tools tools, tools lib traceevent: Make traceevent APIs more consistent
Rename some traceevent APIs for consistency: tep_pid_is_registered() to tep_is_pid_registered() tep_file_bigendian() to tep_is_file_bigendian() to make the names and return values consistent with other tep_is_... APIs tep_data_lat_fmt() to tep_data_latency_format() to make the name more descriptive tep_host_bigendian() to tep_is_bigendian() tep_set_host_bigendian() to tep_set_local_bigendian() tep_is_host_bigendian() to tep_is_local_bigendian() "host" can be confused with VMs, and "local" is about the local machine. All tep_is_..._bigendian(struct tep_handle *tep) APIs return the saved data in the tep handle, while tep_is_bigendian() returns the running machine's endianness. All tep_is_... functions are modified to return bool value, instead of int.
