Pull drm ci scripts from Dave Airlie:
"This is a bunch of ci integration for the freedesktop gitlab instance
where we currently do upstream userspace testing on diverse sets of
GPU hardware. From my perspective I think it's an experiment worth
going with and seeing how the benefits/noise playout keeping these
files useful.

Ideally I'd like to get this so we can do pre-merge testing on PRs
eventually.

Below is some info from danvet on why we've ended up making the
decision and how we can roll it back if we decide it was a bad plan.

Why in upstream?

- like documentation, testcases, tools CI integration is one of these
things where you can waste endless amounts of time if you
accidentally have a version that doesn't match your source code

- but also like the above, there's a balance, this is the initial cut
of what we think makes sense to keep in sync vs out-of-tree,
probably needs adjustment

- gitlab supports out-of-repo gitlab integration and that's what's
been used for the kernel in drm, but it results in per-driver
fragmentation and lots of duplicated effort. the simple act of
smashing an arbitrary winner into a topic branch already started
surfacing patches on dri-devel and sparking good cross driver team
discussions

Why gitlab?

- it's not any more shit than any of the other CI

- drm userspace uses it extensively for everything in userspace, we
have a lot of people and experience with this, including
integration of hw testing labs

- media userspace like gstreamer is also on gitlab.fd.o, and there's
discussion to extend this to the media subsystem in some fashion

Can this be shared?

- there's definitely a pile of code that could move to scripts/ if
other subsystem adopt ci integration in upstream kernel git. other
bits are more drm/gpu specific like the igt-gpu-tests/tools
integration

- docker images can be run locally or in other CI runners

Will we regret this?

- it's all in one directory, intentionally, for easy deletion

- probably 1-2 years in upstream to see whether this is worth it or a
Big Mistake. that's roughly what it took to _really_ roll out solid
CI in the bigger userspace projects we have on gitlab.fd.o like
mesa3d"

drm: Add initial ci/ subdirectory

Developers can easily execute several tests on different devices
by just pushing their branch to their fork in a repository hosted
on gitlab.freedesktop.org which has an infrastructure to run jobs
in several runners and farms with different devices.

There are also other automated tools that uprev dependencies,
monitor the infra, and so on that are already used by the Mesa
project, and we can reuse them too.

Also, store expectations about what the DRM drivers are supposed
to pass in the IGT test suite. By storing the test expectations
along with the code, we can make sure both stay in sync with each
other so we can know when a code change breaks those expectations.

Also, include a configuration file that points to the out-of-tree
CI scripts.

This will allow all contributors to drm to reuse the infrastructure
already in gitlab.freedesktop.org to test the driver on several
generations of the hardware.
