[v3,0/5] libtraceevent: Copy parsing functions from trace-cmd

Currently, trace-cmd does the work of parsing kallsyms, saved_cmdlines,
and printk_formats and feeding it to the libtraceevent tep handle. When
starting to write code snippets that work directly with libtracefs and
libtraceevent, I found that I need this functionality as well. But this
code doesn't need libtracecmd. As these files exist in /proc and in the
tracefs directly, just like we have events and headers that get parsed
by libtraceevent, add this functionality directly to libtraceevent, as
libtraceevent is made to parse files for processing of events, and all
of the above do exactly that.

Changes since version 2:

  Right after sending v1, I found that patch 2 had a small bug on
  install the documentation. Resending the whole series with the fix
  so that patchwork picks it up correctly.
