tools tools, tools lib traceevent: Make traceevent APIs more consistent

Browse source 
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.
