Merge branch '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-2 into 4.7-integration

* '4.7' of scm.dev.nokia.troll.no:qt/oslo-staging-2:
  Allow to build Qt in static with mingw
  Protected call to glXChooseFBConfig with appropriate defines.
  Use the new OpenGL 3.* context/profile if asked with X11/GLX.
  Splitted attrib_list generation into buildSpec from QGLContext::tryVisual.
  Fix QTransform::map(const QPainterPath &) not working with paths that
