drm/i915/uapi: introduce drm_i915_gem_create_ext
Same old gem_create but with now with extensions support. This is needed
to support various upcoming usecases.
v2:(Chris)
- Use separate ioctl number for gem_create_ext, instead of hijacking
the existing gem_create ioctl, otherwise we run into the issue
with being unable to detect if the kernel supports the new extension
behaviour.
- We now have gem_create_ext.flags, which should be zeroed.
- I915_GEM_CREATE_EXT_SETPARAM value is now zero, since this is the
index into our array of extensions.
- Setup a "vanilla" object which we can directly apply our extensions
to.
v3:(Daniel & Jason)
- drop I915_GEM_CREATE_EXT_SETPARAM. Instead just have each extension
do one thing only, instead of generic setparam which can cover
various use cases.
- add some kernel-doc.
