Log message:
in an UpdateSet, match new files with old files based on their sha256.
avoid extracting again identical files, leading to less file system churn.
put in a few failsafes (size check) for people with fubar'd file
systems (hey oga@).
The more often you update, the more you gain. Over 6 months, about one
out of five files doesn't change.
apparently, improves things a lot on slow fs, as said landry@ and sthen@.
tested by quite a few people.
