Update RSA EVP_PKEY_METHOD to use the OCTET STRING form of MDC2 signature:

signatures and MDC2 using EVP or RSA_sign. This has become more apparent
when the dgst utility in OpenSSL 1.0.0 and later switched to using the
EVP_DigestSign functions which call RSA_sign.

This means that the signature format OpenSSL 1.0.0 and later used with
dgst -sign and MDC2 is incompatible with previous versions.

Add detection in RSA_verify so either format works.

Note: MDC2 is disabled by default in OpenSSL and very rarely used in practice.

Before this the only way to add a custom chain was in the parent SSL_CTX
(which is shared by all key types and SSL structures) or rely on auto
chain building (which is performed on each handshake) from the trust store.

Thanks to Antonio Martin, Enterprise Secure Access Research and
Development, Cisco Systems, Inc. for discovering this bug and
preparing a fix. (CVE-2012-0050)

The cipher definitions of these ciphersuites have been around since SSLeay
but were always disabled. Now OpenSSL supports DH certificates they can be
finally enabled.

Various additional changes were needed to make them work properly: many
unused fixed DH sections of code were untested.

(While the 1.0.0f CHANGES entry on VOS PRNG seeding was missing
in HEAD, the actual code is here already.)
