A more complicated store variant to stress inter-engine dependencies
(i.e. semaphores and sync). We write a control value from one batch into
the next and then execute it. This is repeated a few times with each
execution happening on a different engine (so the kernel has to
serialise operations between engines) until we finally write the value
out into our scratch buffer where we can check the result, just like a
Chinese whisper.

The execbuffer2 ABI is not strictly limited to a total of UINT32_MAX
entries, rather each object can have a maximum of UINT32_MAX relocation
entries and the current implementation imposes that the total must be
allocable in a contiguous buffer when necessary (i.e as large as the
kernel can conceivably allocate). This is not an ABI constraint per-se,
just an implementation issue.
Whilst updating the limits for 64bit kernels, review usable of
ioctl-wrappers (i.e. use __gem_execbuf now available) and include a
batch of more tests to explore the boundary conditions of the maximum
relocation size. Note that rather than guess the reloc-max, it would be
better if we queried it. Also it is of vital importance that when
constructing a test to fail in a particular fashion, it must not include
any other error (e.g. we were passing in relocation arrays with invalid
target handle and domains when looking for a potential overflow across
multiple objects).

Instead of just giving preference to an eDP primary connector, give
preference to one that's eDP and supports pipe A, then try lesser
optimal combinations later.
We could try to make our test suite use different sets of connectors
when testing FBC and PSR, but that would require some rework, and we
would still be helpless when testing the combination of FBC+PSR.
Also notice that we still hardcode pipe A for the primary connector,
regardless of whether it supports it. This will be solved in the next
commits.

The hangcheck logic will not flag an hang if acthd keeps increasing.
However, if a malformed batch jumps to an invalid offset in the ppgtt it
can potentially continue executing through the whole address space
without triggering the hangcheck mechanism.
This patch adds a test to simulate the issue. I've kept the test running
for more than 10 minutes before killing it on a BDW and no hang occurred.
I've sampled i915_hangcheck_info a few times during the run and got the
following:
