If option '--key' is not specified. 'WebSockifyServer class' will
inital self.key as empty string. but ssl load_cert_chain function
will raise error 'no such file' with keyfile param empty string.
* Incorporates #190 without breaking compatibility towards old Python versions.
* A new plugin allows authenticating clients by the "common name" defined in their certificate.
* Added manual for certificate-based client authentication, including hints to which Python versions allow client certificate authentication.
* Adjusted test to work with new ssl.create_default_context.
Fixes a problem that occurs in Chrome 61 where the following error message appears in the console:
'Failed to load module script: The server responded with a non-JavaScript MIME type of "".
Strict MIME type checking is enforced for module scripts per HTML spec.'
In python 2 the ssl.wrap_socket doesn't work on sockets created using socket.fromfd.
The workaround is to wrap the socket returned by socket.fromfd into another socket
object using the private _sock constructor parameter.
With the --inetd parameter, websockify doesn't require the source_addr and
source_port paramters and it expects that stdin is already opened and listening
socket.
This way websockify can be used with (x)inetd or as a systemd socket-activated
service.
This only enables the SIGCHLD handler if SIGCHLD
exists, such that platforms without SIGCHLD (such
as windows) can still run websockify natively.
See #108
The socket.sendall method is called indirectly via calls
to the python3.6 BaseHTTPRequestHandler.send_error method
which is called by both the Web*RequestHandler classes as
shown below:

The WebSocket standard require us to choose one of the protocols
supported by the client. Enforce this with a specific check in the
base class rather than relying on generous clients.
The native WebSocket is in a much better position to do queue
management than us. Many callers also failed to notice this part
of the API, causing stalls.
Sync with noVNC as of commit ae510306b5094b55aa08a2a0d15a151704f70993.
The main change is to make it a more proper object that you can
instantiate multiple times.
Otherwise we might misinterpret trailing binary data as a second
HTTP request. This happens when we return from the handler with
data still queued up in the socket.
The TCP_KEEPCNT option for sockets only work with the Linux kernel,
this isn't available for example in FreeBSD and Hurd, which makes the
package fail to build on these platforms. See Debian bug here:
https://bugs.debian.org/840035
mox is pretty much unmaintained these days, however the OpenStack
project are actively maintaining mox3 (a Python 3 compatibile fork
with some other improvements).
websockify seems quite happy to use mox3 instead, so switch the
test dependency and associated imports to use mox3.
