Subject: kernel/panic.c: add missing \n

When a system panics, the "Rebooting in X seconds.." message is never
printed because it lacks a new line.  Fix it.

Subject: printk: rename nmi.c and exported api

A preparation patch for printk_safe work. No functional change.
- rename nmi.c to print_safe.c
- add `printk_safe' prefix to some (which used both by printk-safe
  and printk-nmi) of the exported functions.

Subject: sparc64: Send break twice from console to return to boot prom

Now we can also jump to boot prom from sunhv console by sending
break twice on console for both running and panicked kernel
cases.

Subject: sched/headers: Prepare for new header dependencies before moving code
 to <linux/sched/debug.h>

We are going to split <linux/sched/debug.h> out of <linux/sched.h>, which
will have to be picked up from other headers and a couple of .c files.

Create a trivial placeholder <linux/sched/debug.h> file that just
maps to <linux/sched.h> to make this patch obviously correct and
bisectable.

Include the new header in the files that are going to need it.
