For SQLite 3.14.0 and newer, we're using the v2 trace API. This means that the trace callback receives a pointer to the sqlite3_stmt object. We can use the sqlite3_stmt pointer to retrieve expanded SQL string.

The following statement...:
cur.executemany("insert into t values(?)", ((v,) for v in range(3)))

...will produce the following traces:
  insert into t values(0)
  insert into t values(1)
  insert into t values(2)

...instead of:
  insert into t values(?)
  insert into t values(?)
  insert into t values(?)
