    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.

    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.
