Add no-relocation mode for GPU gens without relocations. In WC
mode on discrete dg1 we need to use device_coherent mmap.

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.

Perform fewer iterations as on our very slow skl device, the basic test
is tasking 120s. The basic test is only a cursory scan around boundary
conditions, it is not meant to be exhaustive, just explorative.

igt_require_gem() is a pecularity of i915/, move it out of the core.
Similar opportunistic move of gem_reopen_driver() and
gem_quiescent_gpu().

Skip using the gtt or applying tiling. Instead use the blitter for
detiling on devices without mappable aperture.

igt_aux.h already provides the optimal igt_fls(), so use that in
preference to open coding the brute force version.

The aim of this test is to combine gem_linear_blits, gem_tiled_blits etc
into one test runner that covers investigation into HW alignment issues
as well as driver boundaries (relocs, access, thrashing). This here is
but a start!
See also gem_concurrent_blits which looks for coherency issues between
parallel execution.
