Typically UNIX domain sockets are created with more liberal
file permissions than the rest of the application. By default,
we create UNIX domain sockets to be readable and writable by
all local users to give them the same accessibility as
locally-bound TCP listeners.
This only has an effect on UNIX domain sockets.
This was inspired by Suraj Kurapati in

This ensures any string literals that pop up in *our* code will
just be a bag of bytes. This shouldn't affect/fix/break
existing apps in most cases, but most constants will always have
the "correct" encoding (none!) to be consistent with HTTP/socket
expectations. Since this comment affects things only on a
per-source basis, it won't affect existing apps with the
exception of strings we pass to the Rack application.
This will eventually allow us to get rid of that Unicorn::Z
constant, too.

Otherwise the GC will unlink sockets. A better
solution (purgatory?) may be needed...

This removes the #unicorn_peeraddr methods from TCPSocket and
UNIXSocket core classes. Instead, just move that logic into the
only place it needs to be used in HttpRequest.

Apparently I was smoking crack and thought they weren't
changeable. Additionally, SO_REUSEADDR is set by TCPServer.new,
so there's no need to set it ourselves; so avoid putting
extra items in the purgatory.
This allows SIGHUP to change listen options.

I can't think of a good reason to ever use restrictive
permissions with UNIX domain sockets for an HTTP server.
Since some folks run their nginx on port 80 and then
have it drop permissions, we need to ensure our socket
is readable and writable across the board.
The reason I'm respecting the existing umask at all (instead of
using 0000 across the board like most daemonizers) is because
the admin may want to restrict access (especially write access)
to log files.

bind_listen takes a hash as its second parameter now, allowing
the addition of :sndbuf and :rcvbuf options to specify the size
of the buffers in bytes. These correspond to the SO_SNDBUF and
SO_RCVBUF options via setsockopt(2) respectively.
This also adds support for per-listener backlogs to be used.
However, this is only an internal API change and the changes
have not yet been exposed to the user via Unicorn::Configurator,
yet.
Also add a bunch of SocketHelper tests
