api gives proper detection for too small buffer. Thanks to Ross for pointing
this out.

* modules/stream_out/transcode.c: small cleanup + added an fps (to specify the output frame rate) and an audio-sync option (to add/drop video frames to keep a constant framerate while being synchronised on the audio track).

fewer garbled frames. Still not perfect though.

    When the buffer passed to live.com don't have space for another packet 
    when we get it back we assume that the stream uses larger frames than
    our current buffer and we increase the buffer.

* modules/mux/asf.c: the asf muxer can only add streams on the fly when in http mode (otherwise this will screw up the header re-writing on Close().)

 + gui/beos/*: got rid of the VlcWrapper thing which is unneccessaraly
               complex now that we have variables

 Language/subtitle selection works again in the BeOS UI, but there's
 still a lot to fix :|

 + macosx/vout*: --macosx-vout and --macosx-opengl-effect
                 no longer exist

  + vout.m contains the common code for the QT video output and the
    GL provider (window creation, events handling)
  + opengl.c: higher priority on OS X
 Things are a bit broken atm, any help to debug is welcome ;p

 There's a new stable gcc out for BeOS, now we can re-enable 3DNow/SEE
 and build matroska support

    + Build memcpyaltivec and deinterlace with -maltivec.
    + Check for -ldts_pic before -ldts.

    + Don't manage this patch with dpatch since it causes ownership issues.
  * debian/control:
    + Added a missing dpatch build dependency (Closes: #263363).
    + Removed the modplug plugin until libmodplug-dev enters Debian.

* fixed a line ending replace problem with subviewer subs
* single char subtitle lines should now work subviewer and subrip

* modules/stream_out/transcode.c: support for subtitles transcoding.
* modules/codec/dvbsub.c: DVB subtitles encoder (developed for Anevia, www.anevia.com).
  + only works on YUVP subpictures for now.
  + not completely spec compliant yet.

* src/video_output/vout_subpictures.c: fixed a deadlock that happened when 2 ephemer subpictures had the same date.

intf: Equalizer window in window menu
equalizer.m: presets should work now
equalizer.c, Modules.am, equalizer_presets.h: presets are stored in a separate file
