After fixing the data type for D24S8, we can now implement attaching
depth and stencil (with the same texture).
For Metal we need to set a stencil flag correctly.
This allows using D24S8 in the manual test, which is likely the format
that is going to be commonly used when setting up multiview with
Qt Quick.

Cannot just do like with other APIs and expose a view of multiple
array layers. The only option is to use the multiview-specific API
and specify layers 0..view_count-1 in the depth texture.
This allows having depth in a multiview render pass with OpenGL.
Note that this does not cover stencil. D24S8 does not work, so
we may need to explore having a dedicated, separate stencil
texture.

This is similar to and extends the prevention of thread cancellation
introduced by commit ba05af82d3. This
prevents the situation in which a signal gets delivered (usually because
of a crash) and the parent process' handler is run, doing things it
shouldn't between vfork() and execve().
Most C libraries (all that I've investigated) unblock SIGABRT on
abort(), so this doesn't affect them. Likewise, on most OSes, crashes
ignore the signal block and terminate the application -- Darwin appears
to be an exception, but vfork() is not enabled there. Both situations
are tested by terminateInChildProcessModifier().

There are two temporaries, reply.arguments() returns a temporary QList
and list.at(0) returns a temporary reference to the first element. The
local reference variable would only extend the lifetime of the temporary
object it's bound to, list.at(0), but not the temporary list itself.
Even though this a false positive in this case because QList is
implicilty shared, the compiler can't tell the difference and the fix is
simple.

So no-one 'fixes' the test by pinning synchronizer.futures() into a

This fixes a crash while parsing an XML file with garbage data, the file
starts with '<' then garbage data:
- The loop in the parse() keeps iterating until it hits "case 262:",
which calls fastScanName()
- fastScanName() iterates over the text buffer scanning for the
attribute name (e.g. "xml:lang"), until it finds ':'
- Consider a Value val, fastScanName() is called on it, it would set
val.prefix to a number > val.len, then it would hit the 4096 condition
and return (returned 0, now it returns the equivalent of
std::null_opt), which means that val.len doesn't get modified, making
it smaller than val.prefix
- The code would try constructing an XmlStringRef with negative length,
which would hit an assert in one of QStringView's constructors
Add an assert to the XmlStringRef constructor.
Add unittest based on the file from the bug report.
Later on I will replace FastScanNameResult with std::optional<qsizetype>
(std::optional is C++17, which isn't required by Qt 5.15, and we want to
backport this fix).

This minimizes any multi-threading / file-locking issues as the file is
closed once the contents are read.
This change assumes /proc/self/mountinfo is available on Linux systems,
and doesn't fallback to setmntent(). It's been around since at least
Linux Kernel 2.4.0.
This requires exporting qstrntoll() for the unittests (using
QT_AUTOTEST_EXPORT and wrapping the those unittests in "#ifdef
QT_BUILD_INTERNAL"), otherwise linking fails.

The basic feature, with 2 views going to a texture array's
0 and 1 elements, seems to be working with macOS, also with
MSAA. Instanced drawing has not been verified. (relevant
because layered rendering works via instancing in Metal
and the QRhi backend has to adjust the instance count
in every draw call)
