8b57642259 Fix a bug in error reporting when a UNIQUE index on expressions fails its 
uniqueness test.

03bf26d90d Not only date/time functions, but also functions like sqlite_version() and 
changes() need to be prohibited from use inside of indexes.

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.
