Can't run the test if the required Xapian tools are missing.

I've noticed performance problems in Xapian's old chert
backend which seem alleviated with the new glass backend;
particularly related to phrase searches.
Unfortunately, the tool distributed with Xapian for updating DB
formats, copydatabase(1), is extremely slow and blocking updates
for hours at a time to perform the migration is not acceptable.
(That's right, "copydatabase" is NOT a Postgres command!)
So, I've written "public-inbox-xcpdb" and gotten it to perform
the bulk copy operation without holding inbox.lock and have it
deal gracefully with Xapian DB modifications. xcpdb is still
slow, but I've (finally!) implemented partial reindexing to
allow it to minimize the lock time and not stall -mda or -watch
processes while it is working.
There's a bunch of cleanups along the way, too; and it should
make future changes to repartition the Xapian DB on existing v2
inboxes easier.
