  Modified files:
    lib/libstand         Makefile stand.h zalloc_defs.h 
                         zalloc_malloc.c 
  Added files:
    lib/libstand         zutil.h.diff 
  Log:
  Reimplement malloc/free debugging that includes the offending file:line
  info.  This turned out to be rather useful on ia64 for tracking down
  malloc/free problems.
  Detect duplicate free()'s - otherwise these show up as a guard1 failure
  and it looks like corruption instead of something simple like a second
  free() where there shouldn't be.
  Deal with libz using libc headers and not seeing the malloc/free stuff that
  we provide in libstand.  Do similar nastiness to what is done for bzlib.
  
  Tested on: i386, ia64 (compile, run)
