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_read_number, pevent_read_number_field
