We accept TPM version in the domain XML. However, supported
version depends on the host (swtpm_setup binary) and thus it may
be tricky for users (or mgmt applications) chose a version.
Introduce machinery for reporting supported version in domain
capabilities.

Surprisingly, we don't document TPM part of domain capabilities.
Fortunately, the information exposed is pretty much self

When using runtime setting of logging with 'virt-admin' it can be
confusing that the settings are discarded when the shutdown timeout of a
daemon is reached.
Add a note about this behaviour along with a suggestion to use
virt-admin to disable the behaviour if needed.

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"/>
