V4L/DVB (6116): ivtv: VBI cleanups and fixes
Besides some VBI cleanups this patch also fixes a subtle problem with the VBI re-insertion stream where the PIO work handler wasn't called quickly enough, resulting in occasional corrupt data. Furthermore the CC output didn't disable CC correctly and at the right time, causing duplicates to be sent. An saa7127 fix for VPS output was also added: the wrong data was sent.
