74096890ba Initial "opaque SSL" framework. If an application defines OPENSSL_NO_SSL_INTERN 
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.

0e1dba934f 1. Changes for s_client.c to make it return non-zero exit code in case 
of handshake failure

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

0a05123a6c Include "!eNULL" in SSL_DEFAULT_CIPHER_LIST to make sure that a 
ciphersuite string such as "DEFAULT:RSA" cannot enable
authentication-only ciphersuites.

Also, change ssl_create_cipher_list() so that it no longer
starts with an arbitrary ciphersuite ordering, but instead
uses the logic that we previously had in SSL_DEFEAULT_CIPHER_LIST.
SSL_DEFAULT_CIPHER_LIST simplifies into just "ALL:!aNULL:!eNULL".

52b8dad8ec Reorganize the data used for SSL ciphersuite pattern matching. 
This change resolves a number of problems and obviates multiple kludges.
A new feature is that you can now say "AES256" or "AES128" (not just
"AES", which enables both).

In some cases the ciphersuite list generated from a given string is
affected by this change.  I hope this is just in those cases where the
previous behaviour did not make sense.
