(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.

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.

Make DHparams_dup work properly with X9.42 DH parameters.

Add support for key wrap algorithms via EVP interface.

Generalise AES wrap algorithm and add to modes, making existing
AES wrap algorithm a special case.

Move test code to evptests.txt

(cherry picked from commit 282a480a)

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

Return an error if an attempt is made to enable the Dual EC DRBG: it
is not used by default.
(cherry picked from commit a4870de5)

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.
(cherry picked from commit 4544f0a6)

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.
(cherry picked from commit c56f5b8e)

Add new methods DTLS_*_method() which support both DTLS 1.0 and DTLS 1.2 and
pick the highest version the peer supports during negotiation.

As with SSL/TLS options can change this behaviour specifically
SSL_OP_NO_DTLSv1 and SSL_OP_NO_DTLSv1_2.

Port TLS 1.2 GCM code to DTLS. Enable use of TLS 1.2 only ciphers when in
DTLS 1.2 mode too.
(cherry picked from commit 4221c0dd)

The relaxed signing requirements for fixed DH certificates apply to DTLS 1.2
too.
(cherry picked from commit fbbaacca)

Add DTLS1.2 support for cached records when computing handshake macs
instead of the MD5+SHA1 case for DTLS < 1.2 (this is a port of the
equivalent TLS 1.2 code to DTLS).
(cherry picked from commit 04fac500)

Add correct flags for DTLS 1.2, update s_server and s_client to handle
DTLS 1.2 methods.

Currently no support for version negotiation: i.e. if client/server selects
DTLS 1.2 it is that or nothing.

Since this is always called from DTLS code it is safe to assume the header
length should be the DTLS value. This avoids the need to check the version
number and should work with any version of DTLS (not just 1.0).
(cherry picked from commit 9cf0f187)

Extend DTLS method creation macros to support version numbers and encryption
methods. Update existing code.
(cherry picked from commit cfd298b7)

Some TLS extensions were disabled for DTLS. Possibly because they caused
problems with the old duplicated code. Enable them again.
(cherry picked from commit 874a18cf)

Use the enc_flags field to determine whether we should use explicit IV,
signature algorithms or SHA256 default PRF instead of hard coding which
versions support each requirement.

(cherry picked from commit 6de2649a)

Revise DTLS code. There was a *lot* of code duplication in the
DTLS code that generates records. This makes it harder to maintain and
sometimes a TLS update is omitted by accident from the DTLS code.

Specifically almost all of the record generation functions have code like
this:

some_pointer = buffer + HANDSHAKE_HEADER_LENGTH;
... Record creation stuff ...
set_handshake_header(ssl, SSL_MT_SOMETHING, message_len);

...

write_handshake_message(ssl);

Where the "Record creation stuff" is identical between SSL/TLS and DTLS or
in some cases has very minor differences.

By adding a few fields to SSL3_ENC to include the header length, some flags
and function pointers for handshake header setting and handshake writing the
code can cope with both cases.
