Keith Packard e4e3447603 Add RandR leases with modesetting driver support [v6] 
This adds support for RandR CRTC/Output leases through the modesetting
driver, creating a lease using new kernel infrastructure and returning
that to a client through an fd which will have access to only those
resources.

v2:	Restore CRTC mode when leases terminate

	When a lease terminates for a crtc we have saved data for, go
	ahead and restore the saved mode.

v3:	Report RR_Rotate_0 rotations for leased crtcs.

	Ignore leased CRTCs when selecting screen size.

	Stop leasing encoders, the kernel doesn't do that anymore.

	Turn off crtc->enabled while leased so that modesetting
	ignores them.

	Check lease status before calling any driver mode functions

	When starting a lease, mark leased CRTCs as disabled and hide
	their cursors. Also, check to see if there are other
	non-leased CRTCs which are driving leased Outputs and mark
	them as disabled as well. Sometimes an application will lease
	an idle crtc instead of the one already associated with the
	leased output.

	When terminating a lease, reset any CRTCs which are driving
	outputs that are no longer leased so that they start working
	again.

	This required splitting the DIX level lease termination code
	into two pieces, one to remove the lease from the system
	(RRLeaseTerminated) and a new function that frees the lease
	data structure (RRLeaseFree).

v4:	Report RR_Rotate_0 rotation for leased crtcs.

v5: Terminate all leases on server reset.

	Leases hang around after the associated client exits so that
	the client doesn't need to occupy an X server client slot and
	consume a file descriptor once it has gotten the output
	resources necessary.

	Any leases still hanging around when the X server resets or
	shuts down need to be cleaned up by calling the kernel to
	terminate the lease and freeing any DIX structures.

	Note that we cannot simply use the existing
	drmmode_terminate_lease function on each lease as that wants
	to also reset the video mode, and during server shut down that

   modesetting: Validate leases on VT enter

	The kernel doesn't allow any master ioctls to run when another
	VT is active, including simple things like listing the active
	leases. To deal with that, we check the list of leases
	whenever the X server VT is activated.

   xfree86: hide disabled cursors when resetting after lease termination

	The lessee may well have played with cursors and left one
	active on our screen. Just tell the kernel to turn it off.

v6:	Add meson build infrastructure

[Also bumped libdrm requirement - ajax]
