This fix prevents Libuv.pipe_connect from throwing when the stack
memory that was previously incorrectly interpreted as the int return
value happens to be negative.
When pipe_connect threw, an assertion failure would follow since the
pipe handle would be closed prematurely.

- Swallowing too many exceptions can end up hiding issues in
Kestrel itself. It's better to let the process die.
- If we want to handle certain exceptions we should be as
specific as possible with our try/catch blocks.
This change fixes the in-process marshalling of TCP handles on Mac and Linux
that is used to support having multiple threads accepting connections from
multiple loops.
On these two platforms, the ReadStart callback somtimes gets called with a
status and pipe_pending_count equal to zero. Now when the status is zero
just exit the callback without closing the pipe.
This change more closely follows the example at

- Previously an incomplete chunked response would be written instead.
- Add test to verify Content-Length: 0 is set automatically.
- Add test to verify HTTP/1.0 keep-alive isn't used if no Content-Length
is set for the response.
- Add tests to verify errors are handled properly after chunked writes.

The common use-case for Kestrel in production will be behind a reverse proxy such as Nginx. In cases where the reverse proxy is located on the same machine as the application, connecting via a UNIX socket is more efficient than a TCP socket, as it avoids going through the network layer. Accessing 127.0.0.1 through TCP still needs to initiate a TCP connection and perform handshaking, checksumming, etc, all of which is avoided by using UNIX sockets.
- Moved TCP-specific stuff from Listener into new TcpListener class (same with ListenerPrimary and ListenerSecondary)
- Made Listener abstract
- Created new PipeListener. Note that while the use case is for UNIX sockets, this is called "Pipe" in uv, so I've called this "PipeListener" so the terminology is consistant
- Uses "unix" URL scheme to determine whether to use socket. "http://127.0.0.1:5000" is for listening via TCP while "unix:///var/run/kestrel-test.sock" is for listening via UNIX socket
