Make the debugging line numbers in the amalgamation more accurate. (check-in: 3b34e95ca8 user: mistachkin tags: trunk)

Use a WITHOUT ROWID table to index fts5 btree leaves. This is faster to query and only slightly larger than storing btree nodes within an intkey table. (check-in: 862418e350 user: dan tags: fts5-btree-index)
