deda1a0791 systemd: Add RemoveOnStop=yes to all sockets
Currently we only set this for the main sockets, which means
that

  $ systemctl stop virtqemud.socket

will make the socket disappear from the filesystem while

  $ systemctl stop virtqemud-ro.socket

won't. Get rid of this inconsistency.

826931e95a systemd: Add Also between sockets
This results in all sockets for a service being enabled when a
single one of them is.

The -tcp and -tls sockets are intentionally excluded, because
enabling them should require explicit action on the
administrator's part; moreover, disabling them should not result
in the local sockets being disabled too.

b5cdfb2e43 systemd: Drop parametrization from libvirtd sockets
Up until now the files have been used as template for most
services, but now that those have been converted to common
templates we can drop parametrization and make it clear that
these files are for libvirtd only.

b56a833243 util: drop support for obsolete systemd in RHEL-7
The systemd version in RHEL-7 lacked support for the LISTEN_FDNAMES env
variable with socket activation. Since we stopped targetting RHEL-7 we
can drop some considerable amount of compatibility code.

cc5311e730 systemd: honour $runstatedir in socket unit files
If a systemd socket uses /var/run in its path, systemd prints a warning
at runtime

[   15.139976] systemd[1]: /usr/lib/systemd/system/virtlockd.socket:5:
  ListenStream= references a path below legacy directory /var/run/,
  updating /var/run/libvirt/virtlockd-sock → /run/libvirt/virtlockd-sock;
  please update the unit file accordingly.

This minimal change updates the socket unit files to honour the
$runstatedir path.

There's no functional change by default yet since both expressions
expand to the same value.

b2390c3c25 remote: conditionalize systemd socket unit files
Prepare for reusing libvirtd socket unit files with other daemons by
making various parts of their config conditionally defined by the make
rules.

ee04bfaf9d remote: update config files to note usage wrt systemd socket activation
Certain libvirtd.conf settings are not honoured when using systemd
socket activation.

Certain systemd unit file settings must match those defined in
libvirtd.conf for systemd socket activation to work with systemd
version < 227, otherwise libvirtd cannot determine which inherited
FD to use for which service.

2c3e08b0e3 remote: add systemd socket units for UNIX/TCP sockets
We don't do socket activation of libvirtd, since we need to
unconditionally start libvirtd in order to perform autostart. This
doesn't mean we can't have systemd socket units. Some use cases will
not need libvirt's autostart & are thus free to use activation.
