WIP - not hooked in, untested - target 1.8.0 / 0.9.54
Requires significant changes to TrackerClient
Adapted from mtn branch i2p.i2p.zzz.udpsnark (2014)
Ref: Proposal 160

Turn jump button-links back into regular-looking hyperlinks when resolution indicates we are not on a mobile device

otherwise relative to plugin name, as before

Linkify start/stop webapp on password page

Required for irc.ilita.i2p

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.

as requested by R4SAS

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
