Squashed VLC_TRUE fix

Fix decoding of teletext in ps files (the zvbi decoder expects the full PES packet, I haven't been able to test the telx.c decoder yet as I don't have any ps file with teletext subtitles available).

Code cleanup without semantics changes
Resets the reference count when returning a previously allocated picture
Check error path

In the meantime, another module (like the mosaic_bridge hack) could call it.
Instead, increase the reference count to be sure it won't be destroyed.

Some cleaning too.

Could go badly wrong on platforms without atomic 64-bits access

In this case, volatile was both incorrect (volatile does nothing about
thread synchronization) and not required (there is an explicit lock).

Fix blinking on redraw in ncurses interface... if anyone has an idea about why that call to clear() was needed ... (And remove a bunch of trailing spaces)
