Subject: [sql] Ship Favicons recovery code to beta and stable.
The code has been running without event on dev and canary for many
weeks, the histograms have changed in a manner consistent with
databases no longer being corrupt. Everyone should share this.
Add some histograms to track the amount of data recovered.
