Added explicit threading API to QtOpenGL.
Since QtOpenGL/QGLContext is implemented in terms of QtGui/QOpenGLContext which has stricter requirements about how it's supposed to be used, we need to apply these requirements to QGLContext as well. This change adds QGLContext::moveToThread(QThread *) and documents it as a necessity for making a context current on another thread. Also introduces QGLPixelbuffer::context() to access the QGLContext of a pixelbuffer, and made QGLWidget::context() return a non-const QGLContext, since there's no good reason why it shouldn't, and it leads to less const_cast clutter. We could have introduced a backdoor in QOpenGLContext instead, making it loosen its requirements, but that would have made it harder / impossible to fully support threaded OpenGL in all the platforms.
