6f32848d61 Move the definitions of the WhereLevel and WhereInfo objects out of
sqliteInt.h and into where.c.  This will facilitate future refactoring
of the internal query planner data structures.

2722898c6c Make sure the authorizer callback gets a valid pointer to "ROWID" for the
column-name parameter when doing an UPDATE that changes the rowid.
Fix for ticket [0eb70d77cb05bb2272].

b07028f71c Add assert() statements and eliminate needless variable assignments in order
to get the clang scan-build utility to report zero problems against the
SQLite core.  Clang's static analysis did find one real problem - but it was
in the command-line shell, not in the SQLite core.

7006c18e00 When updating a field that requires foreign key constraints be checked, ensure that the indexes and tables are consistent when the FK logic is run. Otherwise, it may detect the inconsistency and report database corruption.

d4187c716c Provide hints to the btree layer during the creation of transient tables
when it is possible for those tables to use a hash rather than a binary tree.
No use is current made of those hints, though assert() statement verify
their accuracy.

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.).
