1b26c7ccfa Remove the rowhash object from the code. Rowset now fills its role. (CVS 6535)

733bf1b1e2 Extend the Rowset object to contain all the capabilities of Rowhash in 
addition to its legacy capabilities.  Use Rowset to replace Rowhash.
In addition to requiring less code, This removes the 2^32 result row
limitation, uses less memory, and gives better bounds on worst-case
performance.  The Rowhash implementation has yet to be removed. (CVS 6534)
