bookmarks: show outgoing bookmarks more exactly

Before this patch, "hg outgoing -B" shows only bookmarks added
locally. Then, users can't know about bookmarks below before "hg push"
execution.

  - deleted locally (even though it may be added remotely from "hg pull" view)
  - advanced locally
  - diverged
  - changed (= remote revision is unknown for local)

This patch shows such bookmarks, too.
