Add Database::queryMulti(), which will execute an array of queries as a batch with minimal roundtrips. SQLite fallbacks to looping through each statement and invoking doQuery(). Add QueryStatus class to reduce complexity in Database. Rewrite doQuery() as doSingleStatementQuery(). Change-Id: I3d51083e36ab06fcc1d94558e51b38e106f71bb9
