v2 -> v3 :
* move the check for missing changes to MAINTAINERS and trace-events
later on, as otherwise the check for in_commit_log will not be done
on an up to date value, causing fromfile and realfile to not be set,
and matching unwanted strings inside the commit log.
* Ensure that at least one file name is passed to grep.
----
v1 -> v2 :
* track the "from" file in addition to the "to" file,
and grep into both (if they exist), looking for trace.h, trace-root.h
If files are reachable and readable, emit a warning if there is no
update to trace-events.

This patch still has an RFC tag. Is it ready to be merged? Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com>

I found some issues with it, with false negatives, that I still do not understand. If anybody wants to rework this taking this as starting point, that's good, otherwise I will get back to it when I can.. I am not sure about the "move the check" part in v2 -> v3, and if anybody has more input and can help to understand this aspect, welcome to collaborate on this. Ciao, CLaudio
