Title: tcp: getsockname() returns its address family name

``TCP.getsockname()`` return an object of which property has an integer of its address family as
``{ port: 12345, family: 2, address: '127.0.0.1' }``
and its description in the doc was missing. This patch changes its value to a string as
`` { port: 12345, family: 'AF_INET', address: '127.0.0.1' }``
for easy to be recognized. And it also adds the doc.
