[Jamey Sharp]

- Don't warn for references to deprecated functions in xorg_symbols.
- Ignore functions generated by gl_apitemp.py that are never used.

Sorry I didn't reply, Guillem. It seems better to me to keep the definition
local rather than requiring new API from the x11proto module, particularly
since I don't want to encourage people to suppress the "possibly unused"
warnings without thinking carefully about them, so I'm resubmitting this patch
unchanged.
