attachment urls

 The current backfill_attachment_urls() approach causes a REPLACE query for
 each attachment url. This can cause the invalidation of a lot of data and
 also cause MySQL replication lag in some cases.

 The attached patch will make sure to bundle these requests and perform
 only maximum of one db update per post.
