logind: extract has_vts() from can_multi_session()
We currently use seat_can_multi_session() to test for two things: * whether the seat can handle session-switching * whether the seat has VTs As both are currently logically equivalent, we didn't care. However, we want to allow session-switching on seats without VTs, so split this helper into: * seat_can_multi_session(): whether session-switching is supported * seat_has_vts(): whether the seat has VTs Note that only one seat on a system can have VTs. There is only one set of them. We automatically assign them to seat0 as usual. With this patch in place, we can easily add new session-switching/tracking methods without breaking any VT code as it is now protected by has_vts(), no longer by can_multi_session().
