This patch adds more Direct Rendering Manager ioctls to support
userland OpenGL and Vulkan drivers, in addition to existing
DRM_IOCTL_VERSION.
More device-specific ioctls are needed though, but they share the same
range from 0x40 to 0x9f. Adding these would break the current
DRM_IOCTL_I915_GETPARAM. I'm unsure about whether a generic
implementation is possible.
