* download the SDL stuff from sourceforge instead of the bogus official server, as the SF park is much faster and more reliable (forward-porting [18622])

ts.c, telx.c: Fallback to teletext detection if TS detection wasn't possible

   for different languages. Slightly changed the way the dvbsub parser
   works to allow correct streaming with --sout-all or --programs.
 * modules/mux/mpeg/ts.c: Changes to allow descriptor pass-through with
   telx and dvbsub. This is kind of kludgy.
 * module/codec/telx.c: Got rid of the ugly static variables and use 
   info from the TS demux.

- the stream provided by thedj containing some kind of VPS informations know works fine (they aren't displayed as subtitles anymore). It also solve the same issue on two examples streams on the vlc file repository (called stream-demux-telx-1.dump and stream-demux-telx-2.dump)

- got rid of a kludge that used to be necessary on the "has-subtitles.ts" example stream to avoid subtitles disapearing too fast in some cases. I don't know exactly why it's not anymore necessary, probably because I handle better the subtitle flag now.

- now the page number is handled independently for each 8 magazines

Remove useless test i_chunk is uint32_t and cannot be lower then zero. This fixes a compile warninig and hopefully doesn't introduce an mp4 problem. Test your mp4's.

Revert part of rev 18553 where p_track->i_chunk test has changed. It shouldn't have gone in this commit.

 - out of bound read initially uncovered by sam,
 - also malloc() can really return NULL for arbitrary large alloc,
   return value MUST be checked.

* give credit to Jean-Baptiste le Stang for the UB script, add it to the source bundle and update authors a bit

* commit Jean-Baptiste's universal binary script to svn, so you don't have to browse trac each time you need it. remember to customise the 3 variables at the top before using it. (closes #749)

* applied Westacular's patch with minor modifications, which solves some issues with this script in certain situations and lets the Finder do most of the work. Note that this script isn't 10.2-save anymore and triggers the Finder to launch in case that it is closed. (closes #911)

Added option to disable session timeout option on RTSP request (use: --rtsp-session-timeout=-1 to disable this option, >= 0 to enable it, default is 5). Patch from Saso Kiselkov (skiselkov at gmail dot com) for making VOD (RTSP) work with HanunTech STBs, with modifications from me.

* design change: the current volume is automatically stored on quit now and restored on first playback of the next run, similar to other major media players (closes #989)
