This is prep work for the btree key cache: btree iterators will point to

Hit an assertion, probably spurious, indicating an iterator was unlocked
when it shouldn't have been (spurious because it wasn't locked at all
when the caller called btree_insert_at()).
Add a flag, BTREE_ITER_NOUNLOCK, and tighten up the assertions
