Indexing and Searching works!

Garrett Rooney
This is all hardly tested at all, but as of my last few commits to
Subversion the GCJ backed code now has basic indexing and searching
working.  Check out test/main.c [1] for an example of how to use the new
API.

For the curious, it turns out that a lot of my problems were being
caused by compiling Java code with a 1.5.0 JDK, which GCJ appears to nto
like.  I ran into a few other problems with GCJ itself, both of which I
was able to solve by writing small amounts of Java code to make the
calls I was unable to convince GCC to let me do from C++.

Next on the todo list is trying to get the CLI and unit tests running
again, and making the build system a bit more sane.

Where do I get this Field.h... I didn't see any rules for it in the
Makefile... I assume its generated from the .jar file?

Thanks,

Run 'make headers' to generate the CNI headers for the Lucene java
libraries.  You'll see two errors, because there are two classes that
gcjh can't correctly parse, and it'll leave a bunch of crap sitting in a
temp directory that you'll probably want to delete, but it'll also dump
all the required headers in include/org/apache/lucene.

Another of the "things I need to clean up" ;-)
