8603b3d76c tools: add '--xpath EXPRESSION --wrap' args to all dumpxml commands
While you can chain the virsh output up to a later 'xmllint' or 'xpath'
command, integrating it into virsh avoids needs for installing extra
binaries which we've often found to be missing on production installs
of libvirt. It also gives better response if the initial virsh command
hits an error, as you don't get an aborted pipeline.

    $ virsh pool-dumpxml --xpath //permissions default
    <permissions>
      <mode>0711</mode>
      <owner>1000</owner>
      <group>1000</group>
      <label>unconfined_u:object_r:svirt_home_t:s0</label>
    </permissions>

If multiple nodes match, they are emitted individually:

    $ virsh dumpxml --xpath '//devices/*/address[@type="pci"]' --wrap demo
    <address type="pci" domain="0x0000" bus="0x05" slot="0x00" function="0x0"/>
    <address type="pci" domain="0x0000" bus="0x03" slot="0x00" function="0x0"/>
    ...snip...
    <address type="pci" domain="0x0000" bus="0x00" slot="0x02" function="0x0" multifunction="on"/>
    <address type="pci" domain="0x0000" bus="0x07" slot="0x00" function="0x0"/>

but if intending to post-process the output further, the results
can be wrapped in a parent node

    $ virsh dumpxml --xpath '//devices/*/address[@type="pci"]' --wrap demo
    <nodes>
      <address type="pci" domain="0x0000" bus="0x05" slot="0x00" function="0x0"/>
      <address type="pci" domain="0x0000" bus="0x03" slot="0x00" function="0x0"/>
      ...snip...
      <address type="pci" domain="0x0000" bus="0x00" slot="0x02" function="0x0" multifunction="on"/>
      <address type="pci" domain="0x0000" bus="0x07" slot="0x00" function="0x0"/>
    </nodes>

8615c19b5d tools: add helper method for printing an XML document
The trivial case of fully printing an XML document is boring, but
this helper does more by allowing an XPath expression to be given.
It will then print just the subset of nodes which match the
expression. It either print each match as a standalone XML doc
or can put them into one new XML doc wrapped woith <nodes>...</nodes>

2177de7b6e virsh: Check whether enough arguments was passed to iothreadset
Virsh has iothreadset command which allows setting various
attributes of IOThreads. However, when the command is called
without any arguments (besides domain and IOThread IDs), then
@params stays NULL and is passed to virDomainSetIOThreadParams()
which produces rather user unfriendly error message:

  error: params in virDomainSetIOThreadParams must not be NULL

Introduce a check and produce better error message.

7f463b4c0d nss: Compare hostname case insensitive
There are some tools that convert hostname to lowercase before
resolving it (e.g. ssh). In a way it makes sense because DNS is
case insensitive and in case of ssh the lowercase version is then
used to find matching record in its config file. However, our NSS
module performs case sensitive comparison, which makes it useless
with ssh. Just consider a machine named FooBar.

Therefore, switch to case insensitive string comparison.

bf213aa965 virsh: report the D-Bus bus URI for domdisplay
This implementation reports only Unix bus address using the URI format
proposed in https://gitlab.freedesktop.org/dbus/dbus/-/issues/348.

We prefer a URI form over the D-Bus address form, since all other
display protocols use a URI, allowing to distinguish between protocols
and making client implementation simpler.

Other transports (for example TCP) are not yet handled.

The client is assumed to know what to lookup on the bus (the bus name,
path & interface of the VM, eventually matching its UUID)

P2P mode doesn't report any available URI.

9223ebbc85 virsh: cmdBlockcopy: Fix generator of block copy disk XML
In a recent commit I've attempted to rewrite the XML generator to use
virXMLFormatElement instead of manual steps. Unfortunately the commit
had multiple problems resulting in a garbled XML:

1) in certain cases the wrong buffer was used resulting in misplaced
   snippets
2) the child element buffer was improperly set up so sub-elements were
   not indented

This resulted in following XML being generated:

 $ virsh blockcopy cd vda /tmp/test.copy --raw --print-xml
 type='file''/tmp/test.copy'/>
 <driver type='raw'/>
 <disk>
 <source file=</disk>

To fix this we'll generate the '<source>' element in one go and use the
proper buffer for it and other places.

b94239a61e meson: Use dicts to initialize cfg_data objects
Instead of creating an empty object and then setting keys one
at a time, it is possible to pass a dict object to
configuration_data(). This is nicer because it doesn't require
repeating the name of the cfg_data object over and over.

There is one exception: the 'conf' object, where we store values
that are used directly by C code. In that case, using a dict
object is not feasible for two reasons: first of all, replacing
the set_quoted() calls would result in awkward code with a lot
of calls to format(); moreover, since code that modifies it is
sprinkled all over the place, refactoring it would probably
make things more complicated rather than simpler.

d5f81479a6 virsh: Fix integer overflow in allocpages
I've came across an aarch64 system which supports hugepages up to
16GiB of size. However, I was unable to allocate them using
virsh allocpages. This is because cmdAllocpages() uses
vshCommandOptScaledInt(), which scales passed value into bytes,
but since the virNodeAllocPages() expects size in KiB the
variable holding bytes is then divided by 1024. However, the
limit for the biggest value passed to vshCommandOptScaledInt() is
UINT_MAX which is now obviously wrong, as it needs to be UINT_MAX
* 1024.

The same bug is in completer. But here, let's use ULLONG_MAX so
that we don't have to care about it anymore.

c7dca225e5 virsh: cmdDesc: Fix logic when '-edit' is used along with 'desc' argument
Historically the use of the '-desc' multiple argument parameter was not
forbidden toghether with '-edit', but use of both together has some
unexpected behaviour. Specifically the editor is filled with the
contents passed via '-desc' but if the user doesn't change the text in
any way virsh will claim that the description was not chaged even if it
differs from the currently set description. Similarly, when the user
would edit the description provided via 'desc' so that it's identical
with the one configured for the domain, virsh would claim that it was
updated:

  # virsh desc cd
  No description for domain: cd
  # EDITOR=true virsh desc cd --edit "test desc"
  Domain description not changed

After the fix:

  # virsh desc cd
  No description for domain: cd
  # EDITOR=true virsh desc cd --edit "test desc"
  Domain description updated successfully
  # EDITOR=true virsh desc cd --edit "test desc"
  Domain description not changed
