Implements VK_KHR_display, VK_EXT_direct_mode_display and
VK_EXT_acquire_xlib_display using DRM/KMS.
This uses X leases to provide the same API as nVidia, allowing an
application to discover available display resources and acquire one
from the X server using RandR leases.
Because Linux DRM does not allow access to KMS resources through a
render node, applications must use vkGetRandROutputDisplayEXT to
access a suitable VkDisplayKHR object as
vkGetPhysicalDeviceDisplayPropertiesKHR will not be able to see the
required kernel objects.
Contrarywise, nVidia masks off some RandR outputs from X (such as
head-mounted-displays), those are *only* visible through
vkGetPhysicalDeviceDisplayPropertiesKHR. Hence, an application wanting
to work with both systems may need to use both mechanisms to locate
the desired output device.
v2:
Rework VK_KEITHP_kms_display extension to just use a data
structure.
v3:
Restructure to provide KMS access using the existing
VK_EXT_acquire_xlib_display instead of creating a new
extension.
Rebase on more recent mesa master
