changeset.

* modules/audio_output/directx.c: audio device selection based on a patch from Matthew Armsby (uberground at gmail dot com) + config option to disable float32 output.

* modules/stream_out/transcode.c: better picture heap leaking detection when encoding in multithreaded mode (needed if the encoder doesn't remove the pictures as fast as the decoder put them).

libvlc.c: Print --no-X in help to not confuse users. --noX and --no-X are still parsed and give the same results.

(closes #172)

mozilla devs should really fix bugs ...

* Update NEWS and README with info on the new module.

* modules/access/dvdnav.c, src/video_output/vout_subpictures.c: Use the proper palette for DVD menus.

  main thread (one more step to hopefully fix #45)
 macosx/controls.m: fixed a tiny memleak

* include/vlc_config.h: VOUT_BOGUS_DELAY was way too low, which triggered continuous trashing of early pictures when seeking in some asf files.

* GET_TIME is inaccurate, because it is based on average block duration.
* In case skipping to DVD_MENU_Title fails try DVD_MENU_Root. Otherwise we might go directly to the movie instead of the menu, which I find less desirable then viewing the FBI warnings.
