In one of my recent patches I've introduced new connection
feature VIR_DRV_FEATURE_NETWORK_UPDATE_HAS_CORRECT_ORDER.
However, I forgot to add corresponding case into a switch in
vzConnectSupportsFeature().

The order in which virNetworkUpdate() accepts @section and
@command arguments is not the same as in which it passes them
onto networkUpdate() callback. Until recently, it did not really
matter, because calling the API on client side meant arguments
were encoded in reversed order (compared to the public API), but
then on the server it was fixed again - because the server
decoded RPC (still swapped), called public API (still swapped)
and in turn called the network driver callback (with reversing
the order - so magically fixing the order).
Long story short, if the public API is called even number of
times those swaps cancel each other out. The problem is when the
API is called an odd numbed of times - which happens with split
daemons and the right URI. There's one call in the client (e.g.
virsh net-update), the other in a hypervisor daemon (say
virtqemud) which ends up calling the API in the virnetworkd.
The fix is obvious - fix the order in which arguments are passed
to the callback.
But, to maintain compatibility with older, yet unfixed, daemons
new connection feature is introduced. The feature is detected
just before calling the callback and allows client to pass
arguments in correct order (talking to fixed daemon) or in
reversed order (talking to older daemon).
Unfortunately, older client talking to newer daemon can't be
fixed. Let's hope that it's less frequent scenario.

So far, it was not needed, but shortly a client will want to know
whether virNetworkUpdate() API is fixed or not. See next commits
for more info.
Side note, this driver's implementation is called only when using
sub-driver's connection, i.e. "network:///system". For any other
URI the corresponding hypervisor's driver callback is called.

Just like VFIO devices, vDPA devices may need to have all guest memory
pages locked/pinned in order to operate properly. In the case of VFIO
devices (including mdev and NVME, which also use VFIO) libvirt
automatically increases the locked memory limit when one of those
devices is present. This patch modifies that code to also increase the
limit if there are any vDPA devices present.

This function is a specialized version of
qemuDomainGetMemLockLimitBytes() for PPC64. Simplifying it in the same
manner as the previous patch has the nice side effect of accounting
for the possibility of an mdev device
(I don't know if mdev devices are supported on PPC, but even if not
then a) the additional check for mdev devices gained by using
qemuDomainNeedsVFIO() in place of open coding will be an effective
NOP, and b) if mdev devices are supported on PPC64 in the future, this
function will be prepared for it).

The ESX implementation of virConnectListAllDomains() follows
pretty much implementations in other drivers: it has local array
of virDomainPtr-s which (if requested by caller) is filled by
actual domains or not (if the caller is interested only in the
count of domains).
Anyway, in case of the former, the passed @domains argument is
set to the local array, which is then set to NULL to prevent it
from freeing under cleanup label. Pretty standard pattern.
Except, the local array is set to NULL always. Even if the local
array is not stolen. Fortunately, this doesn't lead to a memory
leak, because if caller is not interested in the array, none is
allocated. But it doesn't set good example and also breaks my
spatch rules.

Some SRIOV PFs don't have a netdev associated with them (the spec
apparently doesn't require it). In most cases when libvirt is dealing
with an SRIOV VF, that VF must have a PF, and the PF *must* have an
associated netdev (the only way to set the MAC address of a VF is by
sending a netlink message to the netdev of that VF's PF). But there
are times when we don't need for the PF to have a netdev; in
particular, when we're just getting the Switchdev Features for a VF,
we don't need the PF netdev - the netdev of the VF (apparently) works
just as well.
Commit 6452e2f5 (libvirt 5.1.0) *kind of* made libvirt work around PFs
with no netdevs in this case - if virNetDevGetPhysicalFunction
returned an error when setting up to retrieve Switchdev feature info,
it would ignore the error, and then check if the PF netdev name was
NULL and, if so it would reset the error object and continue on rather
than returning early with a failure. The problem is that by the time
this special handling occured, the error message about missing netdev
had already been logged, which was harmless to proper operation, but
confused the user.
Fortunately there are only 2 users of virNetDevGetPhysicalFunction, so
it is easy to redefine it's API to state that a missing netdev name is
*not* an error - in that case it will still return success, but the
caller must be prepared for the PF netdev name to be NULL. After
making this change, we can modify the two callers to behave properly
with the new semantics (for one of the callers it *is* still an error,
so the error message is moved there, but for the other it is okay to
continue), and our spurious error messages are a thing of the past.

Commit ac87d3520a consolidated common cgroup code between the QEMU and

virCgroupGetBlkioWeight() went missing.
The result is that 'virsh blkiotune' is setting the blkio.weight for the
guest in the host cgroup, but not on the domain XML, because
virCgroupGetBlkioWeight() is also used to write the blkio.weight value
in the domain object.
Fix it by adding the virCgroupGetBlkioWeight() call in the
virDomainCgroupSetupDomainBlkioParameters() helper.
