Changes since last version:
* Add local definitions of new ioctls to avoid dependency on proposed libdrm bits.
* Remove FIRST_PIXEL_OUT as that has been removed from the proposed kernel interface
* Add tests for get_lease and list_lessees
* Fix commit message on the lease test patch
These ioctls replace drmWaitVBlank and add ns time resolution and 64-bit sequence numbers to comply with the Vulkan API specifications.
The tests were derived from the existing kms_vblank tests with the 'wait' variant elided as the new API doesn't provide a mechanism for blocking in the kernel.
v2: from Dave Airlie airlied@redhat.com
* Add local definitions of new ioctls to avoid requiring latest libdrm.
* Remove FIRST_PIXEL_OUT as that has been removed from the proposed kernel patches.
