fix margin on bandwidth configuration page, fix alignment on bandwidth configuration page, align informational text to language start

one chance in 64K, broken since 2005
don't revert previous attempted fix using synching,
that's still a good idea

Overhaul CSS n New Install Wizard in order to make it less dependent on absolute positioning. Remove confusing M-Lab measurement table since the meaningful results are already populated in the configuration table. Adjust postioning of some elements on the bandwidth config pages. remove the old images from both themes.

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

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.

Check cert sigs when loading, and log warning on failure

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

SSU: Reduce ack delay to minimize addition to measured RTT

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.
