[media] Feature removal: V4L2 selections API target and flag definitions 



After unification of the V4L2 and V4L2 subdev selection targets and flags
the old flags are no longer required. Thus they can be removed. However, as
the API is present in a kernel release, this must go through the feature
removal process.

----------------------------



What:	V4L2 selections API target rectangle and flags unification, the

	following definitions will be removed: V4L2_SEL_TGT_CROP_ACTIVE,

	V4L2_SEL_TGT_COMPOSE_ACTIVE, V4L2_SUBDEV_SEL_*, V4L2_SUBDEV_SEL_FLAG_*

	in favor of common V4L2_SEL_TGT_* and V4L2_SEL_FLAG_* definitions.

	For more details see include/linux/v4l2-common.h.

When:	3.8

Why:	The regular V4L2 selections and the subdev selection API originally

	defined distinct names for the target rectangles and flags - V4L2_SEL_*

	and V4L2_SUBDEV_SEL_*. Although, it turned out that the meaning of these

	target rectangles is virtually identical and the APIs were consolidated

	to use single set of names - V4L2_SEL_*. This didn't involve any ABI

	changes. Alias definitions were created for the original ones to avoid

	any instabilities in the user space interface. After few cycles these

	backward compatibility definitions will be removed.
