Merge branch 'refs/heads/t/si_update'

A single patch which teaches the afs event handler to trigger a status
item update when the image or lyrics table changes. This patch had a
bug which was only noticed after the branch had been merged to next.
Therefore the series contains a fixup commit.

Cooking for almost two months.

* refs/heads/t/si_update:
  server: Avoid NULL pointer dereference in make_status_items().
  Update status items on blob events.
