Currently the tracing dump_on_oops feature is implemented through
separate notifiers, one for die/oops and the other for panic;
given they have the same functionality, let's unify them.

Also improve the function comment and change the priority of the
notifier to make it execute earlier, avoiding showing useless trace
data (like the callback names for the other notifiers); finally,
we also removed an unnecessary header inclusion.

V3:
- Removed goto usage, as per Steven suggestion (thanks!).

V2:
- Different approach; instead of using IDs to distinguish die and
panic events, rely on address comparison like other notifiers do
and as per Petr's suggestion;

- Removed ACK from Steven since the code changed.
Hi Steven, apologies for the re-ping. Is there anything else to do in
this one, or do you think it's good enough?

Thanks,


Guilherme
