vnc: remove support for deprecated tls, x509, x509verify options
The 'tls-creds' option accepts the name of a TLS credentials object. This replaced the usage of 'tls', 'x509' and 'x509verify' options in 2.5.0. These deprecated options were grandfathered in when the deprecation policy was introduded in 2.10.0, so can now finally be removed. Signed-off-by: Daniel P. Berrangé <berrange@redhat.com> Message-id: 20180725092751.21767-3-berrange@redhat.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

Require that client use TLS when communicating with the VNC server. This

attack. It is recommended that this option be combined with either the

@option{x509} or @option{x509verify} options.

Valid if @option{tls} is specified. Require that x509 credentials are used

to provide authentication of the client when this is used. The path following

this option specifies where the x509 certificates are to be loaded from.
|

See the @ref{vnc_security} section for details on generating certificates.
|

This option is now deprecated in favour of using the @option{tls-creds}

Valid if @option{tls} is specified. Require that x509 credentials are used
|
||||
for negotiating the TLS session. The server will send its x509 certificate
|
||||
to the client, and request that the client send its own x509 certificate.
|
||||
The server will validate the client's certificate against the CA certificate,
|
||||
and reject clients when validation fails. If the certificate authority is
|
||||
trusted, this is a sufficient authentication mechanism. You may still wish
|
||||
to set a password on the VNC server as a second authentication layer. The
|

path following this option specifies where the x509 certificates are to
