Even if we ignore the double-accounting bug in Linux, we need to be sure
that the remaining swapspace is adequate for running our test as the
system may be under load before we even start.

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.

Otherwise we'll hit an igt_skip in the exit handler, which upsets

The goals here are:
- Reduce duplicated code in each KMS test
- Provide an API that looks more like what we want for atomic
modesets. The hope is then that it'll be easy to switch, at
run-time, between the "legacy" path and atomic modesets, keeping
the same API for tests.

We need to first check whether we'll even run the testcase before
deciding to print a premature SKIP/FAIL. Without this and global
skipped resulted in superflous output when running only one testcase.

I got kms_flip in hung state with the backtrace below, while the parent process
waiting for the signal helper to exit. It was quite easy to reproduce the bug
by running
kms_flip --run-subtest=flip-vs-dpms-off-vs-modeset
With the change I couldn't reproduce it.
