AMD cpus report Core (compute unit) identifiers of the cpu running the

In case when the 'KVM_GET_SUPPORTED_CPUID' ioctl on /dev/kvm would
fail for other reason than the documented E2BIG, our code would continue
looping and calling it while always increasing the memory buffer even
when that will not help.
Rewrite the function to allow another iteration only with the correct
errno.
Additionally rename the 'i' variable to 'alloc_size' as it's not a pure

The function returns 'virCPUData' but doesn't do two important steps
which other code takes:
1) leaves with all-zero data is stripped from the XML output
2) the data is expected to be sorted in the array
Now the 'virHostCPUGetCPUID' helper returns both all 0 leaves and
doesn't order them as we expect.
If this is then used in conjunction with 'virCPUx86DataIsIdentical'
together with data which made a roundtrip to XML and back the result
will be always false even if the data itself is identical.

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.

virConnectAuthPtrDefault is the only variable that we export and
with the documentation being at the C file, it makes harder to find

With this patch, the documentation of this variable can be found by
those who look at the header file for guidance plus, it will also be
included in the XML API, as the followup patch will fix apibuild.py
to store what is documented in the header file for this variable.
Note that the apibuild, does not do the same with .c files. It'd
require adding it for (parsing) recursion, similar to what is done
for functions. Considering the pros/cons, seems more reasonable to
move the docstring to the header file instead.

This is a quite an old (created at 2016) patch fixing an issue for at
that time contemporary Fedora 23. virsh reboot returns success (yet
after hanging for a while), VM is rebooted sucessfully too but then
shutdown from inside guest causes reboot and not shutdown.
VM has agent installed. So virsh reboot first tries to reboot VM thru
the agent. The agent calls 'shutdown -r' command. Typically it returns
instantly but on this distro for some reason it takes time. I did not
investigate the cause but the command waits in dbus client code,
probably waits for reply. The libvirt waits 60s for agent command to
execute and then errors out. Next reboot API falls back to ACPI shutdown
which returns successfully thus the reboot command return success too.
Yet shutdown command in guest eventually successfull and guest is truly
rebooted. So libvirt does not receive SHUTDOWN event and fake reboot
flag which is armed on fallback path stays armed. Thus next shutdown
from guest leads to reboot.
The issue has 100% repro on Fedora 23. On modern distros I can't
reproduce it at all. Shutdown command is asynchronous and returns
immediately even if I start some service that ignores TERM signal and
thus shutdown procedure waits for 90s (if I not mistaken) before sending
KILL.
Yet I guess it is nice to have this patch to be more robust.
