Change ssl_create_cipher_list() to prefer ephemeral ECDH over
ephemeral DH.

ciphersuite string such as "DEFAULT:RSA" cannot enable
authentication-only ciphersuites.

Also, change ssl_create_cipher_list() so that it no longer
starts with an arbitrary ciphersuite ordering, but instead
uses the logic that we previously had in SSL_DEFEAULT_CIPHER_LIST.
SSL_DEFAULT_CIPHER_LIST simplifies into just "ALL:!aNULL:!eNULL".

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.
