7c770d572a Add and use a constant-time memcmp.
This change adds CRYPTO_memcmp, which compares two vectors of bytes in
an amount of time that's independent of their contents. It also changes
several MAC compares in the code to use this over the standard memcmp,
which may leak information about the size of a matching prefix.

5863163732 Additional compatibility fix for MDC2 signature format.
Update RSA EVP_PKEY_METHOD to use the OCTET STRING form of MDC2 signature:
this will make all versions of MDC2 signature equivalent.

83cb7c4635 An incompatibility has always existed between the format used for RSA
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.

fa1ba589f3 Add algorithm specific signature printing. An individual ASN1 method can
now print out signatures instead of the standard hex dump.

More complex signatures (e.g. PSS) can print out more meaningful information.

Sample DSA version included that prints out the signature parameters r, s.

[Note EVP_PKEY_ASN1_METHOD is an application opaque structure so adding
 new fields in the middle has no compatibility issues]
