Now that we have better ioctl wrappers, let's make us of them. The
advantage should be in improved error reporting in case
gem_quiescent_gpu() ever fails.

The drm_open_driver*() functions replace the drm_open_any*() functions and
provide the same utility, but in a way that is platform agnostic, not
intel-specific. This opens the path for adopting intel-gpu-tools to non-intel
platforms.
This commit renames the calls and adds the chipset parameter which can be used
to restrict the opening to a specific hardware family. For example,
drm_open_driver(DRIVER_INTEL) will only return a valid fd if an intel GPU is
found on the system, along with performing intel-specific initialization stuff
like gem_quiescent_gpu(), et al. If OPEN_ANY_GPU is specified, the first
available drm device of any type will be opened.
Other hardware type flags may be added in the future.
The drm_open_any*() calls are retained as aliases of
drm_open_driver*(OPEN_ANY_GPU) but will be removed in a subsequent patch.

The DRM device id for the igfx is fixed, since there can only be one in
the system. So once we query it for the first time we can safely report
that value on every subsequent request, cutting out a lot of noisy
ioctls from inside tests.

Also move forcewake and stop_rings code from igt_debugfs to igt_gt

Same game as with ioctl_wrappers.c.
To split was rather clean except for the static function
oom_adjust_for_doom. But that was a bug, the calls to it in the
various open helpers should simply be done at init and fork time.
Which was already the case, except for simple testcase. So fix it up.
While at it also start with a small section header for the
documentation.

Also some tiny polish to function interface:
- @caching in gem_set_tiling should be uint32_t to match the ioctl
struct.
- s/size/length/ for gem_write/read.
- move gem_get_num_rings to the other ring feature helpers.
v2: Also demote gem_require_ring from static inline and move it, too.

Apparently there's a bit a need for more verbose output in testcases,
mostly for debugging purposes. At least gem_reset_stats and pm_rps
have a verbose mode.
On top of that we're currently not taking advantage of piglit's "warn"
state all that much. But I think it might be useful for testcases which
are notorious for some kinds of spurious failures, like e.g. the really
nasty timing checks in kms_flip. If we demote some of them to just
warnings we could run the overall tests more often.
Hence this patchs adds a new igt_log function with the three levels DEBUG,
INFO and WARN. Plus a bunch of convenience helpers to keep the test
code tidy.
The level can be set through an enviroment vairable IGT_LOG_LEVEL with
info being the default. Also tests can look at the selected log level in
case they want to run costly debug functions only when needed.
Comments highly welcome, I plan to roll this out over tests which can
use it (not all, imo that's too much churn) once we've settled on the
interfaces/semantics.

This is a remnant from the subtest code before we had proper
fixture blocks. With those there's no no reason to have igt_skip
calls outside of fixtures or subtests, so we can assert this and
hence always jump out.
Suggested by Thomas Wood since static analyzers got confused about
this.
To check for fallout I've run all tests as non-root so that they'll
all skip. Only very little fallout resulted.

We need to first check whether we'll even run the testcase before
