Log:

Branch libmythui-osd: Add MythRenderOpenGL as a new general purpose
OpenGL context which will replace OpenGLContext for rendering both UI
elements and video.

This is largely a lift and shift of the code from OpenGLContext into a
sub-class of QGLContext with additional functionality for the UI
rendering aspects. This gives us Qt cross-platform support out of the
box (with the exception of some screen information) and hence greatly
simplifies the code base. The downside is that we must use a QGLWidget
for rendering, it is not yet thread safe under X11 (as we do not have
access to the underlying X display connection) and, for the time being
at least, there is no OpenGL vsync support.

As yet untested on OS X and windows.
