This patch adds ioctl-errors subtest to be used for exercising prime sync ioctl

The subtest constantly interrupts via signals a function doing concurrent blit
to stress out the right usage of prime_sync_*, making sure these ioctl errors
are handled accordingly. Important to note that in case of failure (e.g. in a
case where the ioctl wouldn't try again in a return error) this test does not
reliably catch the problem with 100% of accuracy.
v2: fix prime sync direction when reading mmap'ed file.
v3: change the upper bound using time rather than loops

I'm probably blind, but where is the reviewed kernel patch for this? If
it's somewhere hidden, please resubmit with all the whizzbang stuff needed
for merging added ;-)
Thanks, Daniel
You're not blind Daniel :) Chris will be sending the kernel side but
regardless this igt test should be good to go even without the kernel patch.
