[Spice-devel] [qxl 4/5] build: Error out when enabling xspice with X.Org 1.19

[Christophe Fergeau]

xspice needs to be updated to cope with some X.Org 1.19 API changes,
better to make that explicit at configure time rather than letting
people discover the hard way (it builds with warnings but will not work)
that it's broken.
