Move stdlib header files to include/lib/stdlib

* Move stdlib header files from include/stdlib to include/lib/stdlib for
  consistency with other library headers.
* Fix checkpatch paths to continue excluding stdlib files.
* Create stdlib.mk to define the stdlib source files and include directories.
* Include stdlib.mk from the top level Makefile.
* Update stdlib header path in the fip_create Makefile.
* Update porting-guide.md with the new paths.

- * rune_t is declared to be an ``int'' instead of the more natural

- * ints cannot hold 32 bits, you will be in trouble.  The reason an int was
- * chosen over a long is that the is*() and to*() routines take ints (says
- * ANSI C), but they use __ct_rune_t instead of int.
- *
- * NOTE: rune_t is not covered by ANSI nor other standards, and should not
- * be instantiated outside of lib/libc/locale.  Use wchar_t.  wchar_t and
- * rune_t must be the same type.  Also, wint_t must be no narrower than
- * wchar_t, and should be able to hold all members of the largest
- * character set plus one extra value (WEOF), and must be at least 16 bits.

- *	* Other than that, if you don't know the likelihood of a test
- *	  succeeding from empirical or other `hard' evidence, don't
- *	  make predictions.
- *
- *	* These are meant to be used in places that are run `a lot'.
- *	  It is wasteful to make predictions in code that is run
- *	  seldomly (e.g. at subsystem initialization time) as the
- *	  basic block reordering that this affects can often generate
