Comment (by ryan):

 * Register blog-id-cache group as global
 * Introduce clean_blog_cache() so we can run it independently of
 refresh_blog_details() which assumes the blog still exists and
 get_blog_details() can be called.
 * Don't db escape cache keys
 * Return 0 for all failures in get_blog_id_from_url()
 * clean_blog_cache() after dropping tables in wpmu_delete_blog() to make
 sure the cache is for real cleaned.
