Turns out the libsystemd-daemon library, which we've been
using for the sd_notify() feature, has been deprecated for
a long time and has finally been removed as of systemd 230.
This means 'make rpm' no longer works on Fedora rawhide,
and that other distributions such as Debian sid are silently
disabling the sd_notify() feature.
Switch from libsystemd-daemon to libsystemd.

systemd: Guard the call to sd_notify() properly

New subject: [libvirt] [PATCH 1/3] maint: Use libsystemd instead of libsystemd-daemon
The libsystemd-daemon library had been deprecated upstream
just a few days before we started using it. Talk about bad
timing :)
With systemd 230, now in Debian sid and Fedora rawhide, it
has finally been dropped. We should use libsystemd, its
replacement, instead.

Just unconditionally dropping support for libsystemd-daemon.so
means you require systemd >= 209 for libvirt to build. IMHO
this is too new.
The only thing we use this for is sd_notify() which is a really trivial
method which gets a NUIX socket from NOTIFY_SOCKET env variable, opens
it and just sends across the string. I think we could just implement
this logic trivially ourselvs, and not need to use any library, thus
avoiding the problem with it being moved
Regards,
Daniel

Whether or not we call sd_notify() should depend on the
availability of the function itself, not of the library
that contains it.

ACK series, and I verified things continue to work fine on f24, but rawhide
repos seem to be a bit broken at the moment so I couldn't verify there, but it
looks good to me. Also, when pushing please close this:
