Subject: [PATCH 06/16] tools lib traceevent: Initialize host_bigendian at tep_handle allocation

From: Tzvetomir Stoyanov <tstoyanov@...are.com>

This patch initializes the host_bigendian member of the tep_handle
structure with the byte order of the current host, when this handler is
created - in tep_alloc() API. We need this in order to remove the
tep_set_host_bigendian() API.
