stralloc_copy - copy data into a stralloc

       stralloc_copy  copies  the  string  stored  in  safrom  into  sa. It is the same as stralloc_copyb(&sato,
       safrom.s, safrom.len).  safrom must already be allocated.

       The data that sa previously contained is overwritten and truncated.

       If stralloc_copy has trouble allocating memory, it returns 0.  Otherwise it returns 1.

       1 for success, 0 on memory allocation failure.
