Introduce a simple helper fetching a sub-element node by name. This is
meant as a simple replacement for either open-coded versions of this or
use of XPath for this trivial lookup.

The XPath lookup guarantees that the top level element is always 'disk'
so there's no need to check that it actually is. We can also remove the
two unnecessary temporary variables.

In two instances (qemuMonitorJSONGetStringListProperty,

Rather than checking that the object has the correct key and then

Additionally we can avoid the conversion if there are no members

The 'dependencies' field in the return data may be missing in some
cases. Historically 'virJSONValueObjectGetStringArray' didn't report
error in such case, but later refactor (commit 043b50b948 ) added
an error in order to use it in other places too.
Unfortunately this results in the error log being spammed with an
irrelevant error in case when qemuAgentGetDisks is invoked on a VM
running windows.
Replace the use of virJSONValueObjectGetStringArray by fetching the
array first and calling virJSONValueArrayToStringList only when we have
an array.

Introduce virJSONValueArrayToStringList which does only the conversion
from an array to a stringlist.
This will allow refactoring the callers to be more careful in case when
they want to handle the existance of the member in the parent object

Historically our migration APIs declare 'unsigned long flags'. Since
it's baked into our API we can't change that but we can avoid
compatibility problems by preemptively refusing the extra range on
certain arches to prevent future surprise.

exceed the range of 'unsigned int'.

In one of recent commits I've introduced a new test case to
commandtest. In the test case I'm using poll() to wait for data
on a pipe (the write end is passed to commandhelper). However, on
FreeBSD the POLLIN semantic is a bit different:
POLLIN Data other than high priority data may be read
without blocking.
Well, the pipe is non-blocking, so even if there's no data to be
read the flag is set (and subsequent read() returns 0). On the
other hand, POLLHUP is set too, BUT, if the commandhelper manages
to write everything into the pipe and die right after we'd get
both POLLIN and POLLHUP after the very first time poll() returns.
That's very unfortunate, but okay - we can just check whether
read() returned zero and break from the reading loop.

Instead of using:

virTestDifference(stderr, a, b);
...
}
we can use:
if (virTestCompareToString(a, b) < ) {
...

Generated by the following spatch:

expression a, b;

- if (STRNEQ(a, b)) {

and its variations (STRNEQ_NULLABLE() instead of STRNEQ(), then
in some cases variables passed to STRNEQ() are in reversed order
when compared to virTestCompareToString()).
However, coccinelle failed to recognize the pattern in
testNWFilterEBIPTablesAllTeardown() so I had to fix it manually.
Also, I manually fixed testFormat() in tests/sockettest.c as I
didn't bother writing another spatch rule just for that.

Two things are happening here:
1) Call to virTestDifference() is guarded by '!result ||
STRNEQ(result, _)' check. This is suboptimal since we have
STRNEQ_NULLABLE().
2) There are couple of VIR_TEST_DEBUG() printings, which are
useless. If debug is off they don't print anything, and if it
is on, then much more information is printed by subsequent
virTestDifference().
This makes the STRNEQ() + virTestDifference() combo look similar
to the rest of tests and thus can be picked up by spatch later.
