Using freeglut, the MAIN-LOOP does exit at some point but
*GLUT-INITIALIZED-P* does not reflect that. So let's use
(GETP :INIT-STATE) again to check for such cases.

Use 1.0s0 so that cl-opengl compilation is not dependent on
*READ-DEFAULT-FLOAT-FORMAT* being bound to SINGLE-FLOAT.

Added support for the following glu functions:
    gluQuadOrientation
    gluQuadTexture
    gluQuadNormals
Also defined the C structures needed for these functions.
Set all three of the above to be exported.
Added the glu Sphere function to the export list.

- in gl:tex-parameter's :texture-border-color use "elt" rather than
  "aref", to be consistent with other calls in the file
- in gl:fog, implement :fog-color
- change names of some gluPerspective parameters to match their standard
  names

Initial handling for type Int64EXT from the gl spec files. If this is the correct path, :int64-ext and
:uint64-ext will need to be handled in gl/types.lisp

- Add function (glut::ensure-init) which is only used when saving a core. It ensures *argcp* and *argv* are
(cffi:null-pointer) in the core
- Make (glut:init) run initialization of base-window class rather than on load. Without this users of this
library would need to include a manual call to (glut:init) before running their own toplevel function.

Remove :no-error enum, which clashes with :zero, fixing check-error.

- Pull type checks outside the copy loop in with-opengl-array for some
  common element types, so cffi can optimize the conversions, array access,
  etc.
  Speeds up tex-image-2d of a 1024x1024 RGBA unsigned byte texture ~100x
  (from ~23sec w/~3.5GB consed, to ~0.25sec w/0 consed) on SBCL 1.0.2

  Handles all the types currently returned by symbolic-type->real-type,
  so should be good enough for tex-image-*. May need more types if
  with-opengl-array is used elsewhere, but falls through to the old
  code in that case, so should still work.

- fixes lispification of a bunch of the new function names.
- more type info for array of pointer args (:pointer (:pointer type))
  instead of (:pointer :pointer).
