This change resolves a number of problems and obviates multiple kludges.
A new feature is that you can now say "AES256" or "AES128" (not just
"AES", which enables both).

In some cases the ciphersuite list generated from a given string is
affected by this change.  I hope this is just in those cases where the
previous behaviour did not make sense.

questions now is the OpenSSL core team under openssl-core@openssl.org.  And
add a paragraph about the dual-license situation to make sure people recognize
that _BOTH_ the OpenSSL license _AND_ the SSLeay license apply to the OpenSSL
toolkit.
