd: first probe address and then assign it
Previously, if IPv4 ACD is enabled on an address, then we first
assign the address, and start sd-ipv4acd daemon for the address.
This is not only RFC incompliant, but also the address is always
dropped, as the daemon always considers the address is conflicted.
This commit makes networkd first starts sd-ipv4acd daemon to probe
the address, and then the address is configured if no conflict is
detected.

network: address: do not send tentative flag
Currently, networkd does not set tentative flag on create, and kernel

behaviour. This is just a preparation for later commits.

This introduces a callback which intend to a library user, e.g.

This graphic chip doesn't have a DRM driver and fallback to vesa-framebuffer

Without this patch, users of such chip suddenly see their GUI broken without
any indication or reason of what happened (no error message). Hence this
regression is near to impossible to troubleshoot for end users.

sd-netlink: do not trigger assertion by calling socket_broadcast_group_unref() with an arbitrary group number
socket_broadcast_group_unref() is only called in netlink_slot_disconnect(),
so the assertion should not be triggered as the match slot was
successfully created.
But, we usually design `_ref/unref()` functions as they can be called
for any inputs. So, let's also follow the design rule here.
We checked the wrong field, which was always NULL here, so we would always
reject the assignment. We would also print the wrong string in the error

core: do not set nosuid mount option when SELinux is enabled
The mount option has special meaning when SELinux is enabled. To make
NoNewPrivileges=yes not break SELinux enabled systems, let's not set the
mount flag on such systems.
Let's re-enable that feature now. As reported when the original commit
was merged, this causes some trouble on SELinux enabled systems. So,
in the subsequent commit, the feature will be disabled when SELinux is enabled.
But, anyway, this commit just re-enable that feature unconditionally.
This fixes repart's, systemctl's, sysusers' and tmpfiles' specifier
expansion to honour the root dir specified with --root=. This is
relevant for specifiers such as %m, %o, … which are directly sourced
from files on disk.
This doesn't try to be overly smart: specifiers referring to runtime
concepts (i.e. boot ID, architecture, hostname) rather than files on the
medium are left as is. There's certainly a point to be made that they
should fail in case --root= is specified, but I am not entirely convinced
about that, and it's certainly something we can look into later if
there's reason to.
I wondered for a while how to hook this up best, but given that quite a
large number of specifiers resolve to data from files on disks, and most
of our tools needs this, I ultimately decided to make the root dir a
first class parameter to specifier_printf().
