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

generate msgs 1,5-7
handle msgs 5-7
log tweaks

which bypassed all the checks in HandleFloodfillDatabaseStoreMessageJob
Don't store an entry which is older

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
Enforce signatures in netdb store when key is available
Show family verification status on /netdb
Export our cert to disk if missing
Add stormycloud family cert
Bypass /24 Sybil penalty

msgs 5-7 still TODO
WIP, untested

to store Bob's PeerState directly in PeerTestState
prep for SSU2

Packet building, fix peer test block
Not hooked in

Add min packet size constants and notes
Don't attempt to decrypt a packet as a new inbound session if too small
Remove unused payload[] in IES2, now decrypted in-place
Log level tweaks in Establisher

Rotate the log before we hit the limit, not after

Limit max MTU for HE addresses

even if they would fit in the MTU uncompressed,
to save bandwidth and room for other blocks

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

Fix length calculation to see if new token block will fit in session confirmed
Extend timeout after sending retry
Fix retx timer for sess req after sending token req
Remove dup call to confirmedPacketsSent()
Cancel ack timer when sending acks
Include intro key in firewalled addresses too
Use SSU2 version of ping packet for SSU2 peers
Reduce max padding
Log tweaks

Fix packet length for retransmitted handshake messages
Expire pending acks

round timestamp in Session Created

Clean up and optimize ack handling
Log tweaks and javadocs

MTU and related fixes:
Fix max fragment size
Fix max space for acks
Fix max packet size
Pull MTU from best address in Session Confirmed
Pass MTU from establish state to peer state
Use SSU2 min/default/max MTU in PeerState
Stop looping when out of space in OMF (SSU 1 too)

Correctly calculate skew after retry in establish state
Pass calculated skew from establish state to peer state
Round time in DateTime block
Periodically send DateTime block
Handle DateTime block in peer state

that does not require router.jar
and rework other classes as necessary

Log tweaks
