33e619fc1c Additional refinements to Expr handling. Restore compression of trigger 
expressions.  Change Expr.zToken to Expr.u.zToken and added Expr.u.iValue.
Remove an unnecessary ExprDup from CHECK constraint processing.  And so forth. (CVS 6682)

removing the Token.dyn and Token.quoted fields. (CVS 6681)

c4a64facce Rework the logic that generates a schema for tables created using 
"CREATE TABLE ... AS SELECT ...".  Instead of trying to copy the raw
datatype string from the right-hand side, just make the type one 
of TEXT, INT, REAL, NUM, or nothing.  This is much simpler than 
trying to parse and quote datatype strings.  Other minor 
implifications to build.c are bundled with this change. (CVS 6626)

8a1e594c9f Simplifications to the symbol table implementation in hash.c. For very small 
symbol tables (less than 10 entries) a simple linked list is used instead
of a hash table.  Number of hash table buckets is limited to prevent large
allocations. (CVS 6559)

limitation, uses less memory, and gives better bounds on worst-case
performance.  The Rowhash implementation has yet to be removed. (CVS 6534)
