Created the file tools/testing/ftrace/test.d/functions that will
hold helper functions.
Current helper functions include:
Add clear_trace() helper to reset the trace file
Used as a descriptive name to show that "echo > trace" is clearing
the trace file.
Add disable/enable_tracing() helper calls
Add calls that disable and enable tracing respectively by echoing
0 or 1 into tracing_on.
Add helper reset_tracer() function
Add a helper function reset_tracer() that will clear the current_tracer
(echo nop > current_tracer).
