The following changes since commit f17a60bac447adb35ebae1afeadc046abf80d780:

  cobalt/tracing: Primarily identify threads via pid (2017-10-01 11:33:58 +0200)

The xnftrace_printf patch has been proposed before, the others are new
and mostly deal with cleaning up and enhancing our tracepoints for ftrace.

I've also played with a patched trace-cmd/kernelshark that is now able
to detect Xenomai context switches and wakeups as well. It's a patch so
far, future versions of kernelshark are supposed to contain better
plugin interfaces to hook up more cleanly.
