Since each .arg() call starts from scratch, a file name containing a
suitable %n would mess up the formatting of the following .arg() call.
Fix by using multiArg(), which requires to pre-format the line into a
QString, but which performs only a single-pass, so doesn't suffer from
the placeholder injection problem that plagues .arg()-chaining.

[ChangeLog][Important Behavior Changes] QTextStream streams char16_t's

as ushort or int, and stream that. This is backwards-compatible.

The os_log_create API documents that the logging subsystem will
maintain a global list of logs, and will return existing logs
for subsequent calls for the same category and subsystem, so
we don't need to maintain our own log.
This also avoids a crash were we would end up in the logging
backend during application shutdown, when destructor functions
run, for example via QLibraryStore::cleanup().
In this case local static such as our log cache had already been
destroyed, leading to use after free.

This loop here was a lonesome instance of a CAS loop in which adding
_mm_pause() was simple, because the code didn't use the usual pattern
do {
construct new value
} while (!testAndSet)
we use everywhere else in Qt.
In search of an elegant pattern that would allow to apply
qYieldCpu()/_mm_pause() to those idiomatic CAS loops, too, I've
reached for a lambda to construct the new value. This should apply to
all (tight) CAS loops, and may form the basis of an API extension
whereby we take that lambda as a function argument to encapsulate the
CAS loop in an algorithm (a function).
