Reworked OSD Volume handling and display of volumebar. Run make stamp-api to update include/vlc_symbols.h.

may close #163

Use ALSA or tell aRts to use ESD and use ESD in VLC, or fix it.

Change locale (LC_NUMERIC) in appropriate places so we always use the
user's locale when reading/writting floats to config (otherwise it would
read floats using C locale (float separator is . in C) and write them
using the user's local (float separator can be , instead of .))

If these changes aren't ok, then i think that the only solution would be
to always setlocale(LC_NUMERIC, "C") when handling config str<->float
conversions.

- Compiler warning fixed

(carriage return are forbidden).

Now can update PO when compiling from subdir

   doesn't care to fix their packageconfig stuff to be really useful (such
   as instructing to link with mp3lame, zlib, etc.), so the
   packageconfig stuff doesn't bring much, and the current code breaks
   under OS X and Cygwin (at least).

and some other Makefile cleanup

   than [12145]. We just want to replace spaces.
 * include/network.h: Restored the previous behaviour of vlc_UrlEncode().
   We really mean to URL-encode ? & / etc. in order to be able to pass
   a string containing those special characters as a GET variable in the
   http control interface.

If you want them, take them back from the svn attic, fix them and reintroduce them. I didn't remove the configure.ac snippets, they are still in but commented

closes #311

   another file. Also reduced MAX_DIR_PATH_LENGTH to 2560 since
   allocating anything larger than 4kB on the stack is likely to break
   on many OSes.

   replace spaces with '+'. That's what browsers do, and I think it's
   the right thing to do since vlc_UrlEncode was just breaking things.
   refs #90 and debian bug #279735

   [12140].

   variables : program, title, chapter, audio-es, video-es and spu-es.
   New RPN function "value 'variable' vlc_set_var" to change the input
   variables (variable can be any of those above).
