aac39e1ded Merge trunk enhancements, and espeically the fix for allowing strings 
as column identifers in CREATE INDEX statements.

edb04ed946 Continue to support the (broken) legacy syntax of allowing strings for 
column names in CREATE INDEX statements and in UNIQUE and PRIMARY KEY
constraints.

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
test cases.

1f9ca2c84c Add code to maintain indexes with expression arguments across DELETE, INSERT,

largely untested.  The query planner currently makes no effort to use
expression indexes.
