* include/vlc_common.h: added the UI64C() macro for unsinged long long constants.

* src/playlist/playlist.c: vout/sout garbage collection improvements.

* modules/access/cdda/access.c: fix to allow playing the last track and cd's with only 1 track.

* src/misc/threads.c: fixed a Darwin-specific bug introduced recently

* configure.ac: added an --enable-utf8 option (default enabled on osx/beos/win32).
* src/libvlc.c, modules/gui/wxwindows/wxwindows.h: use #ifdef ENABLE_UTF8

reading. (caught by valgrind).

* po/*: ./toolbox --update-po.

* modules/demux/playlist/Modules.am: don't forget playlist.h.

* ALL: preparation for 0.7.1-test2.

* modules/stream_out/transcode.c: fixed memleak. Set aspect ratio info even for raw video input.

* include/charset.h: added "extern "C" {" for c++ modules.
* modules/mux/mp4.c, modules/demux/ts.c: fixed memleaks.

* modules/codec/ffmpeg/encoder.c: make it ffmpeg-0.4.8 friendly.

* configure.ac: what about checking for the c++ preprocessor.

* modules/demux/a52sys.c: forgot to remove this file.
* modules/audio_output/alsa.c: kind of a work-around for a strange bug that trashes the stack. Doesn't solve it but should be easier to track down now.

  - new ffmpeg options available from the command-line : interleaved video,
    noise reduction, rate control parameters, i_quant_factor, trellis
    quantification, mpeg4 matrix, and thread count
  - portable functions to use ffmpeg multithreading capabilities on all
    platforms
  - hurry up mode now turns off rd and trellis, and also raises the noise
    reduction parameter (thus noise reduction is mandatory with hurry up)
  - if threads=1, no ffmpeg thread is launched, but the ffmpeg encoding
    will be done in a separate thread than the packetizer and decoder
  - fixed a bug with mp3 decoding and weird ffmpeg return code

  exactly once.

  OSes, and added an rt-offset configuration variable to tune the priority
  of VLC against other programs without recompiling everything.

  in the past, to avoid flooding the client.

(no more default values).

Patch from Tim O Callaghan (tim.ocallaghan - AT - limestudios - DOT - com)

  - fixed the bug with the modules not setting up their prefs.
  - bugs: int with strings items are broken (see relfontsize)
  - hotkeys elements don't really work

Tell FAAD2 to produce FAAD_FMT_16BIT (16bits PCM values) and VLC so that it doesn't need to do a conversion filter for it.
