[0/4] kernel-shark: Add sched_waking event for sched plugin processing

Hi Yordan,

I was using kernel shark to examine vsock events, and noticed that when I
only enabled sched_waking events, it did not give me the wake up boxes in
the task plots. I decided to look at the code and modify it to handle it.

When doing that, I noticed that the "success" field of the event was being
used. This is an obsolete field that will hopefully someday be removed. So I
added a patch to remove that. I also did not want to just add cut and paste
code to add the sched_waking, and instead made helper functions to process
the events all the same. And finally, I added the sched_waking code.

Can you review these patches and if they are fine by you, give your
"Reviewed-by" tag. Otherwise let me know if there's an issue that I should
fix.

Thanks!
