Exposed to the extras as extrasExports (on the builtins object), on which they can put things that should be accessible from C++. Exposed to C++ through the V8 API as v8::Context::GetExtrasExportsObject(). Adding a test (in test-api.cc) required adding a simple extra, test-extra.js, which we build into the standalone builds.
