- Don't require AES keys for short records
- Derive keys from noise ck
- Use derived keys to garlic-encrypt reply at OBEP
- Register reply key with SKM
- Only use short message for client tunnels if client supports EC
- Set nonce for chacha/poly reply record
- Add tagsReceived() for single tag to MuxedSKM
- Add extended TunnelCreatorConfig.toStringFull()
- BRR toString() enhancements
- Test enhancements

- remove ITBM
- remove plaintext slot from OTBRM

- Remove ITBM, change record length from 236 to 218 bytes
- Fix check of blank record in BuildReplyHandler
- Fix offset constants for short record in BuildRequestRecord
- Fix BuildMessageTestStandalone test 6 (short inbound)
- ITBM class removal TODO

- Add new internal-only ShortTunnelBuildReplyMessage,
  for processing of STBM as a reply.
- Add support for inbound tunnel tests to TunnelBuildMessageStandalone.
  The ITBM test is WIP.
- Add checks for unset plaintext record in ITBM and OTBRM

WIP, still disabled, proposal not complete

- Use ChaCha20 to encrypt/decrypt records
- Add OTBRM methods for plaintext record
- Add OTBRM checks for correct plaintext slot number
- Add BRR checks to prevent use of nonexistent AES key/IV
- Set plaintext reply at OBEP in BuildHandler
- Allow OTBRM in InboundMessageDistributor
- Remove timing measurements in BuildMessageProcessor.decrypt()
- Add test to BuildMessageTestStandalone for outbound build
- Add check for all replies to BuildMessageTestStandalone
- Log tweaks

Fixup test as required

and reduce object churn and duplication
Fixup tests, javadocs, logging as required

to save space; not stored for participating tunnels.

Preliminary, proposal not finalized, subject to change
Not yet compatibility tested with other implementations
Add peers to match requested length for explicitPeers
remove commented out code
log tweaks

never worked - didn't check result, processed own config

Fix max ID

Remove cast warnings
Fix RouterAddress.setExpiration() to match javadoc, used only by tests

Return failure codes from LCM to client (ticket #1939)

replaces i2np.udp.allowLocal and i2np.ntcp.allowLocal,
fixes test networks (ticket #1875)
