Expire relay token quickly
Log tweaks

Fix setting local IPv6 MTU when firewalled
Fix publishing MTU when firewalled or hidden
Save local MTU when changing addresses, not when publishing
Add SSU2 MTU methods (no mod 16 required)
Allow MTU up to 1500 for SSU2 transport style
Disable SSU2 at startup if local MTU too low

see gitlab MR !59

Add code for bob rejecting alice peer test address
Don't allow MTU to exceed his MTU
Don't use a token about to expire
Send token with termination message
Add internal type to termination message
log tweaks

to make it more responsive to conditions and a more effective PMTU algorithm.
Move MTU up and down in increments rather than simply shift between min and max
Increase or decrease based on success or failure of each message
Only increase if the successful message was almost as large as current MTU
Clear increase/decrease counters when changing MTU the other way
Don't wait for 10 packets to increase MTU
Reduce max retransmissions from 30% to 10%

see earlier checkin for public keys

so as not to exceed MTU

Prefer SSU2 introducers for slots 1 and 2
log tweaks

Needed for SSU2 handshakes

use in OrderedProperties

Caused SusiDNS and addressbook to be in a different context
addressbook config would be stored in base dir
and subscriptions would not load because it couldn't find i2ptunnel

in SigUtil.fromJavaKey()
as the class does not define equals().
Affects Android family key loading where the class does not match our class.
Tested via unit test to compare provider class sun.security.util.NamedCurve
to our class java.security.spec.ECParameterSpec, untested on Android.
Add conversion test to CertUtil loadcert CLI.

Log tweaks

Reject SSU1/SSU2 relay request mismatch as Bob

Don't send SSU1 relay request to SSU2-connected introducers
and vice versa
Log tweaks

as it is received in-session only
Log tweaks all over

to make it easier to debug SSU2 relay

Automatically configure clients and client tunnels to listen on the container network address instead of the localhost. Closes #358

prevent dup SSU2 introducers take 2

so rest of payload can be processed
Improve debug output on errors
