man: harmonize the various formulations in the HISTORY sections

While stereotyped repetitions are frowned upon in literature, they
serve a useful purpose in manual pages, because it is easier for
the user to find certain information if it is always presented in

It also attempts to make the pod files more grep friendly by

Make EVP_PKEY_asn1_add0() stricter about its input

It turns out that the strictness that was implemented in
EVP_PKEY_asn1_new() (see Github openssl/openssl#6880) was badly placed
for some usages, and that it's better to do this check only when the
method is getting registered.
