cleanup: vo_fbdev: simplify some code 

Simplify by using FFMAX3.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@33300 b3059339-0415-0410-9bf9-f77b7e298cf2

Simplify colormap generation code, avoid some mallocs and add frees
for one error case.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@33302 b3059339-0415-0410-9bf9-f77b7e298cf2

Use memcpy_pic instead of reimplementing it.
