	To make a listening socket non-block:
	
	* src/SocketCore.h
	(setNonBlockingMode): New function.
	* src/SocketCore.cc
	(setNonBlockingMode): New function.
	(beginListen): Added a call to setNonBlockingMode().
	(acceptConnection): Call setNonBlockingMode().
	(setBlockingMode): Updated.

	To handle tracker's NAT-checking:
	
	* src/PeerConnection.cc
	(receiveHandshake): 'msg' param is filled with received data and
	its length is assigned to 'length' param, even if all handshake
	message is not yet received.
	* src/PeerInteractionCommand.cc
	(executeInternal): Use peerInteraction->receiveHandshake(true) 
when
	a new peer connects to localhost.
	A call to peerInteraction->sendHandshake() was removed because 
	it is called from peerInteraction->receiveHandshake(true).
	* src/PeerInteraction.h
	(quickReplied): New variable.
	(receiveHandshake): Added an argument.
	* src/PeerInteraction.cc
	(PeerInteraction): Added the initialization of quickReplied.
	(receiveHandshake): Send handshake message as soon as the info 
hash
	in a handshake message from a peer is correct.

	
	To change the random part of peer id and key parameter:

	* src/TorrentMan.h
	(key): New variable.
	* src/TorrentMan.cc
	(setupInternal1): Use Util::randomAlpha() to generate random 
part
	of peer id, which is now "-aria2-"+13 alphabet 
characters([A-Za-z]).
	key is also generated by Util::randomAlpha() and it is now 8 
character
	long.
	* src/Util.h
	(randomAlpha): New function.
	* src/Util.cc
	(randomAlpha): New function.
	* src/TrackerWatcherCommand.cc
	(execute): In a tracker request: Use torrentMan->key as key 
parameter.
	Added no_peer_id=1.
	
	Set snubbing flag to false when a choke message is received from 
a
	snubbed peer.

	* src/ChokeMessage.cc
	(receivedAction): Set snubbing flag to false.
