Finished implementing all user-data callbacks (GCC-only for now).
Updated glutCreateMenu, glutIdleFunc, and glutTimerFunc so they handle NULL callback cases. Removed glutMenuStateFuncUcall (as glutMenuStateFunc is a depreciated function). git-svn-id: https://svn.code.sf.net/p/freeglut/code/trunk@1809 7f0cb862-5218-0410-a997-914c9d46530a
