Added bsd.java.mk. This adds Java-specific support to ports by

means of a USE_JAVA definition. If a port does not define
USE_JAVA, then this change should not affect that port.

The purpose of this bsd.java.mk file has been extensively
discussed on the freebsd-java mailing list. The current
bsd.java.mk is based on the following specification documents:

http://www.metaverse.nl/~ernst/installing.html
http://www.metaverse.nl/~ernst/writing.html

A proposal that lead to the development of these documents and
finally the current bsd.java.mk file is:

http://www.metaverse.nl/~ernst/freebsd-java-proposal-20011116.html

The bsd.java.mk has been sent to portmgr for review. They had
no objections.
