buffer_put - write binary data to buffer

       buffer_put writes len bytes from x to b.

       The  difference  to buffer_putalign is that, when there isn't enough space for new data, buffer_put calls
       buffer_flush before copying any data, while buffer_putalign fills all available space  with  data  before
       calling buffer_flush.

       buffer_put returns 0 if everything was fine, -1 on error (setting errno).
