Some i915.ko features have very nice IGT tests, which are never
executed because the features are disabled by default. This leads to
unnoticed regressions both in the Kernel and in the IGT tests. We
have seen this multiple times, for example, on FBC and PSR.
We want to be able to run IGT and actually test these
disabled-by-default features in order to make sure we at least don't
break them even more. Sometimes they may be disabled for some specific
reason, and we don't want to increase the set of reasons without
noticing.
To help solving this problem, this commit adds some helper functions
that should make it easier to change certain i915.ko parameters and
then restore their original values at the end of the test. With this,
I'm hoping QA will be able to detect any regressions and automatically
bisect them - or, with PRTS, reject the patches before they are even
merged.

Just a little helper for code that needs to wait for a certain
condition to happen. It has the nice advantage that it can survive the
signal helper.
Despite the callers added in this patch, there is another that will go
in a separate patch, and another in a new IGT test file that I plan to
push later.
v2: Check COND again before returning in case we hit the timeout.

This is an extention of igt_debug_wait_for_keypress that also can have
customized message and return key pressed.
v2: This is actualy a v2. V1 was an extension of original
igt_debug_wait_for_keypress but it was nacked.
v3: Make [Y/n] check inside aux function as suggested by Daniel.
Also renaming and adding first use case along with the axu function.
v4: Simplify function name and make it assert pressed key
is different from n/N as suggested by Daniel.

intel-gpu-tools currently has a bunch of tests for suspend,
but currently none (that I could find) for hibernate.
Attached is a rudimentary patch to add said test. It does so
by repurposing the drv_suspend driver to handle both suspend
and hibernate, since the difference is miniscule.
I decided to split the suspend/autoresume functions in
igt_aux.c though, to be able to leave the igt_system_uspend_autoresume()
function unchanged (the other option would be to
introduce a boolean function argument and have that
decide what parameters to pass to rtcwake).
The timeout passed to rtcwake probably needs tuning (it might
even need to be dynamically adjusted, since the time hibernation takes
varies wildly depending on the amount of non-cache memory in use).

Also move forcewake and stop_rings code from igt_debugfs to igt_gt
since it fits better. And move the hang injection fork helpers from
igt_aux to igt_gt, too.
Also push the intel_gen call into igt_hang_ring while at it.

Add a function to lock memory into RAM and use it in the
gem_tiled_swapping test to reduce the amount of allocated memory
required to force swapping. This also reduces the amount of time
required for the test to complete, since the data set is smaller.
The following durations were recorded with gem_tiled_swapping on a
haswell system before the change:
Subtest non-threaded: SUCCESS (55.889s)
Subtest threaded: SUCCESS (810.532s)
and after:
Subtest non-threaded: SUCCESS (11.804s)
Subtest threaded: SUCCESS (268.336s)
v2: add various assertions and requirements and make sure
gem_tiled_swapping works on systems with less RAM (Daniel Vetter)
v3: fix allocation size calculation

If we don't enable audio runtime PM, the audio driver won't release
its reference, the refcount won't ever become zero, so we will never
actually runtime suspend. So move this code from pm_rpm.c to
igt_aux.c, so kms_flip - and any other IGT test case using RPM - can
benefit from it.
Previously, if you ran pm_rpm before running the other tests - or if
you just didn't have snd_hda_intel loaded - you wouldn't notice this
bug.

If the signal helper is active, the usleep() calls return earlier, and
we may end up returning false way before the 10s timeout, failing the
subtests. This currently happens on the kms_flip RPM interruptible
subtests.

With the structured logging it makes more sense to tune this down a
bit. Also, this way it is consistent with Thomas Wood's new activity
indicator helper.
Spotted while discussing Thomas' patch with him.
v2: Thomas noticed that I've forgotten the fflush. Extract
igt_interactive_info for both igt_progress and igt_print_activity.
v3: Interactive output should go to stderr. Also extract the "is this
a terminal" check.

- Use keys in just one env variable to enable/disable it.
- Add an informational message so that the users knows when to press
the key (more useful over ssh than when run on the terminal ofc).
- Improve the documentation so that it's clearer how to use this
when running tests.
