The scope name, even according to our docs is
"machine-$DRIVER\x2d$VMNAME.scope" virSystemdMakeScopeName would use the
resource partition name instead of "machine-" if it was specified thus
creating invalid scope paths.
This makes libvirt drop cgroups for a VM that uses custom resource
partition upon reconnecting since the detected scope name would not
match the expected name generated by virSystemdMakeScopeName.
The error is exposed by the following log entry:
debug : virCgroupValidateMachineGroup:302 : Name 'machine-qemu\x2dtestvm.scope' for controller 'cpu' does not match 'testvm', 'testvm.libvirt-qemu' or 'machine-test-qemu\x2dtestvm.scope'
for a "/machine/test" resource and "testvm" vm.
Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1238570
systemd-machined introduced a new method CreateMachineWithNetwork
that obsoletes CreateMachine. It expects to be given a list of
VETH/TAP device indexes for the host side device(s) associated
with a container/machine.
This falls back to the old CreateMachine method when the new
one is not supported.
Rename the VIR_MOCK_IMPL* macros to VIR_MOCK_WRAP*
and add new VIR_MOCK_IMPL macros which let you directly
implement overrides in the preloaded source.

I got a build failure when cross-compiling to mingw with the
mingw64-dbus package installed:
CC virmockdbus_la-virmockdbus.lo
../../tests/virmockdbus.c:29:6: error: 'dbus_connection_set_change_sigpipe' redeclared without dllimport attribute: previous dllimport ignored [-Werror=attributes]

Well duh - mingw lacks dlopen and friends, even if it can support
dbus. A similar failure occured in virsystemdtest.c; but in that
file, we know that systemd is a Linux-only concept.

Any source file which calls the logging APIs now needs
to have a VIR_LOG_INIT("source.name") declaration at
the start of the file. This provides a static variable
of the virLogSource type.

Commit a1cbe4b5 added a check for spaces around assignments and this
patch extends it to checks for spaces around '=='. One exception is
virAssertCmpInt where comma after '==' is acceptable (since it is a
macro and '==' is its argument).

If systemd is installed, but is not the init system,
systemd-machined fails with an unhelpful error message:
Launch helper exited with unknown return code 1
Currently we only check if the "machine1" service is
available (in ListActivatableNames).
Also check if "systemd1" service is registered with DBus
(ListNames).
This fixes https://bugs.gentoo.org/show_bug.cgi?id=493246#c22
The test case average timing code has not been used by any test
case ever. Delete it to remove complexity.

The problem is described by [0] but its effect on libvirt is that
starting a container with a full distro running systemd after having
stopped it simply fails.
The container cleanup now calls the machined Terminate function to make
sure that everything is in order for the next run.

A cross build to mingw fails with:
CC virsystemdtest-virsystemdtest.o
../../tests/virsystemdtest.c: In function 'testCreateNoSystemd':
../../tests/virsystemdtest.c:97:9: error: implicit declaration of function 'unsetenv' [-Werror=implicit-function-declaration]
unsetenv("FAIL_NO_SERVICE");
^
../../tests/virsystemdtest.c:97:9: error: nested extern declaration of 'unsetenv' [-Werror=nested-externs]
We could cop out and pull in the gnulib unsetenv module. But when
you stop and think about it, this test requires LD_PRELOAD to work,
and systemd is a Linux-only concept anyways, both of which mean
the test could never work on mingw in the first place. Simpler is
to just fix the test to behave like our other LD_PRELOAD tests.

The change to query org.freedesktop.DBus.ListActivatableNames
to detect systemd broke the test suite, since we did not have
stubs to respond to this dbus call.

There are some interesting escaping rules to consider when dealing
with systemd slice/scope names. Thus it is helpful to have APIs
for formatting names

If systemd machine does not exist, return -2 instead of -1,

To register virtual machines and containers with systemd-machined,
and thus have cgroups auto-created, we need to talk over DBus.
This is somewhat tedious code, so introduce a dedicated function
to isolate the DBus call in one place.
