After igt_display_commit() one can safely look at the CRC.

It'd be nice to have symbolic names for planes instead of using an index
in igt_output_get_plane().
We also namespace the enum to not conflict with anyone.

The goals here are:
- Reduce duplicated code in each KMS test
- Provide an API that looks more like what we want for atomic
modesets. The hope is then that it'll be easy to switch, at
run-time, between the "legacy" path and atomic modesets, keeping
the same API for tests.

We need to first check whether we'll even run the testcase before
deciding to print a premature SKIP/FAIL. Without this and global
skipped resulted in superflous output when running only one testcase.

Tests _must_ be able to run as non-root and on non-intel platforms,
otherwise the enumeration is busted (since QA enumerates testcases on
a gpu-less xeon box).

The kernel will round it, so if we don't we'll have a spurious

I got kms_flip in hung state with the backtrace below, while the parent process
waiting for the signal helper to exit. It was quite easy to reproduce the bug
by running
kms_flip --run-subtest=flip-vs-dpms-off-vs-modeset
With the change I couldn't reproduce it.

The goal of this test is to ensure that we respect inter ring
dependencies. A more detailed description of what it tests is in a
comment.
The tests relies on having a blit function for the ring, so is currently
only checking synchronization between the render and blitter ring.
v2: Actually create an inter-ring dependency by making the first copy on
ring2 and the second on ring2, not both on ring2.
