plagman 93b4d6182e Polymer: preliminary support for GL_ARB_debug_output
This won't actually do anything until the a debug bit is added when
creating the context, but that requires support for GLX_create_context
which SDL doesn't support. I'll add support for WGL_create_context to
winlayer in a bit as a stopgap.

Also updates our local copy of glext.h with a fresh one from the
Khronos registry.
