This also includes a bunch of updates to the actual samples that have
become stale as things have changed in the tree and naughty developers
haven't updated the docs. This new bit of logic in the samples test
should help prevent that in the future.
In order to verify the static doc/api_samples files, this adds a new
method to the base test, which allows the subclasses to refine their
subs into pattern matches after the server response is verified, and
before the doc/api_samples file is verified.
