1d85e405e6 Make the distinction between truly deterministic functions and date/time 
functions which only return the same answer for a single query.  Only truly
deterministic functions are allowed in indexes.  Add new expression index

1f9ca2c84c Add code to maintain indexes with expression arguments across DELETE, INSERT, 
and UPDATE statements.  Legacy tests pass, but the new code paths are still
largely untested.  The query planner currently makes no effort to use
expression indexes.

108aa00a87 Enhances the parser so that it accepts arbitrary expressions for the arguments 
of an index, though the code generator still rejects everything other than
simple column names.  The sqlite3RestrictColumnListSyntax() routine is removed
since that feature is now handled by the parser.

7cea7f95c7 Using "SELECT ALL" instead of just "SELECT" on a query that uses a single 
unflattenable subquery or view in its FROM clause will force the subquery to
be manifested into a temporary table rather than run incrementally using a
co-routine.  This is a stop-gap means of controlling the decision to manifest
while we try to work out a better to make that decision automatically.
