The Makefiles call the respective interpreter explicitly, but this makes
it easier to use the scripts manually.

This patch converts the existing power tracer into an event tracer,
so that power events (C states and frequency changes) can be
tracked via "perf".
This also removes the perl script that was used to demo the tracer;
its functionality is being replaced entirely with timechart.

Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/"
directory name to mount debugfs filesystem for ftrace according to
./Documentation/tracers/ftrace.txt file.
And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is
existed in kernel source like ftrace, DRM, Wireless, Documentation,
Network[sky2]files to mount debugfs filesystem.
debugfs means debug filesystem for debugging easy to use by greg kroah
hartman. "/sys/kernel/debug/" name is suitable as directory name
of debugfs filesystem.

Fix inconsistency of directory name to mount debugfs filesystem.

This script parses a function trace and then produces a hierarchical
view of the function call stack after processing it into a tree.
Changes on V2 thanks to the trace sent by Steven:
- Support both the files "trace" and "trace_pipe" (comments and space
differences)
- Correct the mini HOW-TO at the beginning.
