In preparation for tracefs_sql(), the histogram logic needs some updates.
Restructure the API a little better. Since the API has not been part of a
tagged release, it is still allowed to change.

Add a way to show a partially created synthetic event, which can be used by
tracefs_sql() for creating histograms.

Changes since v1:

 - Fixed tracefs_synth_get_start_hist() when more than one key existed.

Steven Rostedt (VMware) (7):
  libtracefs: Change the tracefs_hist API to not take an instance
    immediately
  libtracefs: Expose tracefs_hist_command() as an API
  libtracefs: Add API tracefs_hist_append_filter()
  libtracefs: Add API tracefs_hist_show()
  libtracefs: Split up libtracefs-synth man page
  libtracefs: Add API tracefs_synth_get_start_hist()
  libtracefs: Add API tracefs_synth_complete()
