Deduplicate the mp_image planes allocation code.
The code in vf.c and mp_image.c is almost the same, though the one in vf.c is more up-to-date/has more bug fixes and thus is used as the basis (which is why the diff is so big). git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@30154 b3059339-0415-0410-9bf9-f77b7e298cf2
