Handle calloc(0,x) where different from malloc.

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.
