0af16ab2c2 Make sure that GROUP BY terms select input column names in preference to 
output column names, in compliance with the SQL standard.

e35463b312 Bare identifiers in ORDER BY clauses bind more tightly to output column name, 
but identifiers in expressions bind more tightly to input column names.
This is a compromise between SQL92 and SQL99 behavior and is what
PostgreSQL and MS-SQL do.  Ticket [f617ea3125e9c].

58a450c041 Treat identifiers in the HAVING clause the same as in the WHERE clause.

fixes a bug found by [http://www.sqlite.org/sqllogictest/ | SqlLogicTest]

1db95106ee Currently, if SQLite cannot find a table or index referred to by a query, it reloads the database schema from disk to see if the table or index has been added since the schema was cached in memory. Extend this behaviour to columns (which may have been added using ALTER TABLE) and fix some obscure cases related to tables and indexes (INDEXED BY, DROP TABLE etc.).
