7c9467d7a7 fix window function partition boundary search 
It was horribly broken and many test references were wrong. I'm
surprised I never noticed this.

4eb053a303 Implementaion of window function nth_value. 
1. Implemented the window function nth_value
2. Make the return type of lag/lead, and nth_value functions to be
ColumnNullable, thus the returned value can be null if it is out
of frame.
