- Cleanups
    - Remove some locking
    - Change some longs to ints to save space
    - Remove static logs

    - Auto-hidden mode for bad countries
    - Don't put addresses in our RouterInfo when hidden

When I2P terminates with an OOM error, users are advised to update
$I2P/wrapper.config. That path isn't accurate for the Debian packages.

- merge mbuild_jbigi.sh into build_jbigi.sh and drop mbuild_jbigi.sh
- make build.sh's tests optional
- try to determine the locations of JAVA_HOME and I2P

            to branch 'i2p.i2p' (head a06bf8c92a0e1195b6f98dbad3e8898339bc6053)

    - Fix failsafe shutdown hook broken in 0.8.8;
      HUP, INT, and TERM signals should now shut down cleanly.
    - Shutdown hook no longer prevents other hooks from running
    - Trap HUP, if router.gracefulHUP=true, and do graceful shutdown.
      Only under wrapper, non-Windows.
    - i2prouter stop now uses SIGTERM
    - Implement i2prouter graceful using SIGHUP (ticket #580)
    - Configure wrapper to ignore SIGUSR1 and SIGUSR2 as they will shut down
      or crash the JVM

On systems without an i2psvc group, the postinstall would fail. This change
will add the group if it doesn't exist. Also adding "||true" to the usermod
command in case the command returns a non-zero status.

Before there was a patch to add the -deb1 to the RouterVersion.java file, but
it needed me to update the deb#. With my newly budding regex skills, I'm now manipulating
it using sed and determining the number according to the debian version number.

PN,Pitcairn Islands added; we already had the flag.

With this check-in I'm adding the EXTRAVERSION to our javadocs and the custom
installer targets (if EXTRAVERSION is set in RouterVersion.java). Also,
i2pinstall*jar and i2pinstall.bz2 will be removed when ant clean is run.
