[PATCH 20/47] libtraceevent: Remove tep_register_trace_clock()

[Arnaldo Carvalho de Melo]

From: Tzvetomir Stoyanov <tstoyanov@xxxxxxxxxx>

The tep_register_trace_clock() API is used to instruct the traceevent
library how to print the event time stamps. As event print interface if
redesigned, this API is not needed any more.  The new event print API is
flexible and the user can specify how the time stamps are printed.
