[PATCH] Export all functions in lib/string.c

Quite a few functions in lib/string.c are not exported.  I ran into this
trying to use strnchr() in a module.

This patch
 - exports every function defined in lib/string.c
 - adds some missing __HAVE_ARCH_xxx defines for i386
 - gets rid of the exports of functions from lib/string.c in arch/s390
   (BTW, why is s390 exporting things NOVERS?)
