[PATCH 13/14] tools/lib/traceevent: Add prefix tep_ to enum filter_trivial_type and all its members. Rename data2host*() APIs

["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_". This adds prefix tep_ to
enum filter_trivial_type and all its members, and renames data2host*() APIs
