List of new things:

- Add option "--raw-ip", to print raw ip instead of symbols.

- Sort the output by fragmentation by default, and support
multi keys.

- Collect and show cross node allocation stats.

- Collect and show alloc/free ping-pong stats.

- And help file.

Pekka, do you think we can remove kmemtrace now?

With kmem trace events, low-level analyzing can be done using
ftrace, and high-level analyzing can be done using perf-kmem.

And chance is, more people may use and improve perf-kmem, and it
will be well-maintained within the perf infrastructure. On the
other hand, I guess few people use and contribute to kmemtrace-user.

BTW, seems kmemtrace-user doesn't work with ftrace. I got setfault:

# ./kmemtraced
