voroshil 83a2c50ef9 Teletext support for tv:// (v4l and v4l2 only) 
modified patch from Otvos Attila oattila at chello dot hu

Module uses zvbi library for all low-level  VBI operations (like I/O with vbi
device, converting vbi pages into usefull vbi_page stuctures, rendering them
into RGB32 images).

All teletext related stuff (except properties, slave commands and rendering
osd in text mode or RGB32 rendered teletext pages in spu mode) is implemented
in tvi_vbi.c

New properties:
teletext_page - switching between pages
teletext_mode - switch between on/off/opaque/transparent modes
teletext_format - (currently read-only) allows to get format info
(black/white,gray,text)
teletext_half_page - trivial zooming (displaying top/bottom half of teletext
page)

New slave commands:
teletext_add_dec - user interface for jumping to any page by editing page number
interactively
teletext_go_link - goes though links, specified on current page
