tv.h: Change function pointer types to proper declarations

git-svn-id: svn://svn.mplayerhq.hu/mplayer/trunk@31388 b3059339-0415-0410-9bf9-f77b7e298cf2

Note that the code is still questionable after this commit - the
shared data structure has pointers to "struct priv", but different
files use different incompatible definitions for that struct.
