* 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.
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.
