v2writable: reduce barriers

Since we handle the overview info synchronously, we only need
barriers in tests, now.  We will use asynchronous checkpoints
to sync less-important Xapian data.

For data deduplication, this requires us to hoist out the
cat-blob support in ::Import for reading uncommitted data
in git.
