drm: Add some kselftests for the DRM range manager (struct drm_mm) First we introduce a smattering of infrastructure for writing selftests. The idea is that we have a test module that exercises a particular portion of the exported API, and that module provides a set of tests that can either be run as an ensemble via kselftest or individually via an igt harness (in this case igt/drm_mm). To accommodate selecting individual tests, we export a boolean parameter to control selection of each test - that is hidden inside a bunch of reusable boilerplate macros to keep writing the tests simple. v2: Choose a random random_seed unless one is specified by the user. v3: More parameters to control max_iterations and max_prime of the tests.
