Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to
linux 4.19.34.

Adds support for more Intel hardware:
Broxton/Apollo Lake (was is_preliminary in 4.4)
Amber Lake (another Kaby Lake refresh)
Gemini Lake
Coffee Lake
Whiskey Lake
Cannon Lake (though no hardware with Intel graphics ever shipped)
Ice Lake (alpha support, hardware not released)

This does not add support for new radeon hardware on the AMD side as
newer radeons have a different kernel driver (amdgpu).

Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for
helping and a bunch of other developers for testing.

Update inteldrm(4) to code based on Linux 4.4.70. This brings us support for
Skylake and Cherryview and better support for Broadwell and Valleyview. Also
adds MST support. Some tweaks to the TTM code and radeondrm(4) to keep it
working with the updated generic DRM code needed for inteldrm(4).

Tested by many.

Update inteldrm to the code from Linux 3.14.52 (which corresponds to
commit 48f8f36a6c8018c2b36ea207aaf68ef5326c5075 on the linux-3.14.y
branch of the linux-stable tree). This brings preliminary support for
the GPU on Intel's Broadwell CPUs. Don't expect these to work
perfectly yet. There are some remaining issues with older hardware as
well, but no significant regressions have been uncovered.

This also updates some of drm core code. The radeondrm code remains
based on Linux 3.8 with some minimal canges to adjust to changes in
the core drm APIs.

Joint effort with jsg@, who did the initial update of the relevant drm
core bits. Committing this early to make sure it gets more testing
and make it possible for others to help getting the remaining wrinkles
straightened out.

Add a port of the TTM and Radeon DRM code from Linux 3.8.13.
Includes kernel modesetting, framebuffer console and support
for newer hardware.

Firmware needs to be present for acceleration and in some cases
modesetting to work. It can be installed via fw_update
or manually via pkg_add.

With lots of help from kettenis@ some macppc bits from mpi@
and some ttm refcount/queue bits from FreeBSD.

Significantly increase the wordlist for ddb hangman,
and update our device independent DRM code and the Intel DRM code
to be mostly in sync with Linux 3.8.3. Among other things this
brings support for kernel modesetting and enables use of

and with lots of help from kettenis@ (including a beautiful accelerated
wscons framebuffer console!)
