Remove autoconf things and OS header stuff (namely NULL) from gansidecl.h:

        * gansidecl.h (ATTRIBUTE_UNUSED): Use __unused__ not `unused'.
        Don't define NULL here.  Also, remove all vestiges of autoconf
        based checks for bcmp/bcopy/bzero/index/rindex.
        * system.h: Immediately after including stdio.h, check for and if
        necessary provide a default definition of NULL.
