Initial incomplete TLS v1.2 support. New ciphersuites added, new version

checking added, SHA256 PRF support added.

At present only RSA key exchange ciphersuites work with TLS v1.2 as the
new signature format is not yet implemented.

  Changes between 1.0.1 and 1.1.0  [xx XXX xxxx]
 
+  *) Initial TLS v1.2 support. Add new SHA256 digest to ssl code, switch
+     to SHA256 for PRF when using TLS v1.2 and later. Add new SHA256 based
+     ciphersuites. At present only RSA key exchange ciphersuites work with
+     TLS v1.2. Add new option for TLS v1.2 replacing the old and obsolete
+     SSL_OP_PKCS1_CHECK flags with SSL_OP_NO_TLSv1_2. New TLSv1.2 methods
+     and version checking.
+     [Steve Henson]
+
   *) New option OPENSSL_NO_SSL_INTERN. If an application can be compiled
      with this defined it will not be affected by any changes to ssl internal
      structures. Add several utility functions to allow openssl application
