stralloc_cats - append data to a stralloc

       stralloc_cats  appends  a \0-terminated string from buf to the end of the string stored in sa, allocating
       space if necessary, and returns 1. If sa is unallocated, stralloc_cats is the same as stralloc_copys.  If
       it runs out of memory, stralloc_cats leaves sa alone and returns 0.
