Fixup test as required

Add long methods, deprecate Date methods

one more TunnelId fixup

and reduce object churn and duplication
Fixup tests, javadocs, logging as required

to prevent failures on connections esp. for hidden mode

Set accurate lengths for zero-copy

WIP, to be hooked in

Store back ref to controller in tunnel
Stop server controller on I2PException
Support generation of keys with fractional days expiration for testing

Remove ratchet tag from RSKM on timeout

Additional checks on ECIES BRR to catch old/buggy routers
Detailed logging of ECIES BRR decrypt fails

to save space; not stored for participating tunnels.

modelled on TCP Reno (RFCs 5681 and 6298)
- Use a single timer per connection
- Resend up to half the un-acked messages per timer event instead of a single message
- Only send either old or new messages, do not mix
- Cache/avoid several timer calls
- Instead of 3 return values, allocating bandwidth is now a boolean function
- Avoid one of the iterations over all un-acked messages every packet pusher loop
- Remove 100 ms failsafe
- Fix OMF debug log NPE
With the same cpu usage the bandwidth is much higher
Significant speed improvement for lossy connections (e.g. wifi)
