tools lib traceevent: Add function plugin
Backporting function plugin.
Backported from Steven Rostedt's trace-cmd repo (HEAD 0f2c2fb):
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
This plugin adds function and parent function fields resolving for
ftrace:function tracepoint event.
The diff of 'perf script' output generated by old and new code:
(data was generated by 'perf record -e ftrace:function ls')
--- script.function.old
+++ script.function.new

Removing options support as it's not backported yet.
Currently this plugin supports 2 options:
'parent' to display parent function
'indent' to show function call indents
Enabling both of them by default.
