        ** This is no guarantee of security, but its just a helper to
        prevent old memory accidentally being included/used elsewhere.

        * camel-smime-context.c (sm_decrypt): mark the output stream
        'secure'.

        * camel-gpg-context.c (gpg_decrypt): set the output stream to
        secured, so we automagically blank it out on finalise.

        * camel-stream-mem.c (camel_stream_mem_set_secure): set the
        memory-stream 'secured', all we do at the moment is blank out the
        buffer on finalise.
        (camel_stream_mem_set_byte_array, camel_stream_mem_finalize):
        clear memory if owner and secured.  kill dead comment.
        (clear_mem): utilitiy to set memory to 0xABADF00D

        ** See bug #61186.

        * camel-cipher-context.c (camel_cipher_sign):
        (camel_cipher_verify, camel_cipher_encrypt, camel_cipher_decrypt):
        Add preliminary progress reporting.
