This test case introduces concurrently running test cases for atomic
modesetting.
The first test or thread draws blue backround with black holes on it.
These holes are covered by rectangular, blue planes that are placed
randomly like in test case 'kms_plane_multiple'.
The second thread changes resolution from higher to lower one and back.
For: VIZ-7022
v2: use igt_fork instead of pthreads to create concurrent test runs (Maarten)
v3: use igt_display calls instead of raw drm calls for display updates (Maarten)
Various cleanups on accessing drm connector (Maarten)
