Move QGLWidget::setContext logic into QEgl & QGLContext

QEgl::createSurface() on X11 will now check to see if the device's
X11 Visual is compatible with the EGLConfig passed in. If it is not
compatible, the function will re-create the QPaintDevice's native
drawable with a different Visual (one which is compatable with the
EGLConfig). This represented the bulk of the QGLWidget::setContext
method which is now much simpler.

As a consequense of this change, QWidgets with graphicssystem opengl
will behave much more like QGLWidget as most of the code is re-used.
So things like WA_TranslucentBackground should now work with opengl
graphicssystem too.
