[Spice-devel] [xf86-video-qxl v5] Enable smartcard support for XSpice.

This is done by creating a Unix domain socket to which smartcard
messages are transferred, using the vscard protocol.
A further system library, spiceccid, is used to provide an interface into
pcsc-lite, specifically the pcsc-lite daemon, so that regular Unix applications
can access the passed through smartcard information.
