Added QGLPixelBuffer implementation using framebuffer objects.

Instead of having QGLPixelBuffer be a unusable stub implementation we
deprecate it and implement it in terms of QOpenGLFramebufferObject.
Framebuffer objects are anyway the recommended replacement for
pixelbuffers in modern OpenGL, as the context switching overhead is
avoided.
