So we can more easily get any errors from attempting to write the file.
It is possible to get them with QFile, by either doing .flush() or using
QIODevice::Unbuffered, but using the C API is a definite sure way. Plus,
since this is QFileSystemEngine, this avoids the possibility that QFile
may choose to use a different file engine than the native one, for some
reason. And it reduces overhead.
This allows us to more easily detect why the file creation failed and
therefore stop looping if the error wasn't EEXIST. That will avoid an
infinite loop in case the necessary directories exist but aren't
writable.
It's also moved above the renaming, such that the failure to populate
the info file prevents the renaming too. Both operations can have the
same likely errors, ENOSPC and EIO. The likelihood of EIO is very low,
for both; but for ENOSPC it's far more likely for writing the
file. Avoiding the ENOSPC error for the renaming is handled in a later
commit.

If a move-to-trash operation failed, e.g. because the file was opened by
another process (or QFile), then the moveToTrash function would still
return true.
MSDN documents the IFileOperation::PerformOperations to return whether
the operation succeeded, but evidently this is only a statement about
the execution of queued up operations, not a statement about any of the
operations' success.
If the operation succeeded is reported by an HRESULT parameter
of the IFileOperationProgressSink::PostDeleteItem implementation,
and we ignored that parameter so far.
Check it via the SUCCEEDED macro, and set a boolean sink variable based
on that, which we can inspect to return the correct value.
Augment the test case by opening those files we create ourselves, and
if that fails (which it will on Windows, but not necessarily on other
platforms), then try again after closing the file. If the first attempt
succeeded, then the source file must also be gone.

We know that all lines from /proc/<PID>/maps end in a newline, so we
trim exactly that one byte, then we put it all back together with
.join('\n') to check if we've read the entire file.
Linux virtual files are usually served in 4 kB increments; tst_qfile's
maps file is about 16000 bytes for me, just short of the QIODevice buffer:
[pid 414315] read(5, "55c6afe04000-55c6afe11000 r--p 0"..., 16384) = 4049

It is not a coincidence that the reads are at line boundaries, though
it's not a guarantee from the kernel.

another process' /proc/<PID>/maps (hypothesis: QMU emulates the target

creeping in, and whitelist the affected TUs by #undef'ing
QT_NO_FOREACH locally, at the top of each file. For TUs that are part

ignore the signal block and terminate the application -- Darwin appears
