On macOS when BROKEN_POLL is set in GLib, our tests will periodically
trigger a warning:
(process:50880): GLib-WARNING **: 02:54:15.272: poll(2) failed due to: Bad file descriptor.
Our code is inherantly racy, calling g_source_destroy which
removes the FD from the event thread poll asynchronously but
we close the FD immediately after g_source_destroy returns.
With poll() this results in POLLNVAL which we're ignoring, but
with select() it generates the BADF error on macOS.
We need to ignore the warnings on macOS to avoid abort()ing
our test programs.

Mostly the tests should fail cleanly, but sometimes the test might crash
or abort. In this case we'll need to know the stack traces in order to
debug the problem. Fortunately on the Cirrus CI macOS instances, the
crash reporting service is active and saving crashes to the directory
~/Library/Logs/DiagnosticReports/

These two pointers can never be NULL since they are initialised to a reference
of a struct. This became apparent when commit 210a195394 added a VIR_DEBUG
which used both pointers because due to the concise condition the compiler saw
that if the "and" part of the condition did short-circuit (and it assumed that
can happen) the second variable would not be initialised, but it is used in the
debugging message, so the build failed with:
In file included from ../src/cpu/cpu_x86.c:27:
../src/cpu/cpu_x86.c: In function ‘virCPUx86DataIsIdentical’:
../src/util/virlog.h:79:5: error: ‘bdata’ may be used uninitialized in this
function [-Werror=maybe-uninitialized]
Fix this by just assigning the helper pointers and remove the condition
altogether.

This patch adds 'version' parameter to generated XML API for functions

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.
