Feature #5959: Addrinfo#inspectname

Target version:
Addrinfo の導入によって、Socket.getaddrinfo での正引き結果がオブジェクト化され、
元のホスト名を inspect で見れるようになってとても便利になったわけですが、
現在この元のホスト名をとりだす API がありません。
ホスト名とIP アドレスをセットで扱うのに、つまり解決済みの名前とアドレスの組を扱うのに Addrinfo って便利なので、
ホスト名を取り出す API が欲しいです。
現在の C での名前、inspectname か hostname あたりでどうでしょう。
