Currently we don't have a way to check if there are dumpers set,
except counting the list members maybe. This patch introduces a very
simple helper to provide this information, by just keeping track of
registered/unregistered kmsg dumpers. It's going to be used on the
panic path in the subsequent patch.

FYI, it is considered "bad form" to reference in the change log "this
patch". We know this is a patch. The change log should just talk about what
is being done. So can you reword your change logs (you do this is almost
every patch). Here's what I would reword the above to be:

Thanks for the hint, you're right - it's almost in all of my patches.
I'll reword all of them (except the ones already merged) to remove this
"bad form".

Cheers,
