New "default" buffer manager that aims to replace the current one, but

Added partial implementation of range tracking for pinning arbitrary

regions. Currently, tracks regions, and is O(m log(n)) for each
operation, where m is the number of transition points per range, and n
is the number of transition points in the system. A transition point is
a place in memory where the pincount changes.
