Subject[RFC][PATCH 07/24] tools/lib/traceevent, tools/perf: Rename pevent print APIs
From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.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_" and not "pevent_". This changes
APIs: pevent_print_field, pevent_print_fields, pevent_print_funcs,
pevent_print_printk
