[Qemu-devel] [RfC PATCH 07/11] spice: tls support

[Gerd Hoffmann <kraxel@redhat.com>]

Add options to the -spice command line switch to setup tls:

tls-port
	listening port

x509-dir
	x509 file directory.  Expects same filenames as
	-vnc $display,x509=$dir

x509-key-file
x509-key-password
x509-cert-file
x509-cacert-file
x509-dh-key-file
	x509 files can also be set individually.

tls-ciphers
	which ciphers to use.
