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).

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"/>

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 *'.

Missing semicolon at the end of macros can confuse some analyzers
(like cppcheck <filename>), and we have a mix of semicolon and
non-semicolon usage through the code. Let's standardize on using
a semicolon for VIR_ENUM_IMPL calls.
Move the verify() statement to the end of the macro and drop
the semicolon, so the compiler will require callers to add a
semicolon.
While we are touching these call sites, standardize on putting
the closing parenth on its own line, as discussed here:

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.
