syncbase: syncQL: implement functions in select clause.

Functions were previously implemented but were only allowed
in expressions in the where clause.  This follow on change allows
functions in the select clause.

As such, select clause "selectors" may be fields or functions.
For example:
select v.CustNum, UpperCase(v.Name) from Customer where t= "Customer"

Note: This change renames ColumnEntry to "Selector" (requested by kash
in a post submit comment to a previous change).
