but it also didn't create valid buffers in a number of cases:
* remove_header() did not work correctly if more than one node had to be
removed or came after the first node to be kept.
* prepend_size() did not update the offset of the following nodes.
* write_data() and read_data() both did not update the data pointer, and thus
always copied the same data to every node.
* merge_buffer() inserted the nodes in the wrong order when prepending a buffer.
* added a dump_buffer() function and lots of additional debug output (currently
commented out)
* simplified split_buffer() a bit more.
* implemented remove_trailer().
