* the dts/ac3 changes fix some files from http://samples.mplayerhq.hu/evob/ and some other sources.
   * MLP doesn't have any know free decoder (nor do i have any sample) so this is basically "for the future"
   * VC1 doesn't work ... most likely needs some more changes to the code.
 * remove trailing spaces

add new filename_sanitize and path_sanitize functions to remove forbidden charcters from filenames/paths and use where appropriate.

Repairing some sources links.
Add a "make source" process to get all the tar.(bz2|gz) in one dir.

Patch by Cedric Coquebert.

   of the teletext descriptor by some French channels.

Patch to force alignment in OpenGL if it isn't correctlt positionned before, as panoramix does do it correctly. Patch By Cedric Cocquebert.

When no start display time is found in a subpicture then return with an error message. Problem reported by: Hytham Alihassan.

Update freetype from 2.1.9 to 2.3.0. This has been tested on veda, espilon, altair, altair/sid-id386/Mingw32.

* 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
