Why did you separate the ARB version from the EXT version?

The bindings should fallback to the right implementation depending on the
extensions availability. I.e. if you specify:
 'names': ['glDeleteQueriesARB', 'glDeleteQueriesEXT']

Then you can call glDeleteQueriesARB in chromium code, and that will call
glDeleteQueriesEXT in the driver if that's what's available.

That avoids a large number of unnecessary if tests in chromium code, since both
calls are meant to be equivalent.

Does that mean I should be calling glDeleteQueriesARB() when I intend to call
glDeleteQueriesEXT()? or should there be a separate entry just for
glDeleteQueriesEXT() as well?
