int buffer_getline_sa(buffer* b,stralloc* sa);

buffer_getline_sa appends data from the b to sa until a '\n' is found, NOT overwriting the previous content of sa.  The new-line is also appended to sa.

If reading from the buffer or allocating memory fails, buffer_getline_sa returns -1 and sets errno appropriately.  At that point sa may be empty or it may already contain a partial token.

-1 on error (setting errno), 0 on EOF, 1 when successful.

buffer_getline_sa appends instead of overwriting so it can be used on non-blocking sockets (these signal error and set errno to EAGAIN; in this case you can simply call buffer_getline_sa again when select or poll indicate more data is available).
