modules/codec/ffmpeg/video_filter.c, modules/audio_filter/format.c, normvol.c: added Id svn keyword.

* src/video_output/vout_intf.c, modules/video_output/opengl.c: we do really need these, so please don't remove them again.

* modules/stream_out/transcode.c: use picture ring buffers to avoid leaks due to decoders not releasing pictures properly and to avoid uncessary mallocs.

* modules/gui/wxwindows/video.cpp: reverted change to re-use the video window as it doesn't work well on wxGTK.

* src/extras/libc.c: provide iconv facility in the core (vlc_iconv_open(), vlc_iconv(), vlc_iconv_close()).
* modules/misc/freetype.c, modules/codec/subsdec.c, modules/gui/skins2: use iconv from the core.

     and add callbacks if they already exist

Split out callback routines. 
Some cleanup. Still largely broken though. 

mtime.h: define constant for second-to-millisecond conversions.

po/*: updated the po-files
THANKS: updated my mail-address

vlc_meta.h: added CD-Text, ISO 9660, and CDDB fields. Separate email
will be sent about this.

Note: sound may be off by 2 seconds (150 sectors or pregap
amount). The sound for both this and the other cdda plugin don't work
for me. Before the last SVN update though that's what it sounded like.
