* First part of ICMP support: this is based on the work by Ivo Vachkov (GSoC

2007), and Yin Qiu (GSoC 2008). And even though I needed to rewrite pretty
  much all of it because of the countless bugs and problems it had, it still
  shares the same architectural problems of introducing a domain dependent
  error mechanism to the upper layers, and needing the
  net_buffer::network_header hack. This I will rework later.
* net_buffer's append_size(), and prepend_size() will now gracefully handle
  buffers without a data node.
