- Fix about 9 NPEs
- Fix numwant in magnet mode
- Send metadata size in extension handshake
- Open trackers are primary if we don't have primary trackers
- Add missing break in port message handling

      - Move BWLimits and DestLookup message support from
        I2PSimpleSession to I2PSessionImpl
      - Include the Hash in the DestReplyMessage on a failed lookup
        so the client may correlate replies
      - Add support for parallel lookups and BWLimits requests
      - Add support for specifying the timeout for DestLookups
        (can only be smaller than the router timeout for now)
      - Extend dest lookup router timeout from 10s to 15s

                  add i2p.insecureFiles option to disable (default false)

  stopped announces go out and reopen it
- Logging tweaks

      Use context random for shuffle; other cleanups

  - Rework PeerID class so it depends only on peer desthash, since
    peer ID is not available with compact format. Implement deferred
    lookup of destination.
  - Implement compact tracker requests and response handling
    (may not be the final format)
  - Fix Peer hashCode()
  - Java 5

      - Comment out old proxy stuff

      - New I2PSocketEepGet fetches through existing tunnels
        rather than through the proxy
      - Use new eepget for i2psnark
      - Add a fake user agent for non-proxied fetches
      - Cleanups

    * Code Janitor time! Many fixes and documenting fixes that should be
      done in the future. for the most part, this is a general code cleanup.
    * On smaller/embedded systems, the "final" keyword cleanups will have
      more of an impact than on larger systems.
    * Document missing hashCode() methods.
    * Unhide more variables to make code easier to read.

Eliminate all uses of the current working directory, and
set up multiple directories specified by absolute paths for various uses.

Add a WorkingDir class to create a user config directory and
migrate files to it for new installs.
The directory will be $HOME/.i2p on linux and %APPDIR%\I2P on Windows,
or as specified in the system property -Di2p.dir.config=/path/to/i2pdir
All files except for the base install and temp files will be
in the config directory by default.
Temp files will be in a i2p-xxxxx subdirectory of the system temp directory
specified by the system property java.io.tmpdir.

Convert all file opens in the code to be relative to a specific directory,
as specified in the context. Code and applications should never open
files relative to the current working directory (e.g. new File("foo")).
All files should be accessed in the appropriate context directory,
e.g. new File(_context.getAppDir(), "foo").

The router.config file location may be specified as a system property on the
java command line with -Drouter.configLocation=/path/to/router.config
All directories may be specified as properties in the router.config file.

The migration will copy all files from an existing installation,
except i2psnark/, with the system property -Di2p.dir.migrate=true.
Otherwise it will just set up a new directory with a minimal configuration.

The migration will also create a modified wrapper.config and (on linux only)
a modified i2prouter script, and place them in the config directory.

There are no changes to the installer or the default i2prouter, i2prouter.bat,
i2prouter, wrapper.config, runplain.sh, windows service installer/uninstaller,
etc. in this checkin.


    *  Directories. These are all set at instantiation and will not be changed by
    *  subsequent property changes.
    *  All properties, if set, should be absolute paths.
    *
    *  Name	Property 	Method		Files
    *  -----	-------- 	-----		-----
    *  Base	i2p.dir.base	getBaseDir()	lib/, webapps/, docs/, geoip/, licenses/, ...
    *  Temp	i2p.dir.temp	getTempDir()	Temporary files
    *  Config	i2p.dir.config	getConfigDir()	*.config, hosts.txt, addressbook/, ...
    *
    *  (the following all default to the same as Config)
    *
    *  Router	i2p.dir.router	getRouterDir()	netDb/, peerProfiles/, router.*, keyBackup/, ...
    *  Log	i2p.dir.log	getLogDir()	wrapper.log*, logs/
    *  PID	i2p.dir.pid	getPIDDir()	wrapper *.pid files, router.ping
    *  App	i2p.dir.app	getAppDir()	eepsite/, ...
    *
    *  Note that we can't control where the wrapper actually puts its files.

All these will be set appropriately in a Router Context.
In an I2P App Context, all except Temp will be the current working directory.

Lightly tested so far, needs much more testing.

      will not be rescheduled or cancelled, to reduce SimpleTimer
      lock contention

    - Don't create SnarkManager instance until first call,
      so it doesn't create the i2psnark dir, read the config,
      etc., for single Snark instances.
    - Don't read i2psnark.config twice; fix setting
      i2psnark.dir
    - More Snark constructor changes for calling from router
    - Make max connections per torrent configurable

    - Remove static instances of I2PSnarkUtil, ConnectionAcceptor,
      and PeerCoordinatorSet
    - Convert static classes in Snark to listeners
    - Fix Snark to work in single torrent mode again
    - Should now work with multiple single Snarks

  - Refactor to allow running a single Snark without a SnarkManager again,
    by moving some things from SnarkManager to I2PSnarkUtil,
    having Snark call completeListener callbacks,
    and having Storage call storageListener callbacks.
    This is in preparation for using Snark for router updates.
    Step 2 is to allow multiple I2PSnarkUtil instances.
  - Big rewrite of Storage to open file descriptors on demand, and
    close them when unused, so we can support large numbers of torrents.

    * NTCP: Don't drop a connection unless both directions are idle;
            Fix idle time for outbound connections
    * Outbound message: Make sure cached lease is in current leaseSet
    * Stats: Put all NetworkDatabase stats in same group
    * TunnelPool: Stop building tunnels and leaseSets after client shutdown
    * i2psnark: Add locking to prevent two I2CP connections
