buffer_putalign - write binary data to buffer

       buffer_putalign is similar to buffer_put.

       The  difference  to  buffer_put  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.
