Original commit message from CVS:
* plugins/elements/gsttee.c: (gst_tee_do_push),
(gst_tee_handle_buffer):
Always prefer an actual return value from a src
pad in place of NOT_LINKED. This means we return
WRONG_STATE when all src pads are WRONG_STATE
instead of NOT_LINKED.

Lock when replacing the last message to prevent
racing with the get_property method.

Add debug output
