He Jie Xu 183c3d5f07 Remove extensions module
The most of objects are removed from the extensions module. The last
thing is the expected_errors decorator, but that decorator is nothing
about the extensions. So move the decorator to the wsgi module where
is the place put the other decorator also. Then we can remove the
extensions module entirely.
