Subject: [PATCH 23/35] tools lib traceevent: Rename internal parser related APIs
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_" and not "pevent_". This changes
APIs: pevent_buffer_init, pevent_read_token, pevent_free_token,
pevent_peek_char, pevent_get_input_buf, pevent_get_input_buf_ptr
