Change the RETURNING algorithm so that outputs accumulate in an ephemeral
table until all modifications have been completed, and only then do results
start being returned. This should help prevent problems with interleaved
sqlite3_step() calls on two separate DML statements. It also seems to be
closer to how PostgreSQL works, which might prevent compatibility problems.
