Laszlo Agocs 1e18df9c73 Extend QOpenGLFunctions with GL1 functions
This introduces the ability to indirectly invoke all common GL1-GLES2
functions via QOpenGLFunctions. The GL1 functions are not yet resolved,
since this would not work anyway when linking to an OpenGL implementation
directly. However this may change later but that will be a completely
internal change without affecting any public APIs.

Also migrate some of the opengl examples to use QOpenGLFunctions for
everything. Once dynamic GL loading becomes available on some platforms,
these examples should continue to function without any changes since they
do not anymore invoke any OpenGL functions directly.
