Future versions of OpenSSL use the canonical terms "ECDHE" and "DHE"
as configuration strings and compilation constants. This patch
introduces aliases so that the stable 1.0.2 branch can be
forward-compatible with code and configuration scripts that use the
normalized terms, while avoiding changing any library output for
stable users.

In the ssl_cipher_get_evp() function, fix off-by-one errors in index validation before accessing arrays.
Bug discovered and fixed by Miod Vallat from the OpenBSD team.
PR#3375
SRP ciphersuites do not have no authentication. They have authentication
based on SRP. Add new SRP authentication flag and cipher string.

Although the memory allocated by compression methods is fixed and
cannot grow over time it can cause warnings in some leak checking
tools. The function SSL_COMP_free_compression_methods() will free
and zero the list of supported compression methods. This should
*only* be called in a single threaded context when an application
is shutting down to avoid interfering with existing contexts
attempting to look up compression methods.
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.

client hello message. Previously this could only be retrieved on an initial
connection and it was impossible to determine the cipher IDs of any uknown
ciphersuites.
(backport from HEAD)
all ssl related structures are opaque and internals cannot be directly
accessed. Many applications will need some modification to support this and
most likely some additional functions added to OpenSSL.
The advantage of this option is that any application supporting it will still
be binary compatible if SSL structures change.
(backport from HEAD).
Some #include statements were not properly protected. This will go unnoted
on most systems as openssl/comp.h tends to be installed as a system header
file by default but may become visible when cross compiling.

2. Changes to x509_certificate_type function (crypto/x509/x509type.c) to
make it recognize GOST certificates as EVP_PKT_SIGN|EVP_PKT_EXCH
(required for s3_srvr to accept GOST client certificates).
3. Changes to EVP
- adding of function EVP_PKEY_CTX_get0_peerkey
- Make function EVP_PKEY_derive_set_peerkey work for context with
ENCRYPT operation, because we use peerkey field in the context to
pass non-ephemeral secret key to GOST encrypt operation.
- added EVP_PKEY_CTRL_SET_IV control command. It is really
GOST-specific, but it is used in SSL code, so it has to go
in some header file, available during libssl compilation
4. Fix to HMAC to avoid call of OPENSSL_cleanse on undefined data
5. Include des.h if KSSL_DEBUG is defined into some libssl files, to
make debugging output which depends on constants defined there, work
and other KSSL_DEBUG output fixes
6. Declaration of real GOST ciphersuites, two authentication methods
SSL_aGOST94 and SSL_aGOST2001 and one key exchange method SSL_kGOST
7. Implementation of these methods.
8. Support for sending unsolicited serverhello extension if GOST
ciphersuite is selected. It is require for interoperability with
CryptoPro CSP 3.0 and 3.6 and controlled by
SSL_OP_CRYPTOPRO_TLSEXT_BUG constant.
This constant is added to SSL_OP_ALL, because it does nothing, if
non-GOST ciphersuite is selected, and all implementation of GOST
include compatibility with CryptoPro.
9. Support for CertificateVerify message without length field. It is
another CryptoPro bug, but support is made unconditional, because it
does no harm for draft-conforming implementation.
10. In tls1_mac extra copy of stream mac context is no more done.
When I've written currently commited code I haven't read
EVP_DigestSignFinal manual carefully enough and haven't noticed that
it does an internal digest ctx copying.
This implementation was tested against
1. CryptoPro CSP 3.6 client and server
2. Cryptopro CSP 3.0 server
