47d12f79de fixed the way of iterating over the range of map. 
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.

79574eea31 Port number 49153(BeginPortRange) would be returned twice, causing duplication and potential errors. 
If we first request port 49153 (BeginPortRange) explicitly, and later some time request the next free port (of same ip/proto) by calling RequestPort() with port number 0, we will again get 49153 returned, even if it's currently in use. Because findPort() blindly retured BeginPortRange the first run, without checking if it has already been taken.
