Tzvetomir Stoyanov 6d2d6fd7e3 tools lib traceevent: Changed return logic of trace_seq_printf() and trace_seq_vprintf() APIs ...

In order to make libtraceevent into a proper library, its API should be
straightforward.

The trace_seq_printf() and trace_seq_vprintf() APIs have inconsistent
returned values with the other trace_seq_* APIs.

This path changes the return logic of trace_seq_printf() and
trace_seq_vprintf() to return the number of printed characters, as the
other trace_seq_* related APIs.
