[COMMITTED PATCH] Provide __libc_fatal for rtld.

This makes it possible to use __libc_fatal in rtld code.


	* include/stdio.h: Add rtld_hidden_proto (__libc_fatal).
	* elf/dl-minimal.c: For readability, reorder some definitions and
	introduce more page breaks.  Include <stdio.h>.
	(__libc_fatal): New function.
