Add tracefs_function_notrace() to set the functions not to trace.
Create a per instance pthread mutex lock.

Changes since v1:

 - Close the file descriptors on freeing of the instance
 - Close the file descriptors on exec.


Steven Rostedt (VMware) (5):
  libtracefs: Close filter file descriptor on freeing of instance
  libtracefs: Close the filter file descriptor on exec()
  libtracefs: Move most functionality into helper function for
    tracefs_function_filter()
  libtracefs: Add tracefs_function_notrace() API
  libtracefs: Add a pthread_mutex per instance
