introduce dbg_printf_pevent_info() function
Introduce dbg_printf_pevent_info() for event debugging simplification.
Events are printed to STDERR, one event per line.
(pevent trace_seq_do_printf() uses STDOUT, making it difficult to read through
mixed powertop and trace_seq outputs).
$ powertop 2>events
$ less events
