Don't set our RI loaded from disk if too old
Rekeying was prevented by previous checkin,
but this fixes root cause

Reset uptime on soft restart
Don't rekey after failure to store our RI due to clock skew
Change comm system state during soft restart
Restarter log tweaks

send timeout code in termination
remove unused intro key block handling
log tweaks

even if we don't have enough peers

for efficient lookup and to prevent display of dup prefixes

Arrays.hashCode() interacted badly with it,
causing numerous false positives

Revert related parts of "Prep for fragmented RI",
we are now fragmenting Session Confirmed instead.
Fragment and send multiple Session Confirmed packets if required
Reassemble Session Confirmed packets

Don't process ack block identical to previous received

bump -12

WIP, not hooked in

Fix IES2 not being removed from pending after complete
Don't send DSM after handshake
Validate conn ID before pkt type for data pkts
More log tweaks

SSU: Increase min pending establish states limit (unless slow)
Reduce IB establish timeout to 15s
Log pending inbound establish states when limit exceeded
Log tweaks to add establish state lifetime
Bump -11

when loaded from router.info, and discard if invalid or when family changed.
This fixes some routers out there with bad sigs.
Don't loop forever through LoadRouterInfoJob.

Call messagePartiallyReceived() even for dups or expired messages
so an ack is generated.

See previous checkin for SSU 1.
This change dramatically reduces the measured RTT to get it much closer to the real RTT by reducing the ack delay.
With the ack delay dependent on the measured RTT, the measured RTT will increase.

Simulation results: For a denominator D in the ack delay calculation (currently 2) and a true RTT = TRTT:
For D <= about 2, measured RTT -> TRTT + 2 * TRTT/D For D >= about 4, measured RTT -> TRTT + TRTT/D

In other words, for D == 2, measured RTT -> 2 * TRTT. For a TRTT of 50, the measured RTT is 100.
D == 2 is too small. It's been like that since 2005.
Testnet results: measured RTT 80-90

This changes D to 6. measured RTT -> 6/5 * TRTT.
Simulation results: For a TRTT of 50, the measured RTT is 58.
Testnet results: measured RTT 60

Remove padding and unknown block callbacks
Remove handshake state logging in IES2 now that i2pd works

from ihost0 to itag0, because SSU2 probably won't use ihost

both inbound and outbound

Synch fields in the data messages both directions,
after one report of zero session ID in MessagePayloadMessage
to an external client on fast hardware with Java 18.
Add new constructors for efficiency.
Deprecated setters, unit tests not changed, TODO.
Should fix all the other messages also, TODO.

Store OB tokens by IP/port
Centralize token generation and expiration in Establishment Manager
Add methods to flush OB tokens on IP/port change
Log tweaks
Javadoc fix

Don't overwrite an existing family keystore file
Don't allow starting a new family with an existing family keystore file
Don't add family to RI until we have restarted and have a keystore file
Don't fail a netdb store for no family sig
Don't ever fail our own netdb store for family errors, to avoid rekey/restart
