	IPv6 support for SocketCore class.
	TODO: In SocketCore::establishConnection(), this is insufficient 
to
	determin the failure of connect() here because the socket is
	non-blocking state. The next addresses should be tried after 
select().
	TODO: NameResolver still uses c-ares(<= 1.4) 
ares_gethostbyname().
	If c-ares 1.5 or newer is installed, ares_getaddrinfo() should 
be used
	instead which address family independent.
	TODO: DHTRoutingTable{Deserializer,Serializer} currently saves 
peer
	information in a compact peer format which is for IPv4 only.
	
	Some BitTorrent functions in PeerMessageUtil still depends on 
IPv4 but
	this is a spec of BitTorrent protocol.
	* src/SocketCore.{h, cc}
	* src/PeerMessageUtil.cc
	* test/SocketCoreTest.cc
	* test/PeerMessageUtilTest.cc
	* test/DHTConnectionImplTest.cc

	Handle IPv4-mapped addresses.
	* src/DHTNode.cc: Now identity is determined by node id.
	* src/DHTMessageTrackerEntry.cc

	Because now PeerMessageUtil::unpackcompact() could fail, the 
caller
	should handle it.
