deprecate palette8topacked32 in favor of public API functions sws_convertPalette8ToPacked32 and -24
additionallym deprecate palette8torgb16 and its bgr variant without replacement. These functions are not meant to be used by applications. Discussed at: http://comments.gmane.org/gmane.comp.video.ffmpeg.devel/109340 Originally committed as revision 31301 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale
