fea0d8c40d qemu: Move <hostdev> SCSI path generation into qemuDomainPrepareHostdev()
When preparing a SCSI <hostdev/> with passthrough of a host SCSI
adapter (i.e. no protocol), a virStorageSource structure is
initialized and stored inside virDomainHostdevDef. But the source
structure is filled in many places, with almost the same code.

Firstly, qemuProcessPrepareHostHostdev() and
qemuConnectDomainXMLToNativePrepareHostHostdev() are the same.

Secondly, qemuDomainPrepareHostdev() allocates the src structure,
only to let qemuProcessPrepareHostHostdev() fill src->path later.

Well, src->path can be filled at the same place where the src
structure is allocated (qemuDomainPrepareHostdev()) which renders
the other two functions needless.

57e4e9791a qemu_hotplug: Drop PCI backend check in qemuDomainAttachHostPCIDevice()
There is no way the qemuDomainAttachHostPCIDevice() function can
be called over a hostdev with PCI backend other than VFIO. And
even if it were, then the check is written so poorly that it lets
some types through (e.g. KVM) only to let
qemuBuildPCIHostdevDevProps() called afterwards fail properly.

Drop this check and rely on qemuDomainPrepareHostdevPCI() (and
worst case scenario even qemuBuildPCIHostdevDevProps()) to report
the proper error.

59962b69b5 qemu: Deny all but VFIO PCI backends in hostdev prepare phase
We used to support KVM and VFIO style of PCI assignment. The
former was dropped in v5.7.0-rc1~103 and thus we only support
VFIO. All other backends lead to an error (see
qemuBuildPCIHostdevDevProps(), or qemuBuildPCIHostdevDevStr() as
it used to be called in the era of aforementioned commit).

Might as well report the error in prepare phase and save hassle
of proceeding with device preparation (e.g. in case of hotplug
overriding the device's driver, setting seclabels, etc.).

2020c7e821 qemuxml2argvtest: Drop needless PCI backend setting
The qemuxml2argvtest does a bit of 'fixups' to parsed
virDomainDef just before generating the cmd line. For instance,
it sets PCI backend for hostdevs (to VFIO). The reason for this
is that we want to make the test host independent and thus
letting the code chose backend at runtime might render different
results on different machines. But this is not necessary, as
virpcimock (that the test uses) already creates a fake, but
stable environment (where /dev/vfio/vfio and IOMMU groups exist),
thus qemuHostdevHostSupportsPassthroughVFIO() returns true,
regardless of the actual host support.

3b87709c76 qemu: Move <hostdev/> PCI backend setting into qemuDomainPrepareHostdev()
virsh command domxml-to-native failed with below error but start
command succeed for same domain xml.

  "internal error: invalid PCI passthrough type 'default'"

If a <hostdev> PCI backend is not set in the XML, the supported
one is then chosen in qemuHostdevPreparePCIDevicesCheckSupport().
But this function is not called anywhere from
qemuConnectDomainXMLToNative(). But qemuDomainPrepareHostdev()
is. And it is also called from domain startup/hotplug code.
Therefore, move the backend setting to the common path and drop
qemuHostdevPreparePCIDevicesCheckSupport().

537d90437c lxc: Make lxcCreateHostdevDef() less versatile
Usually, we want a function to be as reusable as possible. But in
this specific case, when it's used just once we don't need that.
The lxcCreateHostdevDef() function is meant to create a hostdev.
The first argument selects the hostdev mode (caps/subsys) and the
second argument selects the type of hostdev (NET/STORAGE/MISC).
But because of how the function is written, it's impossible to
create a subsys hostdev as the function sets
hostdev->source.caps.type, regardless of mode. So the @mode
argument can be dropped.

Then, the function is called from one place and one place only.
And in there, VIR_DOMAIN_HOSTDEV_CAPS_TYPE_NET is passed for
@type so we can drop that argument too.

e98f0b99c0 qemuhotplugtest: Call qemuDomainUpdateDeviceLive() directly
There's no reason for qemuhotplugtest to reimplement which device
update function to call (testQemuHotplugUpdate()) when
qemuDomainUpdateDeviceLive() already does that. Thus, drop
testQemuHotplugUpdate() and call qemuDomainUpdateDeviceLive()

BTW: this also shows why reimplementing
qemuDomainUpdateDeviceLive() is bad idea: The
"disk-cdrom-nochange" test is succeeding only because
testQemuHotplugUpdate() supports graphics and returns an
(expected) error for every other devtype.

NB, there's still missing check that the resulting XML is the
expected one (just like we do for attach and detach), but that's
pre-existing and will be fixed later.

ac7f3667f2 meson: Work around configure_file(copy:true) deprecation
In our meson scripts, we use configure_file(copy:true) to copy
files from srcdir into builddir. However, as of meson-0.64.0,
this is deprecated [1] in favor of using:

  fs = import('fs')
  fs.copyfile(in, out)

Except, the submodule's new method wasn't introduced until
0.64.0. And since we can't bump the minimal meson version we
require, we have to work with both: new and old versions.

Now, the fun part: fs.copyfile() is not a drop in replacement as
it returns different type (a custom_target object). This is
incompatible with places where we store the configure_file()
retval in a variable to process it further.

While we could just replace 'copy:true' with a dummy
'configuration:...' (say 'configuration: configmake_conf') we
can't do that for binary files (like src/fonts/ or src/images/).

Therefore, places where we are not interested in the retval can
be switched to fs.copyfile() and places where we are interested
in the retval will just use a dummy 'configuration:'.

Except, src/network/meson.build. In here we not just copy the
file but also specify alternative install dir and that's not
something that fs.copyfile() can handle. Yet, using 'copy: true'
is viewed wrong [2].

383caddea1 qemu, ch: Move threads to cgroup dir before changing parameters
With cgroupv2 this has better effect on the resource allocation.  An
excerpt from Documentation/admin-guide/cgroup-v2.rst explains is this
way:

  Migrating a process across cgroups is a relatively expensive operation
  and stateful resources such as memory are not moved together with the
  process.  This is an explicit design decision as there often exist
  inherent trade-offs between migration and various hot paths in terms
  of synchronization cost.

  [...]

  Setting a non-empty value to "cpuset.mems" causes memory of
  tasks within the cgroup to be migrated to the designated nodes if
  they are currently using memory outside of the designated nodes.

d56ddd0d19 qemu: Check all watchdogs for iTCO duplicates
The loop initially skipped the first one because it was mainly checking
the incompatible actions, but was then modified to also check the
duplicity of iTCO watchdogs.

While at it change the type of the iteration variable to the usual size_t.
