We need to ensure the portability of the sd_listen_fds emulation
test, too, which didn't get tested on my FreeBSD 10.3 install
due to it being on Ruby 2.2

* [ANN] unicorn 5.3.0 - Rack HTTP server for fast clients and Unix

unicorn is an HTTP server for Rack applications designed to only serve
fast clients on low-latency, high-bandwidth connections and take
advantage of features in Unix/Unix-like kernels.  Slow clients should
only be served by placing a reverse proxy capable of fully buffering
both the the request and response in between unicorn and slow clients.

Changes:

unicorn 5.3.0

A couple of portability fixes from Dylan Thacker-Smith and
Jeremy Evans since 5.3.0.pre1 over a week ago, but this looks
ready for a stable release, today.

When I started this over 8 years ago, I wondered if this would
just end up being an April Fools' joke.  Guess not.  I guess I
somehow tricked people into using a terribly marketed web server
that cannot talk directly to untrusted clients :x  Anyways,
unicorn won't be able to handle slow clients 8 years from now,
either, or 80 years from now.  And I vow never to learn to use
new-fangled things like epoll, kqueue, or threads :P

Anyways, this is a largish release with several new features,
and no backwards incompatibilities.

Simon Eskildsen contributed heavily using TCP_INFO under Linux
to implement the (now 5 year old) check_client_connection feature:

  https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-check_client_connection
  https://bogomips.org/unicorn-public/?q=s:check_client_connection&d:..20170401&x=t

This also led to FreeBSD and OpenBSD portability improvements in
one of our dependencies, raindrops:

   https://bogomips.org/raindrops-public/20170323024829.GA5190@dcvr/T/#u

Jeremy Evans contributed several new features.  First he
implemented after_worker_exit to aid debugging:

  https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-after_worker_exit
  https://bogomips.org/unicorn-public/?q=s:after_worker_exit&d:..20170401&x=t#t

And then security-related features to isolate workers.  Workers
may now chroot to drop access to the master filesystem, and the
new after_worker_ready configuration hook now exists to aid with
chroot support in workers:

  https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-after_worker_ready
  https://bogomips.org/unicorn/Unicorn/Worker.html#method-i-user
  https://bogomips.org/unicorn-public/?q=s:after_worker_ready&d:..20170401&x=t#t
  https://bogomips.org/unicorn-public/?q=s:chroot&d:..20170401&x=t#t

Additionally, workers may run in a completely different VM space
(nullifying preload_app and any CoW savings) with the new
worker_exec option:

  https://bogomips.org/unicorn/Unicorn/Configurator.html#method-i-worker_exec
  https://bogomips.org/unicorn-public/?q=s:worker_exec&d:..20170401&x=t#t

There are also several improvements to FreeBSD and OpenBSD
support with the addition of these features.
