     [uidswap.c]
     change OpenSSH's xrealloc() function from being xrealloc(p, new_size)
     to xrealloc(p, new_nmemb, new_itemsize).

     realloc is particularly prone to integer overflows because it is
     almost always allocating "n * size" bytes, so this is a far safer
     API; ok deraadt@
