lib: Open debugfs files for the given DRM device
with fixes.

This reverts commit 301ad44cdf1b868b1ab89096721da91fa8541fdc.
When a render-only device is opened and gem_quiescent_gpu is called, we
need to use the debugfs dir for the master device instead.

When opening a DRM debugfs file, locate the right path based on the
given DRM device FD.
This is needed so, in setups with more than one DRM device, any
operations on debugfs files affect the expected DRM device.
v2: - rebased and fixed new API additions
v3: - updated chamelium test, which was missed previously
- use the minor of the device for the debugfs path, not the major
- have a proper exit handler for calling igt_hpd_storm_reset with the
right device fd.

The number of vblanks that pass whilst we read back the CRCs is depended
upon CPU scheduling -- we may take longer than expected and end up
reading more CRCs. Align the start of the loop to a vblank.

Even when the running kernel does not support selftests, make subtest
enumeration list known kselftests. The list is generated using
selftest listing headers copied from the kernel.
If the running kernel gains new selftest subtests, they are listed
even without copying the headers over and rebuilding IGT.
v2: Use correct names for the testcases

When the memory backing the userptr object is released by the user, but the
BO itself is not closed, it's possible to trigger recursive deadlock
caused by operations done on different BO mapped in that region.
Testcases are simulating such behaviour by using MAP_FIXED mmap flag.

Recently we added i915_hpd_storm_ctl into i915's debugfs directory,
which allows us to control the thresholds i915 uses for detecting
hotplug interrupt storms from userspace, along with the ability to
entirely disable them. This adds some helper functions into IGT to
enable making use of this feature, along with adding some chamelium
tests for it.

SIGRTMAX appears to be used by valgrind now for its internal tracking,
so avoid it in the helpers.
Also add some valgrind annotations in gem_mmap, to make sure that its
accesses are tracked correctly. I've also added gem_munmap, but there
are a lot of places that don't use it yet in tests/.

The dynamic plane support means that there should never be gaps in the
pipe->planes array. This means we should never need to move the cursor
plane from the last slot to another.
Remove the unnecessary code, and add an assert that makes sure nothing
strange happened that broke the assignment logic.

The dynamic plane support means that if there's no cursor plane, then
there is no space in the pipe->planes array for it, and thus assigning
a "drm_plane-less" plane is out-of-bounds and leads to heap corruption
and later crashes.
The "drm_plane-less" cursor plane isn't included in n_planes anyway,
which means there's no way to ever access it/know that it's there - so
just remove it entirely.

The function igt_kmod_is_loaded() returns the wrong value when there is
a module loaded whose name is a prefix of the name supplied as a
parameter. For instance, if the "snd" module is loaded,
igt_kmod_is_loaded("snd_hda_intel") will return true even if that module
isn't loaded, thus causing drv_module_reload to fail in that scenario.

In upcoming drm-misc-next changes, the number of planes per pipe has
been increased as more than one primary plane can be associated with
a pipe.
The simple fix for this would be to simply bump hardcoded value for
number of frames per pipe.
But a better solution would be to add support for dynamic number of
planes per pipe to i-g-t.
