61ff6021d8 vircgroupmock: add support to test cgroup v2
We need to create the cgroup v2 sysfs the same way as we do for
cgroup v1.

This introduces new VIR_CGROUP_MOCK_MODE env variable which will
configure which cgroup mode each test requires.  There are three
different modes:

    - legacy: only cgroup v1 is available and it's the default mode
    - hybrid: both cgroup v1 and cgroup v2 are available and have some
        controllers
    - unified: only cgroup v2 is available

25456e0470 tests: reintroduce tests for libxl's legacy nested setting
The preferred location for setting the nested CPU flag changed in
Xen 4.10 and is advertised via the LIBXL_HAVE_BUILDINFO_NESTED_HVM
define.  Commit 95d19cd0 changed libxl to use the new preferred
location but unconditionally changed the tests, causing 'make check'
failures against Xen < 4.10 that do not contain the new location.

Commit e94415d5 fixed the failures by only running the tests when
LIBXL_HAVE_BUILDINFO_NESTED_HVM is defined. Since libvirt supports
several versions of Xen that use the old nested location, it is
prudent to test the flag is set correctly. This patch reintroduces
the tests for the legacy location of the nested setting.

8b62008d2b vircgrouptest: call virCgroupNewSelf instead virCgroupDetectMounts
This will be required once cgroup v2 is introduced.  The cgroup
detection is not simple and we will have multiple backends so we
should not just jump into the middle of the detection code.

In order to use virCgroupNewSelf we need to create all the remaining
data files:

    - {name}.cgroups represents /proc/cgroups, it is a list of cgroup
      controllers compiled into kernel

    - {name}.self.cgroup represents /proc/self/cgroup, it describes
      cgroups to which the process belongs

For "no-cgroups" we need to modify the expected behavior because
virCgroupNewSelf() will fail if there are no controllers available.

b37b41f868 qemu: Don't duplicate binary name in capabilities
virCapabilitiesAddGuestDomain() takes an optional binary
name: this is intended for cases where a certain domain
type can't use the default one registered for the guest
architecture, but has to use a special binary instead.

The current code, however, will pass 'binary' again when
'kvmbin' is not defined, which is unnecessary as 'binary'
has been registered as default earlier, and will result
in capabilities output such as

  <emulator>/usr/bin/qemu-system-x86_64</emulator>
  <domain type='qemu'/>
  <domain type='kvm'>
    <emulator>/usr/bin/qemu-system-x86_64</emulator>
  </domain>

with the second <emulator> element providing no additional
information.

Change it so that, when 'kvmbin' is not defined, NULL is
passed and so the default emulator will be used instead.

This patch is introducing cache monitor(CMT) to cache and
memory bandwidth monitor(MBM) for monitoring CPU memory
bandwidth.

The host capability of the two monitors is also introduced
in this patch.

For CMT, the host capability is shown like:
  <host>
  ...
    <cache>
      <bank id='0' level='3' type='both' size='15' unit='MiB' cpus='0-5'>

        <feature name='llc_occupancy'/>
      </monitor>
    </cache>
    ...
  </host>

For MBM, the capability is shown like this:
  <host>
    ...
    <memory_bandwidth>
      <node id='1' cpus='6-11'>
        <control granularity='10' min ='10' maxAllocs='4'/>

3e26b476b5 security_manager: Load lock plugin on init
Now that we know what metadata lock manager user wishes to use we
can load it when initializing security driver. This is achieved
by adding new argument to virSecurityManagerNewDriver() and
subsequently to all functions that end up calling it.

The cfg.mk change is needed in order to allow lock_manager.h
inclusion in security driver without 'syntax-check' complaining.
This is safe thing to do as locking APIs will always exist (it's
only backend implementation that changes). However, instead of
allowing the include for all other drivers (like cpu, network,
and so on) allow it only for security driver. This will still
trigger the error if including from other drivers.

7ea7342996 conf: correct false boot order error during domain parse
virDomainDefCollectBootOrder() is called for every item on the list
for each type of device. One of the checks it makes is to gather the
order attributes from the <boot> element of all devices, and assure
that no two devices have been given the same order.

Since (internally to libvirt, *not* in the domain XML) an <interface
type='hostdev'> is on both the list of hostdev devices and the list of
network devices, it will be counted twice, and the code that checks
for multiple devices with the same boot order will give a false
positive.

To remedy this, we make sure to return early for hostdev devices that
have a parent.type != NONE.

This was introduced in commit 5b75a4, which was first in libvirt-4.4.0.
