     [xmalloc.c xmalloc.h]
     introduce xcalloc() and xasprintf() failure-checked allocations
     functions and use them throughout openssh

     xcalloc is particularly important because malloc(nmemb * size) is a
     dangerous idiom (subject to integer overflow) and it is time for it
     to die
