Add support for rolling headers and clock updates in teletextdec
This patch adds support for rolling headers and clock updates in the teletext decoder's RGBA output mode. Thus, the behaviour is now quite similar to what can be seen with analogue TVs :
- Right after turning on the decoder, only the rolling header is displayed, while the page content is blank.
- After finding the page, only the clock is updated.
- When changing the requested page, the content of the old page is still displayed, but the header shows rolling page numbers.
The patch requires applying the patch porting the teletextdec element to 1.0, which I posted previously.
