[cogl] Adds cogl_read_pixels to replace direct use of glReadPixels

Browse Source 
To allow for flushing of batched geometry within Cogl we can't support users
directly calling glReadPixels.  glReadPixels is also awkward, not least
because it returns upside down image data.

All the unit tests have been swithed over and clutter_stage_read_pixels now
sits on top of this too.
