* drop the outbound message as soon as it expires rather than transferring an expired message
* drop hard any outbound message that takes us over 5 seconds to process (if we have a 5s message processing time, we do no one any good)
* don't try to resend (only useful when dealing with multiple transports - aka insufficiently tested code)
* don't republish netDb messages as often
* reduced the number of tags passed when garlic routing a tunnelCreate
* catch timeout on a tunnel message quicker
* give a tunnel message a new messageId per hop
* added some more infrastructure for per-hop tunnelId
* removed SourceRouteBlock & SourceRouteReplyMessage, as they're a redundant concept
that 1) takes up bandwidth 2) takes up CPU 3) smell funny.
now the TunnelCreateMessage includes a replyTag, replyKey, replyTunnel, and
replyGateway that they garlic encrypt their ACK/NACK through and with.
* tunnelCreateMessage doesn't need a seperate ACK - either we get a
TunnelCreateStatusMessage back or we don't.
* message structure mods for unique tunnel ID per hop (though currently all hops have
the same tunnel ID)
(making a searchReply message ~100 bytes, down from ~30KB, and the lookup message ~64 bytes, down from ~10KB)
* when we get the netDb searchReply or lookup message referencing someone we don't know,
we fire off a lookup for them
* reduced some excessive padding
* dropped the DbSearchReplyMessageHandler, since it shouldn't be used (all search replies
should be handled by a MessageSelector built by the original search message)
* removed some oddball constructors from the SendMessageDirectJob and SendTunnelMessageJob (always must specify a timeout)
* refactored SendTunnelMessageJob main handler method into smaller logical methods
cleaned up rebuild / verification process so that the select*TunnelIds will always return what is necessary
for the moment, don't automatically kill all tunnels of a peer who fails just once (they can recover)
logging
new piece of data exposed and maintained is a list of router contexts - shown as a singleton off RouterContext - allowing an app in the same JVM to find the routers (and chose between which one they want)
one for peer selection and organization. reliability is kept around
for the moment and shown on the router console, but only to provide a
comparison (it is not used in any way)
* new stat in the TunnelHistory: failRate
* coallesce TunnelHistory stats (duh!)
* new ProfileOrganizer CLI ("ProfileOrganizer[ filename]*"
* implement reasonable 'failure' logic - if they are actively rejecting
tunnels or tunnels they've agreed to are failing, mark them as failing
* when choosing peers to test, exclude all fast ones
