Actually indent_thread() is a very useful function, but

sometimes you're probing something that is not related to
any task, as an interrupt function, and if the application
changes during the interrupt, the indentation gets confused.
For example:

    0 swapper(0): -> neo_copy_data_from_queue_to_uart
    69 a.out(7659):   -> neo_parse_modem
    74 a.out(7659):    -> neo_param
    14 swapper(0): <- neo_copy_data_from_queue_to_uart
    83 a.out(7659):  -> jsm_carrier
    86 a.out(7659):  <- jsm_carrier
     0 swapper(0): -> neo_parse_modem
    94 a.out(7659): <- jsm_tty_set_termios
     8 swapper(0): <- neo_parse_modem

So, I decided to create a simpler function that doesn't
consider the task.

Much of the idea of this implementation came from Frank(Thanks)
