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.
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
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.

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
Return a result code from verify()
Load all known certs at startup rather than continually reloading them
Only give full verified status to known keys

Remove unused payload[] in IES2, now decrypted in-place
Log level tweaks in Establisher
Save data messages received before or immediately after session confirmed
by queueing them for processing after the PeerState2 is created.
The fragments for the first I2NP message from Alice to Bob are frequently lost,
this will hopefully fix it.
Not fully tested, needs wider network testing.
Avoid relaying until it's implemented:
Don't use SSU2 for an SSU address with introducers (fixes NPE)
Don't connect to SSU2 address without host/port
Don't ask for relay tag
Log tweaks
