bd292436ed lib: Avoid assertion if sig_ioctl is unsed from a child accidentally
The timer is tied to the creator thread, i.e. it is not inheritable
across fork() or clone()/pthread_create(). Using it thus causes an
assertion failure in the test after the one that aborts (and so on until
we perform an interruptible test correctly) - one mistake snowballs. We
can stop the snowball by doing an initial check and diverting back to
drmIoctl().

8520037e54 lib: Measure the cost of calling timer_settimer() for sigiter
We wish to delay the first signal from the igt_sigiter_ioctl
sufficiently to skip over the timer_settime() and into the drmIoctl
kernel context before firing. If we fire too early, we will think that
the ioctl doesn't respond to signals and ignore it in future. If we fire
too late, we won't probe the ioctl for signal handling at all. Let's try
measuring the timer_settime() call time as a first approximation.

d545610861 lib/igt_aux: Divert ioctls for signal injection
To simplify and speed up running interruptible tests, use a custom
ioctl() function that control the signaling and detect when we need no
more iterations to trigger an interruption.

We use a realtime timer to inject the signal after a certain delay,
increasing the delay on every loop to try and exercise different code
paths within the function. The first delay is very short such that we
hopefully enter the kernel with a pending signal.

Clients should use

struct igt_sigiter iter = {};
while (igt_sigiter_repeat(&iter, enable_interrupts=true))
	do_test()

to automatically repeat the test until we can inject no more signals
into the ioctls. This is condensed into a macro

igt_interruptible(enable_interrupts=true)
	do_test();

for convenience.

c1fed522ae lib: Replace drmIoctl() with a layer of indirection
Insted of calling drmIoctl() directly, call igt_ioctl() instead. In the
normal scenario this is function pointer that calls drmIoctl() (so no
penalty), but allows us to divert ioctls into our own routines for
nefarious purposes. One such purpose will be to control interrupt
generation into the ioctl, to be able to detect when we successfully
interrupt the ioctl and when we no longer need more interrupts.
