   @brief Masking the password if it is passed as command line argument.

   @details It works in Linux and changes cmdline in ps and /proc/pid/cmdline,
            but it won't work for history file of shell.
            The command line arguments are copied to another array and the
            password in the argv is masked. This function is called just after
            "handle_options" because in "handle_options", the agrv pointers
            are altered which makes freeing of dynamically allocated memory
            difficult. The password masking is done before all other operations
            in order to minimise the time frame of password visibility via cmdline.
