Building Jython3

Starting a new thread, and including Isaiah Peng in case he has some
insights. Hi Isaiah! We are starting to discuss how to make the
Jython3 sandbox the main line for development after the Jython 2.7.1
release.

I took a look, and made a couple of changes that get Jython3 building
for me, so the tip of https://github.com/jython/jython3 should now
build (I hope).

For me though, it does not run. I always get:

$ ./dist/bin/jython
Exception in thread "main"
Exception: java.lang.NullPointerException thrown from the
UncaughtExceptionHandler in thread "main"

Investigating further, the issue seems to have been introduced on Sept
19 in this commit, which unfortunately, is a biggish one:

"""
commit 308a17a4e9972aa3814a358917ffbd25fd976864

    rewrite zipimporter, detach from the shared importer abstract
class, since classpathpyimporter is currently not functional
"""

The last commit that works on my machine is the one just before:

"""

    throw OSError for negative seek position
"""

Hope this helps!
