- Order : if a then b are initialized, release b then a ;
- Typos ;
- Cosmetic changes.

- Added vlc_mutex_destroy and vlc_cond_destroy function, for pthreads.
- Used them before quitting, every lock and cond is destroyed
- Checked the return value of malloc and realloc in input_programs
- Cosmetic changes

TODO: add vlc_*_destroy for beos and C_thread

 . should compile & run on Solaris with ./configure --disable-dsp
    (tested on puma)
 . removed most SYS_SOLARIS #ifdef's in favour of more generic tests
 . updated example ./configure line in INSTALL file
 . now we only load modules that end with ".so"
 . null module is compiled by default

Fixed a typo than prevented from building ...

Fixed initialization of payload_start and payload_end
It should be finished now.

* --enable-sdl and some others are now --with-sdl[=name] to supply an
optional library name ;
* deleted all unnecessary #include <sys/uio.h> ;
* /usr/include is now searched when looking for libraries and headers.

It seems to compile and run on BSD. Under Linux Sam's latest commit makes
vlc crash on startup, so I can't really tell, but hey it compiles.

 . src/misc/modules.c is in a workable state now.

  To test it, run ./configure with the --enable-null flag, which will
  compile the Null Module as a plugin. Watch the memory usage at the
  launch and when the plugin is released.

(previous commit foired)

 . this is a coding style patch which removes all "foo(bar){" constructions
   and most of the tabulations.
 . also, fixed a bug in the default subtitle track.
 . and made a few error messages more explicit, ie. changed "error: %s" to
   "foo error: couldn't initialize bar (%s)"
 . and removed a warning in intf_ctrl.c which isn't used anyway.

 . splitted modules.h into modules.h and modules_core.h to enable
    clean compilation of the Null Module.

 . added the Null Module, the module that does nothing but that is going
    to be of great help for debugging my module code.

 . Added files needed for the forthcoming module management.

 Notes:

   Plugins are now called modules, because we will be able to compile
   them either as a dynamic plugin, or within the program. And, more
   important, I can commit this without having to break the vlc :)

   I tried to be as clear as possible in my comments, please tell me
   if a few prototypes still have an unclear beahaviour.

   Current features:
    . none, files haven't even been added to the Makefile yet.

   Future features:
    . dynamic loading (done)
    . built-in modules (still to do)
    . automatic unloading of plugins (done)
    . dynamic configuration (still to do)
    . automatic choosing of the most appropriate plugin for a given
       task (still to do but well prepared)

  - fixed segfault, it was probably a memory corruption but I'm not sure :) ;
  - video_output.c : compute picture size even if b_need_render == 0;

grrrr, I'll kill someone) ;
* Put config.h in front of others in audio_decoder.c.

 . added a few missing break;s
 (oui je sais je ne fais que des patches de deux lignes � trois balles,
  mais par telnet c'est pas facile)

- Removed i_iovec_start and i_iovec_end. Used i_data instead
- Meuuh : some questions for you in the commentaries

Happy new year !

* Fixed a bug in vpar_headers.c synchro handling introduced before ;
* Enhanced synchro's handling of dates and frame structure changes.

NB : b_has_pts has disappeared for brevity reasons, use i_pts != 0 instead.

 . avoid calling SafeRead() with a null packet size.

* Changed behaviour of preparsing code, faster startup ;
* Fixed DecodePSM(), cannot test ;
* Cleaned up ParsePES(), fixed a bug which could reject very small but
  valid PES packets ;
* Fixed cosmetic bugs in vpar_synchro frame_rate display.

 . SPU decoder now uses Meuuh's GetChunk() code.
 . lots of cleaning in the SPU decoder.
 . message queue is flushed before we spawn input.
 . fixed so that it compiles with VDEC_SMP (no good sync yet though).

* Fixed a bug in -c and -s options.

 . fixed AC3 and SPU PES reading (ph34r da one-byte patch)
 . some 79 char wrap.

 . no need to add "\n" at the end of intf_*Msg() messages anymore.

* Fixed an segfault in input_programs.c ;
* Added -fomit-frame-pointer optimization.

  be the last one.
