Restore the old behaviour: - preferences must be read-write for tv_preferences.c , read-only for all other modules -> use pointer to const struct - init functions must get the plugin buffer + its size as arguments for easily adding new functions -> use pointer to buffer pointer and size to make allocation easier - preferences meaning is private to each file and must not be known by tv_preferences.c -> move tv_check_header_and_footer() back in tv_window.c; also avoid chaining 3 times the callbacks by calling tv_set_preferences() only once if more than one preference needs changing git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27089 a1c6a512-1295-4272-9138-f99709370657
