Use glad instead of GLEW.

glad is a more modern, cleaner, and flexible alternative to GLEW.  In
particular it has first-class citizen support for OpenGL ES end EGL.

Glad can't be used just for defines.  For old demos which only need
defines, we could bundle Khronos glext, but for now place the necessary
defines on gl_wrap.h
