The "dist" and "test" targets in ninja end up calling back into
the equivalent meson commands. The meson commands support various
arguments that are not accessible when invoked via ninja, so it
is preferrable to use meson directly.

"meson test" will only print a list of which tests fail by default,
so we were sending the full test log to stdout on failure. This makes
it really hard to see the errors though as the test log has all
succcesful tests too.
"ninja test" will print the same as "meson test", following by details
of each failure.
It does this using the "--print-errorlog" flag, so lets use that in
the codestyle job.

This is a rewrite of:
https://wiki.libvirt.org/page/Live-disk-backup-with-active-blockcommit
Once this commit merges, the above wiki should point to this kbase
document.
NB: I've intentionally left out the example for pull-based full backups.
I'll tackle it once QMP `x-blockdev-reopen` comes out of experimental
mode in upstream QEMU. Then pull-based can be described for both full
and and differntial backups.
Overall, future documents should cover:
- full backups using both push- and pull-mode
- differential backups using both push- and pull-mode

What this function really does it takes ownership of all pointers
passed (well, except for the first one - caps - to which it

double pointers to make the ownership transfer obvious.

The securityselinuxhelper is a mock that's replacing libselinux
APIs with our own implementation to achieve deterministic
results. Our implementation uses env vars (among other things) to
hold internal state. For instance, "FAKE_SELINUX_CONTEXT" and
"FAKE_SELINUX_DISABLED" variables are used. However, as we were
switching from setenv() to g_setenv() we also changed the set of
possible retvals from setcon_raw() and security_disable().
Previously, the retval of setenv() was used directly which
returns 0 on success and -1 on error. But g_setenv() has
different retval semantics: it returns 1 on success and 0 on
error.
This discrepancy can be observed by running viridentitytest where
case #2 reports an error ("!") - because setcon_raw() returns 1.

Since its introduction in v0.9.1~65 the virOnce() was expected to
follow the usual retval logic (0 for success, a negative number
for failure). However, that was never the case.
On the other hand, looking into glibc and musl the pthread_once()
never returns anything other than zero (uclibc-ng seems to not
implement pthread_once()), therefore we never really hit any
problem. But for code cleanliness (and to match POSIX
documentation), let's change to code so that our retval logic is
honoured.

This is done by adding a @defaultResult argument to virXMLPropInt since

In certain cases such as in virDomainControllerDefParseXML we pass the

if unused while preserving the existing functionality of keeping the
previous value.
