Subject: [PATCH v3 1/1] kernel.h: Split out panic and oops helpers
kernel.h is being used as a dump for all kinds of stuff for a long time.
Here is the attempt to start cleaning it up by splitting out panic and
oops helpers.
There are several purposes of doing this:
- dropping dependency in bug.h
- dropping a loop by moving out panic_notifier.h
- unload kernel.h from something which has its own domain
At the same time convert users tree-wide to use new headers, although
for the time being include new header back to kernel.h to avoid twisted
indirected includes for existing users.

v3: rebased on top of v5.13-rc1, collected a few more tags
Note WRT Andrew's SoB tag above: I have added it since part of the cases
I took from him. Andrew, feel free to amend or tell me how you want me
to do.
