Removed all known GLEW workarounds, added one small workaround for missing ARB_texture_compression_bptc. I didn't want to patch glLoadGen for just four enum values, this way it's possible to use stock one without any patching (except for missing OpenGL 2.1 support, as stated in external/OpenGL/GL/README.md). As one file now replaces both `glew.h` and `glcorearb.h` and it has the same size as `glcorearb.h` alone , it saves approximately 18k LOC, resulting in 15 second shorter compilation time (5:03 before, 4:48 now). Not bad.pull/23/head
