Update to 1.76
    
    - New upstream release 1.76
      - Compatibility with OpenSSL 1.1, tested with openssl-1.1.0-pre5:
        - Conditionally remove threading locking code, not needed in 1.1
        - Rewrite code that accesses inside X509_ATTRIBUTE struct
        - SSL_CTX_need_tmp_RSA, SSL_CTX_set_tmp_rsa, SSL_CTX_set_tmp_rsa_callback,
          SSL_set_tmp_rsa_callback support not available in 1.1
        - SSL_session_reused is now native
        - SSL_get_keyblock_size modifed to use new API
        - OCSP functions modified to use new API under 1.1
        - SSL_set_state removed with 1.1
        - SSL_get_state and SSL_state are now equivalent and available in all
          versions
        - SSL_CTX_v2_new removed
        - SESSION_set_master_key removed with 1.1; code that previously used
          SESSION_set_master_key must now set $secret in the session_secret
          callback set with SSL_set_session_secret_cb
        - With 1.1, $secret in the session_secret callback set with
          SSL_set_session_secret_cb can be changed to alter the master key
          (required by EAP-FAST)
      - Added a function EC_KEY_generate_key similar to RSA_generate_key and a
        function EVP_PKEY_assign_EC_KEY similar to EVP_PKEY_assign_RSA; using
        these functions it is easy to create and use EC keys in the same way as RSA
        keys
      - Testing with LibreSSL 2.4.1
      - Provide support for cross context (and cross process) session sharing using
        the stateless TLS session tickets
      - Added documentation about downloading latest version from SVN
      - Added missing Module/install files to SVN
