Steven Rostedt df4fc31558 ftrace: add function tracing to single thread 
Impact: feature to function trace a single thread

This patch adds the ability to function trace a single thread.
The file:

  /debugfs/tracing/set_ftrace_pid

contains the pid to trace. Valid pids are any positive integer.
Writing any negative number to this file will disable the pid
tracing and the function tracer will go back to tracing all of
threads.

This feature works with both static and dynamic function tracing.
