* Reduced contention for local client delivery
* Drop the new code that munges the wrapper.config. Instead, updates that
need to change it will include their own wrapper.config in the
i2pupdate.zip, overwriting the existing file. If the file
"wrapper.config.updated" is included, it is deleted at first opportunity
and the router shut down, displaying a notice that the router must be
started again cleanly to allow the changes to the wrapper.config to take
effect.
* Properly stop accept()ing I2PSocket connections if we close down the
session (duh).
* Make sure we cancel any outstanding Packets in flight when a connection
is terminated (thanks susi!)
* Split up the I2PTunnel closing a little further.
