Subject: [PATCH 09/13] Move bp_type_idx to kernel/event/hw_breakpoint.c

This has a "#ifdef CONFIG_*" that used to be exposed to userspace.

The names in here are so generic that I don't think it's a good idea
to expose them to userspace (or even the rest of the kernel).  Since
there's only one kernel user, it's been moved to that file.
