printk: Make linux/printk.h self-contained
As it stands if you include printk.h by itself it will fail to compile because it requires definitions from ratelimit.h. However, simply including ratelimit.h from printk.h does not work due to inclusion loops involving sched.h and kernel.h. This patch solves this by moving bits from ratelimit.h into a new header file which can then be included by printk.h without any worries about header loops. The build bot then revealed some intriguing failures arising out of this patch. On s390 there is an inclusion loop with asm/bug.h and linux/kernel.h that triggers a compile failure, because kernel.h will cause asm-generic/bug.h to be included before s390's own asm/bug.h has finished processing. This has been fixed by not including kernel.h in arch/s390/include/asm/bug.h.
