A largish release with several new features.

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

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

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

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:

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

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