I was fedup with having to run my tests as root and not being able to
use my usual setup for tests that only exercise the GT part of the GPU.
Render nodes to the rescue!

The goal is here to both: demonstrate a simple usage of render copy with
the possibility to write pngs to visualize what it's doing and to
provide a test bed to port the render copy function to new
architectures.

Use the display CRC support to validate cursor plane functionality.
The test will position the cursor plane either fully onscreen,
partially onscreen, or fully offscreen, using either a fully opaque
or fully transparent surface. In each case it then reads the PF CRC
and compares it with the CRC value obtained when the cursor plane
was disabled.
v2: Loop over all connectors and crtcs
Use igt_wait_for_vblank
Test more corner cases
Add some progress indication ala. kms_flip
Make it work for pf and pipe sources

We still need to dump some of the known sections explicitly due to
dependencies on information extracted, such as LFP data pointers and
panel_type.

At least on my old atom i945 they take forever. Also, metric tons of
pipe B underruns while running rcs-flip-vs-panning. No idea why that
happens.

Otherwise on machines where the only output available is restricted to
one pipe we'll have tons of "warn" results for no gain in the piglit
runner. All tests that use the kmstest helpers already check the
return value and do something sensible (like skip the tests if there's
really no config available).

We run flips and vblank waits in parallel, which means the step
for each is the maximum. If we'd switch to an interleaved scheme
(to be able to check the correlation) we'd need to add them instead.

We don't have a reference value for the vblank counter yet, so
will end up waiting for a long time for the vblank counter to
wrap around again.

It's broken since it doesn't take the order the events arrived into
account and so will fall over for longer seq_step values in the vblank
event: Since the flip completes right away, but the vblank later on
they won't have the same timestamp.
For now just give up, we could resurrect this by strictly alternating
between a flip and a vblank wait.

If the test gets stopped sometimes a helper process falls over.

Let's add a new test that sets a mode, wait for a few vblanks (3) and
then make sure we read 3 identical CRCs.
Some subtests check for various parsing errors.
In the process, improve the debugfs helpers to deal with CRCs.
