nit: const for headers?

also, I think non-virtuals should be listed before the virtuals above.

Changed to const.

There is no explicit style guide on placing non-virtuals vs. virtuals. But as
AwBrowserContext puts non-virtuals first, made the same here for consistency.

+  std::string GetExtraHeaders(const GURL& url);
+
+ private:
+  net::URLRequestContextGetter* getter_;
+  base::Lock lock_;

nit: it'd be nice to say what this is protecting..

Renamed to extra_headers_lock_.
