Move pat backend to fully rbtree based implementation from the existing rbtree and linked list hybrid. New rbtree based solution uses interval trees (augmented rbtrees) in order to store the PAT ranges. The new code seprates out the pat backend to pat_rbtree.c file, making is cleaner. The change also makes the PAT lookup, reserve and free operations more optimal, as we don't have to traverse linear linked list of few tens of entries in normal case.
