stralloc_copys - copy data into a stralloc

       stralloc_copys  copies  a  \0-terminated  string  from  buf  into  sa,  without the \0. It is the same as
       stralloc_copyb(&sa, buf, str_len(buf)).

       The data that sa previously contained is overwritten and truncated.

       If stralloc_copys runs out of memory, stralloc_copys leaves sa alone and return 0, otherwise  it  returns
       1.
