Fully expand entities to ensure deep or widely nested ones fail parsing

With 46a8885ae486e238a39efa5119c2714f328b08e4, we failed when parsing
entities whose partially expanded size was greater than 1024
characters. That was not enough, so now we fully expand all entities.

iOS: Flesh out device-pixel-ratio handling in QIOSWindow

We don't need to cache the device-pixel-ratio, as we can ask the UIView
directly. We do need to set it though, as the default behavior of
matching the screen scale does not apply for EAGL-backed views,
but the ratio needs to match the current screen the view is on.

iOS: Tie QIOSContext FBOs to corresponding QPlatformWindow, not QWindow

A QWindow may be created() and destroyed() multiple times in the lifetime
of the window, each time resulting in a new platform window (QIOSWindow)
being created. This QIOSWindow is backed by a new UIView each time, hence
it needs a new FBO and renderbuffer-mapping, since the previous
renderbuffer was mapped to the old UIView.

This fixes a bug where a QWindow would not render after a destroy()
unless it was resized (which triggered new FBO/renderbuffers).

We need to inherit QObject so that we can watch the destroyed() signal.

iOS: Enable clipping of subviews when QWindow has child windows

QWindow::setParent() is documented to imply that the geometry of the
window is in the parent's coordinate system and that the window is
clipped to the parent.

Instead of always enabling clipping of subviews for our UIView subclass
we dynamically detect if we have QWindow children and enable/disable it
on the fly.

QOpenGLPixelTransferOptions: declare as shared, add move assignment operator

A move constructor cannot be added because the class uses
a smart pointer to hold its pImpl, so the move ctor would
have to be out-of-line, destroying BC between C++11 and C++98
versions of Qt.

Member-swap is required for Q_DECLARED_SHARED, which in turn
enables efficient use of the class in Qt containers by marking
it movable.

Detect architecture before auto detection

Some compile checks may depend on the architecture,
e.g., NEON is only available for ARM, so it makes no
sense to check it for this architecture. Therefore
we need to run the architecture check before we

support a cache that is really just a cache

unlike .qmake.cache & co., the presence of this file has no magic
effects on where mkspecs, modules and other things are searched.

as the obvious name "cache" is of course already taken, we call it
"stash".

the file is searched up to the super cache (if present), otherwise up to
the normal cache/conf (if present), otherwise up to the root.
if it's not found, it is created next to the super cache (if present),
otherwise next to the cache/conf (if present), otherwise in the current
output directory.

note that the cache really should be created and populated by the
top-level project if there are subprojects: otherwise, if there is an
"anchor" (super/cache/conf), subprojects would race for updating the
cache and make a mess. without an "anchor", each subproject would just
create its own cache, kind of defeating its purpose. this is no
different from the existing "cache", but it's worth mentioning that
removing the "anchoring" function does not remove the "nesting order"
constraint.
