Fixed the following errors:
1. Request(0) causes a dead loop when the map is full and map.last == BEGIN.
2. When map.last is the only available port (or ip), Request(0) returns ErrAllPortsAllocated (or ErrNoAvailableIPs). Exception is when map.last == BEGIN.

Since it is possible to request a specific IP, IPAllocator has to verify
that the request is within boundaries.

We don't need ordered set anymore, also some cleanings and simple
benchmark.
