[PATCH 19/27] tools lib traceevent: Rename data2host*() APIs

[Arnaldo Carvalho de Melo]

From: "Tzvetomir Stoyanov (VMware)" <tz.stoyanov@xxxxxxxxx>

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 renames data2host*() APIs
