Add support for ECDH in enveloped data. The CMS ctrls for the EC ASN1
method decode/encode the appropriate parameters from the CMS ASN1 data
and send appropriate data to the EC public key method.
(cherry picked from commit 88e20b85)

Add X9.62 KDF to EC EVP_PKEY_METHOD.
(cherry picked from commit 25af7a5d)

Add hooks to support key agreement recipient info type (KARI) using
algorithm specific code in the relevant public key ASN1 method.
(cherry picked from commit 17c2764d)

Add new tests to cms-test.pl covering PSS and OAEP.
(cherry picked from commit 32b18e03)

Add support for custom public key parameters in the cms utility using
the -keyopt switch. Works for -sign and also -encrypt if -recip is used.
(cherry picked from commit 02498cc8)

Document use of -keyopt to use RSA-PSS and RSA-OAEP modes.
(cherry picked from commit 4bf4a650)

Extend RSA ASN1 method to support CMS PSS signatures for both sign
and verify.

For signing the EVP_PKEY_CTX parameters are read and the appropriate
CMS structures set up.

For verification the CMS structures are analysed and the corresponding
parameters in the EVP_PKEY_CTX set.

Also add RSA-OAEP support.

For encrypt the EVP_PKEY_CTX parameters are used.

For decrypt the CMS structure is uses to set the appropriate EVP_PKEY_CTX
parameters.
(cherry picked from commit 0574cadf)

Also sync error codes with OpenSSL 1.0.1 and add new ones.

Add OAEP ctrls to retrieve MD and label. Return errors if
an attempt is made to set or retrieve OAEP parameters when
padding mode is not OAEP.
(cherry picked from commit 211a14f6)

Extend OAEP support. Generalise the OAEP padding functions to support
arbitrary digests. Extend EVP_PKEY RSA method to handle the new OAEP
padding functions and add ctrls to set the additional parameters.

Add some RSA error codes used by the FIPS module.

(cherry picked from commit e0f7cfda)

Add support for customisation of CMS handling of signed and enveloped
data from custom public key parameters.

This will provide support for RSA-PSS and RSA-OAEP but could also be
applied to other algorithms.
(cherry picked from commit e365352d)

Add OIDs for KDF schemes from RFC5753 and add cross references for
each type and the appropriate digest to use.

Backport support for FIPS 186-2 DSA parameter generation from
HEAD. Redirect to FIPS in FIPS mode and workaround prototype error.

Add support for DH parameter generation using DSA methods including
FIPS 186-3.

Add code to support GCM an CCM modes in evp_test. On encrypt this
will compare the expected ciphertext and tag. On decrypt it will
compare the expected plaintext: tag comparison is done internally.

Add a simple CCM test case and convert all tests from crypto/modes/gcm128.c

is not used by default.

Make DTLS behave like TLS when negotiating version: record layer has
DTLS 1.0, message version is 1.2.

Tolerate different version numbers if version hasn't been negotiated
yet.
(cherry picked from commit 40088d8b)

Add DTLS record header parsing, different client hello format and add
HelloVerifyRequest message type.

Add code to d1_pkt.c to send message headers to the message callback.

Check for Suite B support using method flags instead of version numbers:
anything supporting TLS 1.2 cipher suites will also support Suite B.

Return an error if an attempt to use DTLS 1.0 is made in Suite B mode.

If we successfully match a cookie don't set return value to 2 as this
results in other error conditions returning 2 as well.

Instead set return value to -2 which can be checked later if everything
else is OK.
