Promote intel_os.c helpers to igt_os.c, so that I can re-use them for
some additional msm tests. Just big churny rename, no functional change.

Add typechecking to the min/max macros and make their locals truly

Add a wrapper for gem_create_ext ioctl (a version of gem_create that
accepts extensions). In preparation for the driver change implementing it,
a local definition of its id and necessary structs have been added,
which are to be erased as soon as those definitions
appear in the i915_drm.h file.
The new ioctl wrapper is added to a separate file.
For consistency the wrapper of the old ioctl, gem_create
is moved from ioctl_wrappers to gem_create.

igt_require_gem() is a pecularity of i915/, move it out of the core.
Similar opportunistic move of gem_reopen_driver() and
gem_quiescent_gpu().

If the kernel improves upon its O(N^2) alignment search, it can easily
fit a few GiB of buffers into the GTT within the expected minimum run
time. Instead of hardcoding the expected bad behaviour, our assertion is
that the naughty client does not hinder the normal client, so directly
compare the two execution times. The normal client should not be doing
any work, so we never expect it to take more than a few microseconds...

Instantiating the objects can be surprisingly, worryingly slow; even on
big core LLC devices. Rather than worry about that and cause timeouts in
simply setting up the test, apply a limit to the setup time so that we
only use the amount of objects instantiated within the first 20s.
Due to the quadratic behaviour being exposed by the test, this may not
entirely eliminate the timeouts -- but at least the timeouts should then
be for the right reason.

The premise of the test is that one client does not block the other, to
which we only need to verify that the ready client proceeds unhindered
by the abusive client. So we only need assert that the ready client
completes within a shorter time than the abusive client.
It would be nice that we could assert that under all conditions it never
takes more than a millisecond to submit a no-op; but that goal is a bit
too far for today.

A low priority client should not block a high priority client. In this
case we check that if a low priority client poisons its own GTT and so
its execbuf may take ages to process, a high priority client can still
execute in parallel.

We can already move all the tests with distinct prefixes: gem_, gen3_
and i915_.
pm_ and drv_ tests will follow in batches, so we can do the
adjustments in the reporting/filtering layer of the CI system.
