Subject: [PATCH 03/43] sched: Clean up and standardize #if/#else/#endif markers in sched/core.c

 - Use the standard #ifdef marker format for larger blocks,
   where appropriate:

	#if CONFIG_FOO
	...
	#else /* !CONFIG_FOO: */
	...
	#endif /* !CONFIG_FOO */

 - Apply this simplification:

	-#if defined(CONFIG_FOO)
	+#ifdef CONFIG_FOO

 - Fix whitespace noise.

 - Use vertical alignment to better visualize nested #ifdef blocks,
   where appropriate:

	#ifdef CONFIG_FOO
	# ifdef CONFIG_BAR
	...
	# endif
	#endif
