new style for debug information about functions: no more SETFUNCTION
...
opcodes. When a function is called, its entry in the stack is marked with
LUA_T_(C)MARK, so function 'luaD_stackedfunction' can find it if
needed.
Functions now have their file names in the headers, so there is no need
of 'addfile' and the like.
