Enable tunnel testing when without addresses (ticket #1835)
Use fast peers for inbound tunnels when without addresses (ticket #1835)

Change from 60s DHS to 60m DBF
Use reply key as filter key, not first part of
encrypted data, to match the specs and hopefully reduce dups
BuildMessageProcessor cleanups
log and stat tweaks
remove deprecated methods
remove some timing measurements
javadocs

eliminate caching previously enabled for routers with high memory limits
Log tweak on sig verify fail
DataHelper.writeLong() to write(byte) conversion
DatabaseEntry: Remove deprecated, unused setRoutingKey()

(which is useless) on signature verification fail,
in an attempt to find the culprit

  - Change addCapabilities() to getCapabilities()
  - Add netdb family sign/verify utility (ticket #1510)
    (verify not yet used)
RouterInfo:
  - Remove addCapability() and delCapability()
StatPublisher:
  - Remove Service interface, not required
  - Consolidate getCapabilities() and network ID here
  - Add family signatures
  - Remove unused coreVersion and stat_uptime (as of 0.9.24)

omits SAM, BOB, reflection, commented-out code, and a few other places

NetDb: Drop all-zero lookups and stores, add stats
SSU:
 - Fix debug logging of dumped packets
 - Drop sessions with bad clock skew, banlist peer, add stats
 - Drop sessions with corrupt DSM, banlist peer, add stats
Log tweaks

- FloodfillMonitorJob:
  - Use avg of router.tunnelBacklog instead of current backlog
- Some language/spelling fixes

to reduce object churn, we only need one
Add DeliveryInstructions.create() to return immmutable
local instructions, to reduce object churn
Minor cleanups

Remove meeh.i2p as update host (ticket #1515)
Re-add 193.xxx https reseed
Fix SocketManagerFactory property handling
Restore UPnP locale fix lost in the merge
i2ptunnel finals
I2NP unique id fixes
duplicate done() in ReseedChecker
bigger langbox in CSS
reformatting
Javadocs

- RI javadoc clarifications WRT caps

in case we ever want to use them for options

Move some data structures away from ByteArray; offsets were always zero
  - New BuildRequestRecord constructors
  - BuildRequestRecord field becomes final byte[222]
  - IV becomes byte[16]
  - Build record becomes EncryptedBuildRecord
Remove extra copy in BuildRequestRecord.encryptRecord()
Remove unused BuildRequestRecord.readOurIdentityMatches()

- Set lookup type flags even if no reply tunnel specified
- Reduce object churn when writing some messages

whether specified in the caps or the cert

to replace all-zeros hash, and ease implementation for
separate LS and RI databases, as documented in i2np spec.

  - Move from core to RouterKeyGenerator in router.jar
  - Leave RoutingKeyGenerator as a simple abstract class
  - DatabaseEntry now uses timestamp instead of mod data
    to determine if mod data has changed. Don't expose
    mod data to DatabaseEntry any more.
  - I2PAppContext.routingKeyGenerator() now returns null;
    you must be in RouterContext to get a generator.

BuildRequestor: Randomize timestamp to prevent hop ID at top of hour
