Makefile.am: try it the simple way now, trusting the user not to open another dmg with the same name

live-starttime.patch is merged upstream and bumping up livemedia's version number is no longer needed.

MacOSX/Framework/VLCEventManager.m: Don't send grouped events to the same target if there is an event in-between.

Qt4 - extended... attempt to fix extended panel size... The culprit is still the VideoFilter Widget.

video_output/opengllayer.m: Don't rely on CAOpenGLLayer when frames should be displayed. Display frame when vout tells us to do so.

MacOSX/Framework/VLCEventManager: Forgot in previous commit. Code clean up/documentation.  Standardized the way duplicate notifications are consolidated.

MacOSX/Framework/Examples/test: Don't waste time getting the length of the video while we're doing a drag & drop operation.

shouldn't break anything (tested on mp4/ts files, rtp stream and http/ts
stream). Files play correctly and MP4Box/ffmpeg recognize them

MacOSX/Framework: Remove all references to fullscreen mode, it should be the host application's responsibility to transition between fullscreen and window mode.

input/input.c: Define DEMUX_CAN_SEEK and correctly set "seekable" accordingly. (This could introduce regression such as seekable item no more seekable, but I should have greped enough...).

video_output/opengllayer.m: Hopefully fix the tearing issues by correctly updating textures, and using a nice trick to save the current opengl context. (Note, we can't draw to it directly).
