tools lib traceevent: Add jbd2 plugin
Backporting jbd2 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 field resolving functions for following tracepoint
events:
jbd2:jbd2_checkpoint_stats
jbd2:jbd2_run_stats
The diff of 'perf script' output generated by old and new code:
(data was generated by 'perf record -e 'jbd2:jbd2_run_stats,jbd2:jbd2_checkpoint_stats' -a')
--- script.jbd2.old

This plugin also adds jbd2_dev_to_name function, which was removed from
jdb2 tracepoints recently. Keeping it in for backward compatibility
reasons.
