releasenotes: extract helper for checking for incompatible arguments
This patch extracts a new check_incompatible_arguments() function
similar to check_at_most_one_arg(). The difference is that the new
function is for checking for arguments that are disallowed together
with some other argument but not mutually exclusive among themselves.
