e90d48ae6e virsh: Require --xpath for *dumpxml
Historically, the dumpxml command reject any unknown arguments,
for instance:

    virsh dumpxml fedora xxx

However, after v8.5.0-rc1~31 the second argument ('xxx') is
treated as an XPath, but it's not that clearly visible.
Therefore, require the --xpath switch, like this:

    virsh dumpxml fedora --xpath xxx

Yes, this breaks already released virsh, but I think we can argue
that the pool of users of this particular function is very small.
We also document the argument being mandatory:

   dumpxml [--inactive] [--security-info] [--update-cpu] [--migratable]
           [--xpath EXPRESSION] [--wrap] domain

The sooner we do this change, the better.

The same applies for other *dumpxml functions (net-dumpxml,
pool-dumpxml, vol-dumpxl to name a few).

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>

071bab399a virsh: Introduce virshCompleteEmpty and use it for places where we can't suggest anything
For now this serves just as an annotation because readline and also the
bash completion script insist on completing local paths when an empty
list is returned.

This will serve for future reference once we'll be able to properly
refuse to suggest anything.

The completer is used for fields such as names for new objects,
description strings, password strings etc, URIs and hostnames which we
can't feasibly autocomplete.

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

Missing semicolon at the end of macros can confuse some analyzers

Move the verify() statement to the end of the macro and drop

semicolon.

While we are touching these call sites, standardize on putting

8fe09a5317 virsh: fixing segfault by pool autocompleter function.
The commands which requires a pool to perform any action for a volume is
throwing a segfault when you pass the volume name before a pool name or
without the argument '--pool'.

An example that works:
virsh # vol-list loops-pool
 Name                 Path
-------------------------------------------------------------------
 loop0                /mnt/loop0

virsh # vol-info --pool loops-pool lo<TAB>

An example that does not work:
virsh # vol-list loops-pool
 Name                 Path
-------------------------------------------------------------------
 loop0                /mnt/loop0

virsh # vol-info lo<TAB>
Segmentation Fault

The example 'vol-info' can be executed as 'vol-info loop0 --pool
loops-pool'. So, this commit fixes this problem when the arguments are
inverted and avoids the segfault.
