Use the 'parent' axis to check whether the parent is a div with
class='section' rather than looking for 'toc-backref' anchor to see
whether to generate one of the headerlink alternatives. Both hare
docutils-specific thus apply to docs generated from RST documents.
This adds the links for pages generated from RST documents which don't
have a table of contents (and thus lack the 'toc-backref' anchors) and
thus fixes pages such as hacking.html and news.html to have reasonable
links which can be shared.

GLibC has a really complicated way of dealing with the 'stat' function
historically, which means our mocks in turn have to look at four
different possible functions to replace, stat, stat64, __xstat,
__xstat64.
In Fedora 33 and earlier:
- libvirt.so links to __xstat64
- libc.so library exports stat, stat64, __xstat, __xstat64
- sys/stat.h header exposes stat and __xstat
In Fedora 34 rawhide:
- libvirt.so links to stat64
- libc.so library exports stat, stat64, __xstat, __xstat64
- sys/stat.h header exposes stat
Historically we only looked at the exported symbols from libc.so to
decide which to mock.
In F34 though we must not consider __xstat / __xstat64 though because
they only existance for binary compatibility. Newly built binaries
won't reference them.
Thus we must introduce a header file check into our logic for deciding
which symbol to mock. We must ignore the __xstat / __xstat64 symbols
if they don't appear in the sys/stat.h header, even if they appear
in libc.so

The %meson macro sets "--auto-features=enabled", thus any feature in the
RPM which has a "with_XXX" condition, needs to explicitly pass a
"-DXXX=state" arg to %meson to override the auto features setting.
The with_libssh and with_libssh2 conditions were not exposed to meson,
so if either was set disabled, then meson would fail the build if the

We use the capability to switch to using 'block-export-add' in the
upcoming qemu release instead of the at the same time deprecated
'nbd-server-add'.
Unfortunately qemu wants to change the interface of 'block-export-add'
before the release. Since we've tried to stay up to date and added the
code before it was written in stone, we need to disable the use of the
new interface for the upcoming libvirt release so that we don't have a
version of libvirt which would not work with the upcoming qemu version.
Remove the detection of 'block-export-add' until we are more sure how
the qemu interface will look.

The cpu mask was free()'d immediately on any error and at the end of the
function, where it was expected that it would either error out and return or
goto another allocation if the code was to fail. However since commit
9514e24984 the error path did not return in one new case which caused
double-free in such situation. In order to make the code more straightforward
just free the mask after it's been used even before checking the return code of
the call.

In recent commit v6.8.0-135-g518be41aaa the formatting of NBD
into migration cookie was moved into a separate function and with
it it was switched from direct printing into the output buffer to
virXMLFormatElement(). But there was a typo. The
virXMLFormatElement() accepts two buffers on input, one for
element attributes and another for child elements. Well, the line
that was supposed to add NBD port into the attributes buffer
printed the attribute directly into the output buffer which
produced this mangled XML:
<qemu-migration>
port='49153'<nbd>
<disk target='vda' capacity='8589934592'/>
<disk target='vdb' capacity='12746752000'/>
</nbd>
</qemu-migration>
Changing the incriminated line to print into the attributes
buffer fixes the problem.

In one of recent patches the way that we start NBD server for
incoming migration was reworked (v6.8.0-rc1~298). A new boolean
was introduced that tracks whether the NBD server was started so
that we don't start it twice nor record in the port in the port
allocator twice. Well, this idea is good, but in the
implementation the boolean is never set, so we are reserving the
port twice and would be starting the NBD server twice too if it
wasn't for port reservation fail.

but this example output is from the vdpa_sim kernel module, so it
