freeglut: Update to 3.4.0

pkgsrc changes:
---------------
  * Remove patches which have been merged upstream.
  * Apply recommandations of pkglint for tests on PKG_BUILD_OPTIONS.

upstream changes:
-----------------
* Add GLUT_ACTIVE_SUPER modifier, and corresponding GLUT_KEY_SUPER_L
and GLUT_KEY_SUPER_R special keys. These map to Windows/Command keys.
* Fix RGB mode (GLUT_RGBA) colors on 8bpp displays on windows
  (construct default RGB332 palette).
* Fix indexed color context creation on X11 and windows (GLUT_INDEX).
* Add missing colormap management functions for X11 and windows
  (glutSetColor, glutGetColor).
* Fix crash when calling glutTimerFuncUcall.
* Fix FreeBSD build by essentially disabling the joystick code for
  newer FreeBSD versions. It will eventually need to be replaced/fixed.
* Add fallbacks for the old GLX (<1.3) context creation API
(glXChooseVisual/glXCreateContext), makes us compatible with IRIX 5.x and
    other old UNIX systems.
* Add fallbacks for OpenGL 1.0 (no vertex arrays/client state).
* Use nanosleep instead of usleep on UNIX, which is more widely
  supported on old UNIX systems.
* Fix build on X11 if GL_SAMPLES is not defined.
* Fix overly strict context version checking on Android leading to
  context creation failure in some cases.
* Fix GLUT_CURSOR_INFO on windows, should be IDC_HAND, not IDC_HELP.
* Fix mismatched font declarations on X11.
* Add alternative simple ways to build freeglut with native tools only,
  without having to use cmake.
* Fix build on windows with cmake 3.0.0. Explicitly link with gdi32.
* Fix build on MSVC 2005.
* Fix build on MacOS X. Link with all the necessary X libraries.
* Fix build on SGI IRIX.
* Fix build on Android (mismatched function prototypes and missing
  glutCreateMenuUcall).
* Add support for the ninja multi-config generator.
* Removed spurious dependency on a C++ compiler. One of the demos was
  being compiled as C++ for no reason.
* Silence unnecessary warnings when VBOs or GLSL are not available.
* New demo programs: 3dview, keyboard, joystick.
* Documentation: added MacOS X build instructions.
* Made it possible to eventually support building freeglut as a single
  compilation unit, by avoiding name conflicts on static variables.
* Other minor fixes.
