Subject: [PATCH 06/15] tools/lib/traceevent, tools/perf: Add prefix tep_ to all print_*
 structures

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

In order to make libtraceevent into a proper library, variables, data
structures and functions require a unique prefix to prevent name space
conflicts. That prefix will be "tep_". This adds prefix tep_ to all
print_* structures
