Add initial python 3 compatibility to native scripts now that
pyuno supports python3.

This is the result of running the python 2to3 script with
conservative settings.

Still more porting work may be required and any regression
with the default Python 2.7.3 should be considered a bug.

Add support to pyuno so that it will build with and support modern versions
of the system Python.

This is a huge step forward for developers and users of operating systems
that are in the process of migrating to Python 3.x.

Partially inspired by hanya's work.

Restore previous comment now that long_path.patch is back.

IndexWriter.MaxFieldLength.LIMITED caused terms to be silently dropped 
after the 10,000th term in a field. Switch to UNLIMITED which doesnt casue 
this to happen.

This patch was left out from the lucene update in r1337602
and apparently has an origin in BZ #i109096#.
No one so far seems to have noticed negative effects but
after consulting in ApacheConEU it seems a good idea to
keep it.

Special thanks to Steve Rowe.
