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.

Let's see if the directory is stable when just one client is looking.

A small bump to try again in the face of delayed appearance of directory
entries.

The client id used is a cyclic allocator as that reduces the likelihood
of userspace seeing the same id used again (and so confusing the new
client as the old). Verify that each new client has an id greater than
the last.
v2: Use (int)(b - a) > 0 to handle wraparound

An earlier client from an old test may still be lingering and disappear
as we scan the sysfs. Be graceful and let it go without tripping over it.

To kick RCU, we go to sleep and hope the system finishes a RCU grace
period before returning. Use sched_yield() in place of usleep(0) to
encourage a pass through schedule().

Compare the runtime against the centre of the read_runtime, to try and
compensate for scheduling delays.

If even the CPU is too slow to submit at the require rate to generate
the workload, skip the test.

Do a few more executions to make sure idle <-> transitions are

CI is not nearly as instantaneous as we would ideally like, and so we
need to compensate for the delays in execution.

In the split clients, focus on comparing the relative runtimes of the
two clients match our expectations. Under CI debug conditions the
overhead of each switch is too large to make accurate estimates.

We only expect to timeslice if there are more than one client available

For the smaller splits, an absolute error is a much greater relative
error so increase the relative tolerance.

We store every client name, pid and runtime under sysfs. Better check
that matches with the actual client.
