This addition to the v4l2-api add definitions for the constants and
data structures used for sliced VBI data insertion into MPEG streams triggered
by V4L2_MPEG_STREAM_VBI_FMT_IVTV.  This simply declares what the ivtv and
cx18 drivers and MythTV have already been doing and provides a proper data
structure definition to user space.

The exported copy of videodev2.h contains this line:

	#define #include <sys/time.h>

This is because for some reason it defines __user for itself -- despite
the fact that we remove all instances of __user when exporting headers.
_All_ pointers in userspace are user pointers. Fix it by removing the
unnecessary '#define __user' from the file.

The new headers ivtv.h and ivtvfb.h would have the same problem... if
whoever put them there had actually remembered to add them to the Kbuild
file while he was at it. Fix those too, and export them as was
presumably intended.

Note that includes of <linux/compiler.h> are also stripped by the header
export process, so those don't need to be conditional.
