Added QOffscreenSurface class.
Inherits QSurface and allows to use OpenGL from an arbitrary thread.
Platform plugins can implement QPlatformOffscreenSurface, otherwise an
invisible QWindow is used by QOffscreenSurface.
This patch includes an implementation of QOffscreenSurface for XCB
and EglFS platform plugins using pbuffers.
