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.
Javadocs and cleanups.

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.

- 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

Check bounds at initialization
Remove unused setIPRestriction()

Removed in May 2011 when we added fast tier slices
Also add support in exploratory tunnels
Create MaskedIPSet in peer selectors, pass to ProfileOrganizer.selectXXX() for each call.
Not required for one-hop tunnels.
Disable for test networks (i2np.allowLocal)

disable any chance of JNDI lookups in log4j.properties file by setting %m{nolookups}. I don't think we're actually vulnerable to CVE-2021-44228 if I'm understanding correctly, by default it doesn't seem like we actually use log4j for much of anything and we don't do much logging of arbitrarily crafted remote inputs, but also it seems like this JNDI lookups thing is way more trouble than it could possibly be worth to us. Maybe it's a good idea to make sure it's turned off by default.

- Add fromPort and toPort to Sink interface (breaking API change)
- Change cache maps from Destination to I2PSocketAddress to include port
- Accept host:port for destination in Streamr Client, use port
  as toPort in pinger
- Change to muxed listener in I2PSource, only listen for
  specified protocols
- Eliminate thread and queue in I2PSource, process messages inline
  in the listener
- Add support for handling both repliable and raw datagrams in
  a single I2PSource instance
- Remove verify option from I2PSource and I2PTunnelUDPServerBase,
  always verify repliable datagrams
- Add getPort() method to UDPSource
- Add a constructor to UDPSink to pass in an existing DatagramSocket
- Change I2PTunnelUDPClientBase to receive both repliable and raw
- Change SOCKSUDPTunnel reply handling strategy to key on I2CP toPort;
  remove ReplyTracker; the tunnel would not have worked before, because
  it expected raw replies only but MultiSink required a destination
  to look up where to forward the reply.
- Mark SOCKSUDPTunnel as preliminary; note lack of support
  for raw replies; untested
- Change Streamr Client Pinger to support fromPort
- Change Streamr Server to remember fromPort in subscriptions
  and use it as toPort in data stream
- Move fields to top of classes for sanity
- Cleanups and log tweaks
