0f3cedc676 domain_conf: make virDomainPostParseCheckISCSIPath() void
The function only returns zero or aborts, so it might as well be void.

247460ab41 util: hash: Use virHashForEachSafe in places which might delete the element
Convert all calls to virHashForEach where it's not obvious that the
callback is _not_ deleting the current element from the hash to
virHashForEachSafe which will be deemed safe to do such operation.

Now that no iterator used with virHashForEach deletes current element we
can document that virHashForEach must not touch the hash table in any
way.

4eb8e9ae8b util: hash: Rewrite sorting of elements in virHashGetItems
All but one of the callers either use the list in arbitrary order or
sorted by key. Rewrite the function so that it supports sorting by key
natively and make it return the element count. This in turn allows to
rewrite the only caller to sort by value internally.

This allows to remove multiple sorting functions which were sorting by
key and the function will be also later reused for some hash operations
internally.

85c8c29214 remove unnecessary cleanup labels and unused return variables
After converting all DIR* to g_autoptr(DIR), many cleanup: labels
ended up just having "return ret", and every place that set ret would
just immediately goto cleanup. Remove the cleanup label and its
return, and just return the set value immediately, thus eliminating

7f42bdf5c0 util: manually set dirp to NULL after closing in virCapabilitiesInitCache()
In all uses of VIR_DIR_CLOSE() except one, the DIR* is never
referenced after closing all the way until it goes out of
scope. virCapabilitiesInitCaches(), however, reuses the same DIR* over
and over in a loop, but due to having many error conditions that
result in a goto out of the loop, it's not well suited to reducing the
scope of the variable until we introduce a g_autoptr cleanup function
for DIR*.

In preparation for doing just that, we need to get rid of the side
effect of VIR_DIR_CLOSE() setting the DIR* to NULL, so in this one
case, let's manually set the DIR* to NULL. Then in an upcoming patch
we can safely remove the side effect from VIR_DIR_CLOSE().

This extra/ugly bit of code is only temporary: once we introduce the
g_autoptr cleanup function for DIR*, we will remove this manual
close/clear completely anyway.

53aec799fa Include vdpa devices in node device list
The current udev node device driver ignores all events related to vdpa
devices. Since libvirt now supports vDPA network devices, include these
devices in the device list.

Example output:

virsh # nodedev-list
[...ommitted long list of nodedevs...]
vdpa_vdpa0

virsh # nodedev-dumpxml vdpa_vdpa0
<device>
  <name>vdpa_vdpa0</name>
  <path>/sys/devices/vdpa0</path>
  <parent>computer</parent>
  <driver>
    <name>vhost_vdpa</name>
  </driver>
  <capability type='vdpa'>
    <chardev>/dev/vhost-vdpa-0</chardev>
  </capability>
</device>

NOTE: normally the 'parent' would be a PCI device instead of 'computer',
but this example output is from the vdpa_sim kernel module, so it
doesn't have a normal parent device.

08f8fd8413 conf: Add support for vDPA network devices
This patch adds new schema and adds support for parsing and formatting
domain configurations that include vdpa devices.

vDPA network devices allow high-performance networking in a virtual
machine by providing a wire-speed data path. These devices require a
vendor-specific host driver but the data path follows the virtio
specification.

When a device on the host is bound to an appropriate vendor-specific
driver, it will create a chardev on the host at e.g.  /dev/vhost-vdpa-0.
That chardev path can then be used to define a new interface with
type='vdpa'.

2508d10f67 conf: domain: sev: Make 'cbitpos' & 'reducedPhysBits' attrs optional
These XML attributes have been mandatory since the introduction of SEV
support to libvirt. This design decision was based on QEMU's
requirement for these to be mandatory for migration purposes, as
differences in these values across platforms must result in the
pre-migration checks failing (not that migration with SEV works at the
time of this patch).

Expecting the user to specify these is cumbersome and the same XML
cannot be re-used across different revisions of SEV. Since
we have SEV platform information saved in QEMU capabilities, we can
make the attributes optional and should fill them in automatically
in the QEMU driver right before starting it.
