why is this interface in public? i can't tell what will be used outside content
in the future.

(btw if you haven't seen it already,
https://www.chromium.org/developers/content-module/content-api is a good summary
of what goes in content/public)

Doh. This is public because the first iteration of this patch had the embedder
providing an implementation. It is totally unnecessary now, so fixed.

+ public:
+  MojoShellContext() {}
+  virtual ~MojoShellContext() {}
+
+  static scoped_ptr<MojoShellContext> Create();
+
+  static void SetApplicationRegistryInitializerForTesting(
+      const base::Callback<void(ApplicationRegistry*)>& callback);
+
+ private:
+  DISALLOW_COPY_AND_ASSIGN(MojoShellContext);
+};
+
+}  // namespace content
+
+#endif  // CONTENT_PUBLIC_BROWSER_MOJO_SHELL_CONTEXT_H_
