This has been committed.
People with unusual netgraph usage should contact me
for assistance if things fail.

In particular I would like to get some more pppoe users to try
it as I haven't convinced myself it's tested enough.

For the Netgraph-aware, the following changes have been made.
1/ data and contol-messages are now delivered as part of a larger
entity called an 'item'. Thus the prototypes for these methods has 
changed and the code must be changed to free this (or not) as required.

2/ piggyback responses have been removed, The new response method 
is almost as quick and much cleaner.

3/ All nodes have queues into which items are place IFF 
there is lock contention and teh data cannot be processed immediatly.

I expect the code to be a LITLE shaky for a few days around the time
when nodes are deleted. but operation seems solid.
