LP 1827051: Remove Java Code, etc.

Java support in OpenSRF does not build and is out of date with current
OpenSRF features.  No one has the intention to fix it, so this commit
removes Java from the code, build files, and documentation.

To test that Java is indeed broken, configure OpenSRF with the
--enable-java option and then watch the make fail as it tries to pull
in missing dependencies.

To test this branch, simply apply it and see that the option to enable
Java is gone along with all of the obsolete code and build instructions.
