es_out.c: handle the pre-roll earlier

- DllRegisterServer modified to use current DLL path when registering control

 * picture.* : add picture-id option. its a string that identifies the
               video.
 * mosaic.c : add mosaic-order option. its a comma separated list of
              picture-ids. Any picture who's id isn't found in the list
              will be placed after skiping the necessary number of
              slots needed to place all pictures defined in this list.

  (fixes WMA decoding in BeOS nightly builds)

- fix IPv6 multicast address range
- more strict IPv4 multicast address range

  holding p_picture_vout->lock for too long.

  (what the hell is i_duplicate ?)

* modules/audio_filter/converter/s16tofloat32*, modules/audio_filter/format.c: s24l/s24b conversion routines.

dynamic, per-subpicture, font size control -- i_font_size added to subpicture_region_t, new marq-size and time-size shortcuts, accessible from rc

Remove extra SAP debug

* simplified the lirc code to listen for key-* strings which we can directly use to trigger hotkeys.
* updated the example.lircrc with new required strings
* added a notice to NEWS about changed lirc syntax.

* modules/control/Modules.am, rtci.c: really delete rtci.c and removed DOS CR/LF from the last commit.

                            parameters on the fly
 * mosaic.c : center image in rectangle when keep aspect ratio is enabled
 * picture.c : remove debug message

* removed prefs_widgets.h, prefs_widgets.m, playlistinfo.h, playlistinfo.m, equalizer.m, equalizer.h, voutgl.m, voutqt.m from the build target, so they don't get copied in the Resources-folder of the binary bundle

freetype and rc extensions.  i_font_color and i_font_opacity added to subpictures, allowing per-object control (defaulting to freetype).  marq and time updated to allow font color and opacity control.  rc update to allow OTF control of all marq and time options.

Some details:

* This was mostly taken verbatim from revision:5717 (before the vout
  Mozilla support was removed), though it's been edited pretty thoroughly,
  and is now much more commented.

* The "normal" vout display should be completely unaffected, since the
  plugin-relevant code paths are only taken when p_vout->p_sys->b_embedded is
  set to VLC_TRUE.  (I've tested the normal VLC.app, and it seems fine.)

* There are still some problems with the plugin when the Mozilla window is
  resized a lot.  I suspect this is due to threading issues with
  QuickDraw, but I don't know enough about QuickDraw to be sure.  Help
  with this would be very welcome.

* The original patch in revision:5717 optimised the plugin display
  slightly, by using a mask (clipping region) so that QuickDraw only
  updated the plugin's area of the dirty region.  I elected not to use
  a mask, since I thought the extra code complexity (i.e. lots more if()
  branches) isn't worth the incremental speedup.  (If, in fact, there was
  a speedup at all -- the extra overhead induced by calculating the
  intersection of the dirty region with the mask may have offset any
  benefits: only benchmarks will tell ...)

* Announce content-length
* Allow  boundary string customization
