  1. replace simple IP pool free table with LRU implementation 

    The free table was effectively acting as a queue (LRU). push and
pop operation where fast, but a direct removal of a single item
did require a full table scan.
For large IP pools, that could lead to unacceptable delays.

The LRU implementation uses two indexes and is much faster when
removing an item from the middle of the queue.
