Add OpenGL 3.x compatibility profile GL3bc,

where 'bc' is not a religious remark,
but simply means 'backward compatible' :)

GL3bc := GL2 + GL3,
hence the interface does not define any new values or methods.

Moved GL3's 3.1 part from gl3.h to gl3ext.h,
so it can be included in gl3bc.c, besides gl2.h.
