[PATCH 3/6] tools/lib/traceevent: Man pages fix, changes in event printing APIs

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>

APIs for printing various trace event information were redesigned to
be more simple. However, the main libtraceevent man page was not updated
with those changes. The documentation is updated to describe the new
event print API.
