Chris Wilson 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.
