but it is even more ugly than before

(da big courmischage)

   available for all platforms.
 * modules/access_output/udp.c: Now runs the output thread at
   VLC_THREAD_PRIORITY_HIGHEST

   priority thread, since these functions use an internal mutex and may
   delay the thread for up to 100 ms under heavy loads (experienced with
   the mosaic). Instead we now recycle the UDP buffers, which is
   incidentally faster than malloc()/free(). It should avoid "late
   buffer sent" messages. Also removed the --sout-udp-late option because
   "better late than never" (I changed my mind on this).

  single UDP frame (may disturb some decoders).

  at once. This requires the export of the PCR block_flag.

Fix a bug with preferences
Added some more names
Use shortname to store the name

* Each module can declare a "human-readable short name" with set_name
* Modules are sorted by category (set_category, set_subcategory).
  Modules configs can be separated by set_section()
* Separated audio-filter and audio-visual
* Separated extraintf and control
* New command and widget : add_module_list() for comma-separated modules
* Vfilters now use "," as separator

* modules/access_output/udp.c: if a packet is bigger than the mtu size, we emit a warning and try to split it.

 (udp-sout-caching has been renamed sout-udp-caching).

 Too late packets according to this value are trashed. By default it is
0 ie don't trash any packets. (I think it's safer, else we may have too
much people complaining about broken picture or CSA not working anymore ;)
The drawback is potential floods of clients...

* ALL: changed the prototype of module_Need() to accept a "strict" boolean argument.
If "strict" is true and a module name is provided then module_Need() will only look for the specified module
If "strict" is false, then module_Need() will first look for the specified module and if it wasn't found, will continue with the other modules with the same "capability".

  packets at once (less scheduling overhead) ; typically access=udp{group=5}
  will send 5 * 7 TS packets at once.

   + lower a bit the input thread priority on win32 (using THREAD_PRIORITY_ABOVE_NORMAL now).
* modules/access/file.c:
   + s/config_GetInt()/var_Get() for file-caching.
* modules/access_output/udp.c:
   + less verbose debug messages.
   + increase thread priority on win32.

  in the past, to avoid flooding the client.

* ALL: removed useless add_category_hint().

* src/stream_output/stream_output.c, include/stream_output.h: new sout_AccessOutRead() funcion.
* modules/access_output/file.c: implemented sout_AccessOutRead().
* modules/access_output/udp.c: coding style cleanup.
* modules/mux/mp4.c: Added support for generating "fast start" files (ie. with the moov header at the beginning of the file).
   Started some code cleanup.

* modules/mux/mpeg/ts.c: new dts-delay option to add delay between the
  PCR and the DTS of the current frame.
  When deleting a video or audio stream (in case of PMT change), the
  new video and audio ES will take again the pid-video and pid-audio if
  they have been specified.

  pthread systems (activate with --rt-priority)
* modules/access_output/udp.c: Only discard packets which are _very_ late

fill packet send to mtu size, needed by rtp)

 "caching".  (ex: udp{caching=ms})

setting (in fact only used by access_out/udp.c.

* modules/access_output/udp.c: removed unnecessary code.

* modules/access_output/udp.c: implemented a caching mechanism which solves all the bad quality streaming issues that have been reported. The caching value can be modified with the --udp-sout-caching config option (the default value being DEFAULT_PTS_DELAY ==  300 milisec).

     wait or we will face delay issues as reported in #794. Fix inspired from
     a suggestion by John Michael Zorko.

* modules/access_output/udp.c: Now supports IPv6 IP addresses (patch

* po/*: Updated po files to send out to the translators
* Mac OS X port: Cosmetics
