the initial buffer wasn't empty.
* Enlarged the minimum header size a bit (one more data_node).

so that the buffer could be smaller than the one requested.
* Rewrote data_node management in the header; now, every data_node knows where it's
placed, and can be actually discarded as needed.
* Rewrote free space management in the header: there is now a free chunk list, so
that all memory can be reused (it's currently only used for data_nodes anyway).

if it won't be added anymore.
* Small fix for set_timer(): now set the timer->due field back to 0 when a
timer is removed - this prevented a timer from being correctly readded later
(possible crash)!
* net_buffer's append_cloned_data() now does some more checks to prevent unnecessary
work and detect wrong arguments.

by the TCP implementation for its reorder and retransmit queues.
* The ipv4_fragment is no longer needed, as we can use the above field there
as well - this saves one extra allocation per received fragment.

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().

slab allocator we'll have one day), I don't feel like digging in an fixing its
bugs.
IOW local pings won't crash the kernel anymore, are no longer detected as
duplicates, and loopback does work now as well.

This also fixes the issue of exporting a C++ API from the kernel.
