f78baafe41 Apply the same restrictions on constant refactoring to statements within a trigger program as top-level statements. Candidate fix for [ae3c5670b6].

6fea83e52c Ignore the database name on the target table when parsing a CREATE TABLE 
statement out of the sqlite_master table.  This is a fix for
ticket [d6ddba6706353] that preserves backwards compatibility.

5d9c9da6e8 Create and use a function especially for adding the ParseSchema opcode. 
This gives a small reduction in code and a small performance increase.

7687c83d4c Add an OP_VerifyCookie instruction to "CREATE XXX IF NOT EXISTS" commands. This way, if the specified database object existed when the statement was compiled but removed from the database before sqlite3_step() was called, the statement still works as expected (and creates the object).

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.).
