Remove teletext support

Browse Source 
Teletext requires special OSD support. Because I can't even test
teletext, I can't restore support for it. Since teletext can be
considered ancient and obscure, and since it doesn't make sense to keep
the remaining teletext code without being able to use it, I'm removing
it.

Choose the quality of the JPEG compression (< 60 recommended for full
size).
tdevice=<value>
Specify TV teletext device (example: ``/dev/vbi0``) (default: none).
tformat=<format>
Specify TV teletext display format (default: 0):
:0: opaque
:1: transparent
:2: opaque with inverted colors
:3: transparent with inverted colors
tpage=<100-899>
Specify initial TV teletext page number (default: 100).
tlang=<-1-127>
Specify default teletext language code (default: 0), which will be
used as primary language until a type 28 packet is received. Useful
when the teletext system uses a non-latin character set, but language
codes are not transmitted via teletext type 28 packets for some
reason. To see a list of supported language codes set this option to
-1.
hidden_video_renderer (dshow only)
Terminate stream with video renderer instead of Null renderer
(default: off). Will help if video freezes but audio does not.
