Simple check which acquires buffer objects from gem-pool. It verifies:
- object reuse (previously created is completed in execbuf)
- object creation (submitting batches when spinner is executing).

Test verifies that intel-allocator uses caller default-alignment setting
during open() instead of choosing safe alignment instead. Also check
does alloc() can overwrite default setting used by the allocator.
v2: rename allocator -> default-allocator test name

For DG2 and beyond regions alignment may vary so many tests would need
to be rewritten to handle this constraint. As Ashutosh noticed most of
tests can use safe alignment as a default.
Adopt intel-allocator to use safe or user defined power-of-two alignment.

Subtest standalone uses igt_fork macro and after that makes
checks of work done by children processes, but this macro start
counting from zero, it never touches index 2. Correct indicies,
comment and asserts accordingly.
This wasn't observed in CI due to HIGH_TO_LOW strategy used as
default in allocator so first obtained offset was never zero.
v2: correct comment, indices and checks (Zbigniew review)

Test creation and usage of allocators in multiprocess mode
for contexts shared with the parent process as well as
private for the child.
This new test discovers a bug in the allocator implementation:
allocator is not correctly initialized if it is opened by
a child process using its private file descriptor.

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.

To use spinners with no-reloc we need to alloc offsets for them
from already opened allocator. As we don't know what strategy
is chosen for open (likely HIGH_TO_LOW for SIMPLE allocator) we
want to overwrite it for spinners (there's expectation they
will reside on low addresses).
Extend allocator API adding intel_allocator_alloc_with_strategy()
to support spinners rewriting.
v2: add change in api_intel_allocator test to compile properly
whole series.

Sometimes we don't want to use common allocator provided by main IGT
process. Verify it is able to "detach" from it and initialize its own
version of allocator.
