Request handling:
- sendAsync() the Accepted in RequestHandler. Should *significantly* reduce request latency (maybe 50%) while making no difference to bandwidth usage. We don't need to wait for the round trip, it gives very little protection against DoS to do so, and not doing so helps with load.
- Locking fix (using wrong lock accessing byte totals on RequestHandler) - hopefully more accurate byte totals => better load management.
Memory usage / memory DoS'es:
- Clear the message send queue when a node reconnects with a different bootID.
- Dump the message queue in various cases and the tracker in various cases of disconnect()/forceDisconnect(). Generally if we expect to be down for a long time, dump it.
- Dump the message queue 1 hour after disconnection if not reconnected at least once in that time.
Send-queue DoS: A node could connect and send requests and never ack any packets. No packets would be sent to it, but it could keep on sending requests, and the output would accumulate in RAM until the node OOMed.
- Reject requests from a node if its send queue is over 4MB or over 10 minutes at the current throttle rate.
First time wizard:
- Link to the node at the end of the wizard.
- Make the link to continue with the wizard at the beginning more obvious.
Dev stuff:
- Move timeLastDisconnect/timePrevDisconnect into PeerNode.
- Imports.
- Indenting.
- Comments.
- Code clarifications.
L10n
- Some cosmetic changes to the english strings
