In few tests we got some MI_* duplicates (MI_MATH for example).
Add common definitions in intel_reg.h and remove local definitions
in the tests.
v2: Definitions MI_LOAD_REGISTER_MEM_GEN8 was removed so from now
on user will need to encode length on it own. :

In 4d9396e67930 we have started storing the opts with which the spin was
created as part of igt_spin_t. The ahnd stored as part of igt_spin_t is
therefore redundant. We can get ahnd from opts.ahnd.

The function names gem_has_guc_submission and gem_has_execlists and
gem_has_semaphores are ambiguous. After "lib/i915: Return actual submission
method from gem_submission_method" these functions return which submission
method the kernel is actually using, not merely one which is
present (e.g. execlist submission is present on all kernels on which GuC
submission is present).
Therefore change the function names to clarify that they return the actual
submission method being used, not merely one which is present.

gem_submission_method() purports to return the currently used submission
method by the kernel, as evidenced by its callers. Therefore remove the
GEM_SUBMISSION_EXECLISTS flag when GuC submission is detected.
This also fixes gem_has_execlists() to match its description, previously
gem_has_execlists() would return true even if GuC submission was actually
being used in the driver.
v2: Or gem_has_execlists call-sites with gem_has_guc_submission to make the
new code equivalent to the previous code.
v3: Clarify that submission method is either guc (0x4), execlists (0x2) or
legacy without semaphores (0x0) or legacy with semaphores (0x1)
v4: Submission methods are now clearly defined as one of guc (3),
execlists (2) or legacy ring buffer (1)

For newer gens we're not able to rely on relocations. Adopt to use
offsets acquired from the allocator.

v2 (Jason Ekstrand):
- Rebase on Tvrtko's changes
- Fix an issue in default-virtual with the set-once rule for engines
v2 (Ashutosh Dixit):
- Use SINGLE_TIMELINE in far_delay()
- Assert tmp_ctx->id != 0 in far_delay()
- Call intel_ctx_destroy()

Test incorrectly assumes no modparam means default expiry, while in
reality no modparam means old kernel / de-selected feature in which
case test should skip.
v2:
* New line. (Petri)

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.

Test to demonstrate a problem with the proposed default fence expiry
semantics where long rendering chain get silently broken.
If we had fence error propagation (no clear agreement whether to do it or
not) maybe userspace would see if, assuming fence status is looked at, but
overall potential rendering corruption is the story in any case.
Note that this is not a single long batch but just a long queue of work
which could be viewed as heavy system load as well (like virtualisation
or other types of resource sharing).
v2:
* Fix commit message.
* Blacklist the test which is expected to fail for now.
