ssl & orber: Remove ssl:pid/1 (has been pointless since R14)
stdlib: Updated otp_internal to reflect removal of deprecated function

Note the comment in this file incorrectly stated that ssl:pid/1 should be
removed in R17, the intention has always been R16. This function
has never done anything relevant for the new ssl implementation that is
default in R14 and the only available one in R15.
