This series goes on top of Simon's excellent work to get
a TCP_INFO-based check_client_connection working under Linux.

First off, add a test extracted from one of Simon's messages;
then revert the signature changes to existing methods to
avoid breaking tmm1/gctools, and finally add a more portable
fallback for Ruby 2.2+ users (tested on FreeBSD).

Further work will improve portability of raindrops for FreeBSD
(and maybe other *BSDs incidentally, too).  That will be sent to
raindrops-public@bogomips => https://bogomips.org/raindrops-public/

This was a bit tricky to test, but it's probably more reliable
now that we're relying on TCP_INFO.

Based on test by Simon Eskildsen <simon.eskildsen@shopify.com>:

We can force kgio_tryaccept to return an internal class
for TCP objects by subclassing Kgio::TCPServer.

This avoids breakage in any unfortunate projects which depend on
our undocumented internal APIs, such as gctools
<https://github.com/tmm1/gctools>

Ruby 2.2+ can show "struct tcp_info" as a string via
Socket::Option#inspect, and we can attempt to parse it
out to extract the information we need.

Parsing this string is inefficient, but does not depend on the
