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.
