	Configure assumes that if malloc(0) returns null then calloc(0,n) also does. On some old platforms (SunOS4) malloc behaves as expected (as determined by AC_FUNC_MALLOC) but calloc doesn't. Test for this at configure time and activate the replacement function if found, plus handle this case in rpl_calloc.

	On some platforms (AIX, maybe others) allocating zero bytes of memory via the various *alloc functions returns NULL, which is permitted by the standards. Autoconf has some macros for detecting this (with the exception of calloc for some reason) so use these and if necessary activate shims for them. ok djm@
