[PATCH xserver 0/4] Add RandR 1.6 lease support

[Keith Packard]

This is an updated version of this series, rebased on current master
and including v3 of the main patch. That final patch has a description
of the changes from v2, but the main thing is a lot of changes needed
to keep the server from doing anything with the leased objects or
including them in any computations. The only real change in the design
is that the server now restores modes when leases terminate.

This requires randrproto 1.6 and current drm-next kernel bits.

Thanks for your consideration and review,
