Fix printing parameters of inlined functions.
* ada-lang.c (is_known_support_routine)
(ada_unhandled_exception_name_addr_from_raise): Provide NULL parameter
for find_frame_funname.
* python/py-frame.c (frapy_name): Likewise.
* stack.c (find_frame_funname): New parameter funcp.  Update the
function comment.  Fill it in.
(print_frame): New variable func.  Initialize it by
find_frame_funname.  Print arguments only if FUNC is not NULL.  Use
FUNC as the parameter of print_args_stub.
* stack.h (find_frame_funname): New parameter funcp.  Remove the
function declaration comment.
