cosmetics: make some arguments const, "unsigned char"->uint8_t

Mark input-only buffers as const.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@32652 b3059339-0415-0410-9bf9-f77b7e298cf2

Use uint8_t type instead of unsigned char.

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@32653 b3059339-0415-0410-9bf9-f77b7e298cf2

Mark input buffer that is never modified as const.
