      PXB-1626: Support encrypted redo and undo logs

      This patch adds support for encrypted redo and undo logs.

      Since redo and undo logs are just a special case of InnoDB
      tablespaces, changes needed to support them are minimal:

      • xtrabackup now recognises `--innodb_redo_log_encrypt' and
        `innodb_undo_log_encrypt' server variables. Values of these
        variables are saved to `backup-my.cnf' and used for prepare.
      • instead of using a keyring plugin for the case when
        `--transition-key' is specified, xtrabackup will look for
        encryption key in the `xtrabackup_keys' file.
      • since encrypted redo log is decrypted by `recv_read_log_seg',
        xtrabackup will encrypt it before writing to `xtrabackup_logfile'.
