virtual provides for local servers

[Patrice Dumas <pertusus free fr>]

Hello,

ltsp5 requires an xdmcp server, but more than one package provides the
functionnality. What about adding a virtual provides for local servers
like

Provides: server(xdmcp) 

This could also be used for smtpdaemon and webserver, which would become
server(smtp) and server(web) (or server(http))?

What do you think about that idea?
