The font caches can only be used from a single thread at a time.
QFontEngineFT for instance, uses a global static thread storage
which is accessed on releasing and creating engines, and this
causes a crash if the font engine is created on one thread and
released on another.

We use the updatePolish() function to make sure the caches are
empty before entering updatePaintNode(), and then we invalidate
the cache again after updatePaintNode() is done.

In updateSize() we were trying to force relayouts for RichText
when the width changes by always setting widthExceeded to true.
But further down in the same function, we overwrote this
with textWidth() < idealWidth(), which doesn't work, because
both properties are the wrapped width of the document and
should only differ if the text cannot be wrapped properly.

The result was that when increasing the width of a Text element,
we would hit the optimization and skip the relayout.

[ChangeLog][Text] Fixed Text with the RichText format to
correctly update wrapping when the width of the element grows.

valid on retina displays as well, so having the setter second-guess

See the task for the full reasoning behind this patch.

The threaded renderloop has been refactored to have one window per
thread. This is mostly a simplification of the current code path where
for loops over multiple windows are turned into if (window).

The QSGContext has been split into two classes, QSGRenderContext
for which there is one per OpenGLContext.

The rest of the patch is name changes and a couple of cleanups
in the hopes of simplifying this change.
