       Callback Functions.

       Functions that plug into various plug points in the OpenSSL path validation mechanism. These functions
       add CRL checking, X509 Extension handling and proxy validation.

intglobus_gsi_callback_check_issued(X509_STORE_CTX*context,X509*cert,X509*issuer)
       OpenSSL X509_check_issued() wrapper. This function wraps the OpenSSL X509_check_issued() call and catches
       the error caused by the fact that a proxy certificate issuer may not have to have the correct KeyUsage
       fields set.

       Parameterscontext The validation state object.
           cert The certificate to check
           issuer The issuer certificate to check

       Returns
           1 on success 0 on failure

   intglobus_gsi_callback_create_proxy_callback(intpreverify_ok,X509_STORE_CTX*x509_context)
       Independent path validation callback. This function provides a path validation callback for validation
       outside of a SSL session. It should be used in X509_STORE_set_verify_cb_func().

       Parameterspreverify_ok Communicates the result of default validation steps performed by OpenSSL

           x509_context The validation state object

       Returns
           1 on success 0 on failure

   globus_result_tglobus_gsi_callback_get_SSL_callback_data_index(int*index)
       Get callback data index from SSL structure. Retrieve or create the index for our callback data structure
       in the SSL structure.

       Parametersindex Will contain the index upon return

       Returns
           GLOBUS_SUCCESS unless an error occurred, in which case, a globus error object ID is returned

   globus_result_tglobus_gsi_callback_get_X509_STORE_callback_data_index(int*index)
       Get callback data index from X509_STORE. Retrieve or create the index for our callback data structure in
       the X509_STORE.

       Parametersindex Will contain the index upon return

       Returns
           GLOBUS_SUCCESS unless an error occurred, in which case, a globus error object ID is returned

   intglobus_gsi_callback_handshake_callback(intpreverify_ok,X509_STORE_CTX*x509_context)
       SSL path validation callback. This function provides a path validation callback for the validation part
       of establishing a SSL session. It handles proxy certificates, X509 Extensions and CRL checking. It should
       be used in SSL_CTX_set_verify().

       Parameterspreverify_ok Communicates the result of default validation steps performed by OpenSSL

           x509_context The validation state object.

       Returns
           1 on success 0 on failure

   intglobus_gsi_callback_X509_verify_cert(X509_STORE_CTX*context,void*arg)
       Certificate verify wrapper. This function wraps the OpenSSL certificate verification callback for the
       purpose of a replacing the standard issuer check with one that deals with proxy certificates. Should be
       used with SSL_CTX_set_cert_verify_callback()

       Parameterscontext The X509_STORE_CTX for which to register the callback.
           arg Arguments to the callback. Currently ignored.

       Returns
           1 on success 0 on failure
