This tests the various parts of atomic that I want to make interruptible. Running with --debug shows the stats from __igt_sigiter_continue, which can be used to make sure that we don't fall over. The default igt kms helpers use drmIoctl, which is not intercepted by igt_while_interruptible. Only igt_ioctl is. This means we have to call the ioctls manually here. Changes since v1: - Implement interruptible DPMS checking too. - Use igt_ioctl + igt_while_interruptible, instead of the signal helper shotgun.
