JOGL GL4 preperation (cont):

- All available OpenGL versions (native/platform) are verified at GLProfile
  initialization and can be queried ..
  A mapping of major,compat -> major,minor,options is created.

- Removal of temp context creation, when creating a context.
  This was necessary to query general availability of ARB_create_context.
  Due to the shared context of X11GLXDrawableFactory and WindowsWGLDrawableFactory,
  this is no more necessary.
  Due to the version mapping, the ARB_create_context paramters are known.

- NativeWindow X11Lib: Added X11ErrorHandler, throwing a RuntimeException.
  Necessary to catch BadMatch .. etc X11 errors, eg for glXCreateContextAttribsARB
  Hence all X11 calls are covered now.

- X11DummyGLXDrawable needs to use an own Window, otherwise GLn n>2 fails

- Flattening the desktop GL* implementation,
  all use GL4bcImpl, which reduces the footprint dramatically.

- GL*Impl.isGL*() (desktop) utilizes the GLContext.isGL*(),
  hence the results reflect the actual native context version.

- GLContextImpl makeCurrent/create: Added workflow documentation,
  clarified code, defined abstract methods to have a protocol.

- Removed moved files (from here to gluegen),
  see gluegen a01cb3d59715a41153380f1977ec75263b762dc6

- NativeLibLoader -> <TYPE>JNILibLoader

- Fixed Exception Handling (as in gluegen bce53b52c8638729750c4286dbc04cb14329fd34),
  ie removed empty catch Throwable ..

- GLContext.setSwapInterval(): Nop in offscreen case, otherwise X11IOError (NVIDIA Bug)

Test:
  Tests
    - Junit
    - demos.gears.Gears
    - demos.jrefract.JRefract

  Platforms
    - Linux 64/32 ATI/NVidia
    - MacOsX
    - Windows (virtualbox 3.1.6, offscreen failed)

TODO/BUGS:
    - FIXME ATI GLn n>2 with AWT, can't make context current, works well on NVIDIA though
    - FIXME GL3GL4: Due to GL3 and GL4 implementation bugs, we still choose GL2 first, if available!
    - Add GL 3.3 to GL3/gl3ext.h
    - Add GL 4.0 to GL3/gl3ext.h and fix the GL3/GL4 seperation
    - Rename jogl.gl2.jar -> jogl.gldesktop.jar (as done with it's native lib already)
