- Always use a lease as the reply tunnel when publishing LS through a client tunnel
  This ensures we're not using about-to-expire tunnels for the reply,
  and ensures the ff is able pick an alternate
- Don't count skipped peers as attempted in FloodfillVerify
- Pass failed and skipped peers to FloodfillVerify job to be skipped there also
- Pass failed and skipped peers from FloodfillVerify job to the next StoreJob on failure
- Consolidate common reply token generation code in StoreJob
- Ensure tunnel diversity in StoreJob retries by only
  using tunnels closest to the target for the first request.
  This increases reliability by not reusing the same tunnels for all retries.
- Refactor StoreState to rework inefficient methods and unused data
- Clean up commented-out code in StoreState
- Log tweaks

Don't requeue on failure if there is a newer LS, KNDF will have already done that.

by only using tunnels closest to the target for the first request.
This increases reliability by not reusing the same tunnels for all retries.

This reduces the max lookup rate

10 minute rate is too short
Change to getAvgOrLifetimeAvg()
Reduce max time

Actually update the stat for stores in dbStoreSent();
we are generally storing to different ffs than lookups, so we need the
stat for stores as well, since we use it as the timeout in StoreJob.

Change from 1-day to 1-hour stat.
Switch to avgOrLifetimeAvg() so the rate is always valid.
Reduce max time used for timeout.
This allows more peers to be tried before total timeout
Previously, the per-peer timeout was almost always the max.
Make sendStore() package private.

so that torrents stop when the router stops and restart when the router restarts.

- Use BWLimits from the DirMonitor as a periodic test that the router is there
- DirMonitor does not attempt to autostart torrents if BWLimits test fails
- DirMonitor does autostart existing torrents when BWLimits test passes again
- Register disconnect listener with socket manger and stop all torrents on disconnect
- Use stopTorrent(true) on router errors to prevent changing the persisted torrent running status
- Change autostart default to true for standalone

Possibly more todo for corner cases or other start/stop/fail scenarios.

in client-side AppContext SimpleSession, to prevent router-side
error message when closing socket, e.g. for BW limits check

it's not a i2pd bug at startup that fixes itself.

as requested by R4SAS

- Write directly from writer threads, except for during establishment and when write doesn't complete; throw those to the pumper as usual
- New NTCPCon writelock, readlock, and statlock (formerly all on NTCPCon.this) to prevent deadlocks
- NTCPCon chan and key now volatile, remove synch to prevent deadlocks
- All interestOps changes now lock on the key via setInterest() and clearInterest() since changes may now happen in multiple threads
- Set _paddingConfig at initialization to avoid NPE

Greatly reduces pumper loops and CPU

and don't IAE on 8 byte negative value

rather than using a fixed value of 6
so IPv6 default is now 4
