Subject: [PATCH 7/7] docgen,stdlib: Fix dialyzer warning issues with
 otp_internal

What otp_internal returns changes depending on which functions/types
are deprecated/removed. So in order to cover all cases we need to take
care of more than what is returned. Dialyzer does not seem to like this
so we silence it with an apply/3.
